I'm in problems with Spotfire. I have filtered my dataset by feature (dat_delivery) and I would like to make de difference between rows with the same dateprice. I know that spotfire have the difference aggregation method but it doesn't work. (I'm a Rookie)
Any idea?
Thanks
I agree with Mickael M. that more information is needed to get an answer to this question, but I just want to note that you said, "I have filtered my data." When you create a calculated column, Spotfire will take all of your data into account, not just the filtered data. Sometimes this is a big deal and sometimes not.
If you want to calculate only on filtered data, you will need to write an expression on the axis of a visualization, not create a calculated column.

Is there a way to move imported columns after calculated columns? I know I can create a new table by using Selectcolumns, but that'll just balloon the size of the PowerBI data file. Seems like such a miss on Microsoft's part
No there is no way to. I would avoid calculated columns and instead create the additional columns in Power Query which will eliminate your problem anyway.
Simply start all calculated columns with an underscore (judging by your username, you seem to be fond of unnecessary underscores)
Another option would be to put imported and calculated columns into different Display folders (such a miss on user's part)
I don't know if I even worded the question correctly, but I'm trying to create a measure that depends on what is showing in the pivot table (using PowerPivot). In the image I posted, "DealMonth" is an expression in the PowerQuery table itself that simply takes the start date of the employee and subtracts it from the month a deal was closed in. That will show how long it took for that salesperson to close the deal. "TenureMonths" is also an expression in the PowerQuery table that calculates the tenure of the person. The values populating this screenshot are coming from a total headcount measure created. What I'm trying to do is create a separate measure that will show when the "TenureMonths" is less than the "DealMonth." So if the TenureMonths is 5, then after DealMonth of 5, the value would be 0. Is this possible?
Screenshot
I should add the following information.
"DealMonth" - Comes from the FactData table
"TenureMonths" - Comes from the DimSalesStart table
These two tables are joined by name. I feel like I'm so close because I can see what I want. The second image below is a copy/paste of the pivot table result but with my edits to show what I'd want to have shown. Basically, if(TenureMonths >= DealMonth,1,0). The trouble seems to be that since they're in two different tables, I can't make it work. The rows in the fact table are transactions, but the rows in the dim table are just the people with their start and end dates.
Desired Result
This is possible with some IF([measure1]<[measure2],blank(),[measure1]), however without seeing more of the data it will be hard to guide you specifically.
However you need to create two separate measures, one for TenureMonths and one for DealMonth, depending on the data this can be done with an aggregator forumla such as sum, min, max, etc (depends if there will be more than one value).
Then reference those two measures in the formula pattern I mentioned above, and that should give you want you want.
I figured out a solution. I added a dimension table for DealMonth itself and joined to my fact table. That allowed me to do the formulas that I needed.

In Batch!F3:G, I'm attempting to break down the data input from columns B3:C to their components (and eventually materials/minerals in I3:J) by using filter to compare results in Engine!P:R. Multiplied of course by the total number of each finished product I need.
I've been trying to figure out ways to arrayformula this together, and even tried quite a few query functions without success. The best I've been able to come up with is to string the actual formula together, appending them with {}, but this gets bloated quickly. I need this to be open ended because I have a tendency to build a lot of things at once. Any help would be appreciated, even just point me in the right direction!
Well, based on my limited knowledge about google sheet, I can only think of one way to do this automatically.
Here's a sheet I constructed based on your sheet.
https://docs.google.com/spreadsheets/d/1AfX8o05gUGPiN5S90w4o0yxuIYjsJRaXsaYUFTJuEPo/edit?usp=sharing
First, on Engine sheet, add one more column which will give you the number of materials required for that part, which is looked up in the PART LIST of BATCH sheet. For this I use VLOOKUP, as you see in D2.
Then on BATCH sheet, query the materials that VLOOKUP return positive, multiply it by the amount of item and then sum them.
This is done by the QUERY used in F3
This method only if you don't have duplicate item in your PART LIST, due to the way VLOOKUP work.
Of course if you want to break the material list further, you can do the same approach..
newparts_calc
if (([MonthToDateQuery].[G/L Account] = 4200 and [Query1].[G_L_Group] = 'NEW')) THEN ([Credit Amount]-[Debit Amount]) ELSE (0)
Data Item1
total([newparts_calc])
I need Data Item1 to return newparts_calc values only.
So for example in 1st row Data Item1 should be 8,540.8, but is 34,163.2
Whats wrong? how do i fix?
REVISED QUESTION
I apologize for not making sense on the original question.
I have many of the calc's that im trying to gather and put on a crosstab. I want to see sales by month (row) and part category (column)
[Query2] is the one shown in picture above.
It joins [MonthToDateQuery] AND [Query1]
The join is on 'Invoice' and carnality is 1..1 = 1..1
[MonthToDateQuery] is based on the package im working in. General ledger. It supplies the g/l entries for each sales g/l account
[Query1] is a SQL query i brought in to be able to break out categories even further from g/l group.
For example g/l account 4300 is rebuilt. However i needed to break out even further to see Rebuilt-Production and Rebuilt-New. I can do that with the g/l group.
I saw in my g/l account ledger entries that it referenced the invoice number. So thats how i tied in my SQL.
So as you can see from the table below (which is the view tabular data from query) i need a total. I have tried plugging newparts_calc into my crosstab and setting aggregation to total but the numbers still dont seem right. I dont think i have something set as it should be.
All the calc's im doing are based on single or multiple G/L Accounts and single or multiple G/L Groups.
Any Advice?
As you can see the problem seems to be duplicate invoice numbers.
How can i fix?
Couple things come to mind:
-Set the processing order to 2
-Since your calc is always a multiple and you are joining two queries, you may need to check your cardinality. Sometimes it helps to add derived queries to ensure you are working with the correct grain.
I'm obviously missing something, but if you want
I need Data Item1 to return newparts_calc values only.
just use newparts_calc, without total? That would give you proper value for row 1 -)
If you need a running-total for days (sum of values for previous days) — you should use a running_total function.
At a guess, one of your two queries is returning multiple rows for each invoice, which will cause this double counting. Look at the output of the two queries and see if that's happening. If so, then you just need to work out how to collapse that down to one row per invoice.
Per your new question - The underlying data has got to be causing the issue. Its clearly not 1:1 (note that even though this is what your stated cardinality is, Cognos does not enforce 1:1). Invoice number is not unique, GL Group is at a lower level.
To improve my skills on Hector and cassandra I'm trying diffrent methods to query data out of cassandra.
Currently I'm trying to make a simple message system. I would like to get the posted messages in chronological order with the last posted message first.
In plain sql it is possible to use 'order by'. I know it is possible if you use the OrderPreservingPartitioner but this partioner is deprecated and less-efficient than the RandomPartioner. I thought of creating an index on a secondary column with a timestamp als value, but I can't figure out how to obtain the data. I'm sure that I have to use at least two queries.
My column Family looks like this:
create column family messages
with comparator = UTF8Type
and key_validation_class=LongType
and compression_options =
{sstable_compression:SnappyCompressor, chunk_length_kb:64}
and column_metadata = [
{column_name: message, validation_class: UTF8Type}
{column_name: index, validation_class: DateType, index_type: KEYS}
];
I'm not sure if I should use DataType or long for the index column, but I think that's not important for this question.
So how can I get the data sorted? If possible I like to know hows its done white the CQL syntax and whitout.
Thanks in advance.
I don't think there's a completely simple way to do this when using RandomPartitioner.
The columns within each row are stored in sorted order automatically, so you could store each message as a column, keyed on timestamp.
Pretty soon, of course, your row would grow large. So you would need to divide up the messages into rows (by day, hour or minute, etc) and your client would need to work out which rows (time periods) to access.
