Due to some bad practices from one of our internal users. We need to transfer all activities (mails, notes, etc) from one contact to another contact. I was trying to achieve this via UI and I could not find a way to do this.
Is this possible? I'm looking for any way to achieve this, wether is CRMTool, SSIS, UI or any other way. Only admins will do this so we do not need anything fancy as it will be done maybe 4 times a year to clean up some data.
Thanks a lot :)
Tried using UI but no success.
I can think of two ways to do these updates.
The first method is selecting a view on an activity where the owner is listed (i.e. All Phone Calls) and exporting to Excel. This downloads a XLSX with some hidden columns at the start where IDs for the records are kept. You then update the owner column with the new owner (take care of copying the exact fullname), and then importing the Excel spreadsheet again. You would need to repeat this export/import steps for each activity type (phone calls, email, etc.). So this might be impractical if you have a large volume of date, because of the need to repeat and because there are max numbers of records that you can export.
The other way to do this is using some .NET code. Of course, to do this you will need to use Visual Studio 2019.
If that's the case, this will do the trick:
using System;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Query;
using Microsoft.Xrm.Tooling.Connector;
namespace ChangeActivitiesOwner
{
class Program
{
static void Main(string[] args)
{
string connectionString = "AuthType=Office365;Url=<TODO:URL>;Username=<TODO:User>;Password=<TODO:Pass>;";
string oldUserFullname = ""; // TODO: place here fullname for the user you want to overwrite
string newUserFullname = ""; // TODO: place here fullname for the user you want to overwrite with
CrmServiceClient client = new CrmServiceClient(connectionString);
IOrganizationService service = client.OrganizationWebProxyClient != null ? client.OrganizationWebProxyClient : (IOrganizationService)client.OrganizationServiceProxy;
QueryByAttribute qbyaOldUser = new QueryByAttribute("systemuser");
qbyaOldUser.AddAttributeValue("fullname", oldUserFullname);
Guid olduserid = (Guid)service.RetrieveMultiple(qbyaOldUser)[0].Attributes["systemuserid"];
QueryByAttribute qbyaNewUser = new QueryByAttribute("systemuser");
qbyaNewUser.AddAttributeValue("fullname", newUserFullname);
Guid newuserid = (Guid)service.RetrieveMultiple(qbyaNewUser)[0].Attributes["systemuserid"];
foreach (string activity in new string[]{ "task", "phonecall", "email", "fax", "appointment", "letter", "campaignresponse", "campaignactivity" }) // TODO: Add other activities as needed!!!
{
QueryExpression query = new QueryExpression(activity)
{
ColumnSet = new ColumnSet("activityid", "ownerid")
};
query.Criteria.AddCondition(new ConditionExpression("ownerid", ConditionOperator.Equal, olduserid));
foreach (Entity e in service.RetrieveMultiple(query).Entities)
{
e.Attributes["ownerid"] = new EntityReference("systemuser", newuserid);
service.Update(e);
}
}
}
}
}
Please complete the lines marked with "TODO" with your info.
You will need to add the packages Microsoft.CrmSdk.CoreAssemblies, Microsoft.CrmSdk.Deployment, Microsoft.CrmSdk.Workflow, Microsoft.CrmSdk.XrmTooling.CoreAssembly, Microsoft.IdentityModel.Clients.ActiveDIrectory and Newtonsoft.Json to your solution, and use .NET Framework 4.6.2.
Hope this helps.
Running Dynamics CRM 2011 rollout 3. Need to update millions of customer records periodically (delta updates). Using standard update (one by one) takes a few weeks. Also we don't want to touch the DB directly as it may break stuff in the future.
Is there a bulk update method in the Dynamics CRM 2011 webservice/REST API we can use? (WhatWhereHow)
I realize this is post is over 2 years old, but I can add to it in case someone else reads it and has a similar need.
Peter Majeed's answer is on target in that CRM processes requests one record at a time. There is no bulk edit that works the way you are looking for. I encourage you not to touch the DB directly if you need/want Microsoft support.
If you are looking at periodic updates of millions of records, you have a few options. Consider using Scribe or develop your own custom import utility or script using the CRM SDK.
Scribe is probably going to be your best option since it is cost effective for data imports and will allow you to easily update and insert from the same file.
If you write your own .Net/SDK based utility, I'd suggest making it multithreaded and either programmatically break up your input file in memory or on disk and have each thread work with its own subset of the data - that is, of course, if the order of execution does not have to be chronological according to the contents of the input file. If you can divide and conquer the input file over multiple threads, you can reduce the overall execution time considerably.
Also, if your corporate policy allows you to have access to one of the CRM Servers and you can place your code directly on the server and execute it from there - you can eliminate the network latency between a workstation running the code and the CRM web services.
Last but not least, if this large volume of import data is coming from another system, you can write a CRM plug-in to run on the Retrieve and RetrieveMultiple messages (events) in CRM for your specific entity, programmatically retrieve the desired data from the other system (and if the other system is unavailable - just use the cached copy in CRM), and keep CRM up to date in real-time or on a 'last-cached-on' basis. This is certainly more coding effort, but it potentially eliminates the need for a large synchronization job to be run every few weeks.
Yes and no, mostly no. Someone can correct me if I'm mistaken, in which case I'll gladly edit/delete my answer, but everything that's done in Dynamics CRM is done one at a time. It doesn't even try to handle set-based inserts/updates/deletes. So unless you go straight to direct DB operations, it will take you weeks.
The webservice does allow for "bulk" inserts/deletes/updates, but I put "bulk" in quotes because all it does is set up an asynchronous process where it does all the relevant data operations - yep - one at a time. There's a section of the SDK that addresses this sort of data management (linked). And to update the records this way, you'd have to first suffer the overhead of selecting all the data you want to update, then creating an xml file that contains the data, and finally updating the data (remember: one row at a time). So it would actually be more efficient to just loop through your data and issue an Update request for each yourself.
(I will note that our org hasn't experienced any memorable issues regarding direct DB access to handle what the SDK doesn't, nor have I seen anything in my personal internet readings that suggest others have.)
Edit:
See iFirefly's answer below for some other excellent ways to address this issue.
I realize this is an old question but it comes up high on "CRM Bulk Update" so the Update Rollup 12 feature ExecuteMultiple needs to be mentioned here -- its not going to work around your issue (massive volume) because as iFirefly and Peter point out CRM does everything one at a time. What it does do is package all your requests into a single envelope letting CRM handle the execution of each update and reduce the number of round trips between your app and the server if you do end up issuing an Update request for every record.
This is quite an old question, but nobody mentioned the fasted way (but also the most challenging) of updating/creating huge amounts of records in CRM 201X - using built-in import feature, which is totally doable using CRM SDK. There is a perfect MSDN article about that:
https://msdn.microsoft.com/en-us/library/gg328321(v=crm.5).aspx. In short you have to:
1) Build Excel file containing the data you want to import (simply export some data from CRM 201X and check how the structure looks like, remember that the first 3 columns are hidden)
2) create Import Map entity (specify the file you created)
3) Create column mappings if necessary
4) Create Import and ImportFile entity, providing proper mappings
5) Parse data using ParseImportRequest
6) Tranform data using TransformImportRequest
7) Import data using ImportRecordsImportRequest
This were the steps for CRM 2011, now in 2017 we have more versions available and there are slight differences between them. Check the sample that is available on MSDN and in SDK:
https://msdn.microsoft.com/en-us/library/hh547396(v=crm.5).aspx
Of course point 1, will be the most difficult part, because you have to build XML or docx file perfectly corresponding to what CRM expects, but I'm assuming you are doing it from external app, so you can use some great .NET libraries that will make things much simpler.
I never saw anything faster than standard CRM import when it comes to updating/creating records, even if you go for parallelism and Batch Update requests.
If something goes wrong with the MSDN sites, I'm posting here an example from the link above that is showing how to import data to CRM programatically:

Not sure how this would go with millions of records, but you can select your records, then click the Edit button in the ribbon. This will bring up the "Edit Multiple Records" dialog. Any changes you make will be applied to all your records.
The BulkUpdate API works well for me; it is 10 times faster than updating records one at a time. Following is a snippet that performs a bulk update:
public override ExecuteMultipleResponse BulkUpdate(List<Entity> entities)
{
ExecuteMultipleRequest request = new ExecuteMultipleRequest()
{
Settings = new ExecuteMultipleSettings()
{
ContinueOnError = true,
ReturnResponses = true
},
Requests = new OrganizationRequestCollection()
};
for (int i = 0; i < entities.Count; i++)
{
request.Requests.Add(new UpdateRequest() { Target = entities[i] });
}
return (ExecuteMultipleResponse) ServiceContext.Execute(request);
}
I worked on a very large data migration project for Dynamics CRM 2011. We needed to load about 3 million records over a weekend. I ended up building a console application (single thread) and ran multiple instances on multiple machines. Each console application had an id (1, 2, etc.) and was responsible for loading segments of the data based on a unique SQL WHERE clause that matched the application's id.
You could do the same thing with updates. Each instance could query a subset of the records to update and can perform the updates via the SDK. Since we loaded millions of records over a weekend I think you could perform millions of updates (if relatively small) in just a few hours.
Microsoft PFE team for dynamics CRM wrote
new Another CRM SDK library that make use of parallelization
to bulk execute requests ensuring thread safety.
You may try : Parallel Execute Requests
I would be interested to know if it works and scales to millions of records.
CRM doesn't implement a way to update bulk data; there are 3 ways to improve the bulk update operation performance but internally they cannot change the fact that CRM updates record one by one.
Basically the ideas are:
reduce the time wasted on communicating to CRM server
use parallelism to do multiple operations at the same time
make sure the update process does NOT trigger any workflows/plugins. Otherwise you might never see the end of the process...
3 ways to improve bulk operation performance:
After RollUp 12 there is a ExecuteMultipleRequest feature, which allows you to send up to 1000 requests at once. This means you may save some time from sending 1000 requests to CRM web service, however, these requests are processed one after another. So if your CRM server is well configured, most likely this method won't help too much.
You may use OrganizationServiceContext instance to do bulk update. OrganizationServiceContext implements unit of work pattern so you can do multiple updates and transmit these operations to the server in one call. Comparing to ExecuteMultipleRequest, it doesn't have a limit on request amount, but if it encounters a failure during the update, it will rollback all the changes.
Use multithreading or multitask. Either way would improve the speed, but they are likely to generate some connection failures or SQL errors, so you would need to add some retry logic in the code.
One of my client had exactly the same problem. He solved it by creating a custom ETL and doing parallelism attacking two front-end. The whole thing was made in C#. Nowaday, it could be possible with KingswaySoft or Scribe.
When data is entered, it ultimately needs to be saved remotely on a server. I do want the app to work if there is no data connection at the time also, so I need to save everything locally on the phone too. The app can then sync with the server when it gets a connection.
This brings up a little issue. I'm used to saving everything on the server and then getting the records back with id's generated from the server for them. If there is no connection, the app will save locally to the phone but not the server. When syncing with the server, I don't see a way for the phone to know when a record comes back which locally record it's associated with. There isn't enough unique data to figure this out.
What is the best way to handle this?
One way I've been thinking is to change the id of the records to a GUID and let the phone set the id. This way, all records will have an id locally, and when saving to the server, it should still be a unique id.
I'd like to know what other people have been doing, and what works and what doesn't from experience.
This is how we done with a first windows phone 7 app finished few days ago with my friend.
It might not be the best solution but 'till additional refactoring it works just fine.
It's an application for a web app like a mint.com called slamarica.
If we have feature like save transaction, we first check if we have connection to internet.
// Check if application is in online or in offline mode
if (NetworkDetector.IsOnline)
{
// Save through REST API
_transactionBl.AddTransaction(_currentTransaction);
}
else
{
// Save to phone database
SaveTransactionToPhone(_currentTransaction);
}
If transaction is successfully saved via REST, it responses with transaction object and than we save it to local database. If REST save failed we save data to local database.
private void OnTransactionSaveCompleted(bool isSuccessful, string message, Transaction savedTransaction)
{
MessageBox.Show(message);
if(isSuccessful)
{
// save new transaction to local database
DatabaseBl.Save(savedTransaction);
// save to observable collection Transactions in MainViewModel
App.ViewModel.Transactions.Add(App.ViewModel.TransactionToTransactionViewModel(savedTransaction));
App.ViewModel.SortTransactionList();
// Go back to Transaction List
NavigationService.GoBack();
}
else
{
// if REST is failed save unsent transaction to Phone database
SaveTransactionToPhone(_currentTransaction);
// save to observable collection Transactions in MainViewModel
App.ViewModel.Transactions.Add(App.ViewModel.TransactionToTransactionViewModel(_currentTransaction));
App.ViewModel.SortTransactionList();
}
}
Every Transaction object has IsInSync property. It is set to false by default until we got confirmation from REST API that it's saved successful on the server.
User has ability to refresh transactions. User can click on a button Refresh to fetch new data from the server. We do the syncing in the background like this:
private void RefreshTransactions(object sender, RoutedEventArgs e)
{
if (NetworkDetector.IsOnline)
{
var notSyncTransactions = DatabaseBl.GetData<Transaction>().Where(x => x.IsInSync == false).ToList();
if(notSyncTransactions.Count > 0)
{
// we must Sync all transactions
_isAllInSync = true;
_transactionSyncCount = notSyncTransactions.Count;
_transactionBl.AddTransactionCompleted += OnSyncTransactionCompleted;
if (_progress == null)
{
_progress = new ProgressIndicator();
}
foreach (var notSyncTransaction in notSyncTransactions)
{
_transactionBl.AddTransaction(notSyncTransaction);
}
_progress.Show();
}
else
{
// just refresh transactions
DoTransactionRefresh();
}
}
else
{
MessageBox.Show(ApplicationStrings.NETWORK_OFFLINE);
}
}
private void DoTransactionRefresh()
{
if (_progress == null)
{
_progress = new ProgressIndicator();
}
// after all data is sent do full reload
App.ViewModel.LoadMore = true;
App.ViewModel.ShowButton = false;
ApplicationBl<Transaction>.GetDataLoadingCompleted += OnTransactionsRefreshCompleted;
ApplicationBl<Transaction>.GetData(0, 10);
_progress.Show();
}
OnTransactionRefreshCompleted we delete all transaction data in local database and get the latest 10 transactions. We don't need all the data, and this way user have synced data. He can always load more data by taping load more at the end of transaction list. It's something similar like those twitter apps.
private void OnTransactionsRefreshCompleted(object entities)
{
if (entities is IList<Transaction>)
{
// save transactions
var transactions = (IList<Transaction>)entities;
DatabaseBl.TruncateTable<Transaction>();
DatabaseBl.Save(transactions);
((MainViewModel) DataContext).Transactions.Clear();
//reset offset
_offset = 1;
//update list with new transactions
App.ViewModel.LoadDataForTransactions(transactions);
App.ViewModel.LoadMore = false;
App.ViewModel.ShowButton = true;
}
if (entities == null)
{
App.ViewModel.ShowButton = false;
App.ViewModel.LoadMore = false;
}
// hide progress
_progress.Hide();
// remove event handler
ApplicationBl<Transaction>.GetDataLoadingCompleted -= OnTransactionsRefreshCompleted;
}
Caveat - I haven't tried this with windows phone development but use of GUID identities is something I usually do when faced with similar situations - eg creating records when I only have a one-way connection to the database - such as via a message bus or queue.
It works fine, albeit with a minor penalty in record sizes, and can also cause less performant indexes. I suggest you just give it a shot.
I'm working with the Beta 2 version of Visual Studio 2010 to get some advanced learning using WF4. I've been working with the SqlTracking Sample in the WF_WCF_Samples SDK, and have gotten a pretty good understanding of how to emit and store tracking data in a SQL Database, but haven't seen anything on how to query the data when needed. Does anyone know if there are any .Net classes that are to be used for querying the tracking data, and if so are there any known samples, tutorials, or articles that describe how to query the tracking data?
According to Matt Winkler, from the Microsoft WF4 Team, there isn't any built in API for querying the tracking data, the developer must write his/her own.
These can help:

Old question, I know, but there is actually a more or less official API in AppFabric: Windows Server AppFabric Class Library
You'll have to find the actual DLL's in %SystemRoot%\AppFabric (after installing AppFabric, of course). Pretty weird place to put it.
The key classes to look are at are SqlInstanceQueryProvider, InstanceQueryExecuteArgs. The query API is asynchronous and can be used something like this (C#):
public InstanceInfo GetWorkflowInstanceInformation(Guid workflowInstanceId, string connectionString)
{
var instanceQueryProvider = new SqlInstanceQueryProvider();
// Connection string to the instance store needs to be set like this:
var parameters = new NameValueCollection()
{
{"connectionString", connectionString}
};
instanceQueryProvider.Initialize("Provider", parameters);
var queryArgs = new InstanceQueryExecuteArgs()
{
InstanceId = new List<Guid>() { workflowInstanceId }
};
// Total ruin the asynchronous advantages and use a Mutex to lock on.
var waitEvent = new ManualResetEvent(false);
IEnumerable<InstanceInfo> retrievedInstanceInfos = null;
var query = instanceQueryProvider.CreateInstanceQuery();
query.BeginExecuteQuery(
queryArgs,
TimeSpan.FromSeconds(10),
ar =>
{
lock (synchronizer)
{
retrievedInstanceInfos = query.EndExecuteQuery(ar).ToList();
}
waitEvent.Set();
},
null);
var waitResult = waitEvent.WaitOne(5000);
if (waitResult)
{
List<InstanceInfo> instances = null;
lock (synchronizer)
{
if (retrievedInstanceInfos != null)
{
instances = retrievedInstanceInfos.ToList();
}
}
if (instances != null)
{
if (instances.Count() == 1)
{
return instances.Single();
}
if (!instances.Any())
{
Log.Warning("Request for non-existing WorkflowInstanceInfo: {0}.", workflowInstanceId);
return null;
}
Log.Error("More than one(!) WorkflowInstanceInfo for id: {0}.", workflowInstanceId);
}
}
Log.Error("Time out retrieving information for id: {0}.", workflowInstanceId);
return null;
}
And just to clarify - this does NOT give you access to the tracking data, which are stored in the Monitoring Database. This API is only for the Persistence Database.
