I have consulted this question - OBIEE Moving Average (Mavg) for 4 weeks on Pivot Table - in order to understand how to do a moving average in OBIEE. However, I am having trouble calculating that item in a pivot table.
In the pivot table view I thought I would just select New Calculated Item and create my moving average function for the pivoted values. Yet, in the "Values From" drop down menu the items I want to average are not present. I believe this may be because they are not extracted data values but previously calculated values from the data (in the original table's columns). I tried selecting "treat as attribute column" but this failed as well. How can I created a moving average within the pivot table for a column that was calculated from the original data?
Looks similar to this:
Pivot Table
ID Value
01 45
02 54
03 65
... ...
Where Value is Amount Sold / Days. And both Amount Sold and Days are stored in the original data table.
Go to the criteria tab and pull in a measure (any measure will do). Now edit that measure's column formula to your formula of Amount Sold / Days. I would rename it as well.
When you click over to the results tab, you will see that column added to all views. Just edit each view and remove the column from the views you do not want to see it in. You can also replace your existing value column in your pivot table (if it was present) with this new calculated column.
Pivot table calculated items are typically used in conjunction with columns that are already in the pivot table.

I have Table 1. It is filled with dates a inspection is going on. Plumbing or Garden inspections for example.
Table 2 links to these appointments and has additional columns with details such as a Person assigned to the inspection, and what property the inspection is at. I need these two tables to be separate as described, and they are linked by a simple ID column.
Is it possible at all to add a column to Table 2 called 'Last Date of Plumbing Inspection'. The idea is for any given Property in Table 2, there can be multiple inspection entries in Table 1 for it. The point of this column is that it should look in Table 1, find the matching ID, find the latest inspection date out of all the Plumbing-related inspections, and then set the column value to that.
The problem I am having with this is it seems like calculated columns can ONLY implement logic using the columns of the table the calculated column was created in. In Table 2, I can't create a calculated column that interacts with Table 1 at all. I could create a look up column, but I can't combine calculated columns with look up columns. Is there a way to build this latest inspection date column without too much complexity?
Actually you can create a Rollup field and put a MAX aggregate function for achieving your requirement from related table. Read more
I have a Dashboard with different visuals.
Data is made up of different values for insurance companies.
I want my slicers/filters to not filter all data, but to only highlight the chosen company.
For example, in my slicer I choose the insurance ABN.
Instead of showing me the value for ABN only in my visuals, I want all other values to still be visible and ABN's value to be highlighted in the visuals.
Does anyone know how to do this?
You can use conditional formatting to achieve this. Lets say that we will change the background color to "highlight" a row (or cells, to be precise).
First, we need a slicer, which will not filter our data. We can do this by duplicating our source table, removing the unnecessary columns and making sure there is no relationship between the source and the duplicate. So if we have a source table, named Table, like this:
Right click on it and select Duplicate:
Then right click the title of the column you want to keep and select Remove Other Columns to get a list of company names only (you may also remove the duplicates, but it's not required). Then in the model delete the relation between both tables:
Now you can place a table showing company name and sales from your data source, and a slicer for company name from the duplicate table. At this point selecting values in the slicer should not affect the table.
Now you need to capture the value of the slicer and use it in a measure, which will determine should current row be highlighted or not. You can use SELECTEDVALUE for that, but note that it will give you a value only if there is a one selected in the slicer. If you want to support highlighting of more than one company, it gets a bit more complicated.
Make a new measure in your source table, like this:
Measure = IF(HASONEVALUE('Table (2)'[Company name]);
IF(SELECTEDVALUE('Table (2)'[Company name]) = MAX('Table'[Company name]); 1; 0);
IF(ISFILTERED('Table (2)'[Company name]) && COUNTROWS(FILTER('Table (2)'; 'Table (2)'[Company name] = MAX('Table'[Company name]))); 1; 0))
In case there is only one value selected in the slicer (see HASONEVALUE), then our measure will return 1 (highlight) or 0 (don't), comparing it with the current row.
Otherwise (i.e. there is no selection in the slicer, or there are 2 or more companies selected), then we will look at the filtered list of companies (Table (2)) - if it contains current row, then 1 (highlight), otherwise 0 (don't). But we will also handle the case, where there is no value selected in the slicer. In this case the list will contain all the companies, i.e. all rows will be highlighted. Here comes ISFILTERED. And at the end, if the list is filtered and current row exists in the filtered list, then 1 (highlight), otherwise 0 (don't).
Now, you need to use this measure to change the background of the column - right click each column in your table and select Conditional formatting -> Background color:
Then format by rules, where Measure >= 1 like this:
Now, when there is no selection in the slicer, there are no rows highlighted in the table:
If you select one company, it is highlighted:
It also work if there are multiple companies selected:
Thank you Andrey for your step-by-step explanation which as been incredible helpful. I'd like to follow up with a further question, particularly regarding the comment below.
"You can use SELECTEDVALUE for that, but note that it will give you a
value only if there is a one selected in the slicer. If you want to
support highlighting of more than one company, it gets a bit more
complicated."
In my model, I've linked a third table (Table (3)) to Table (2) with a many to one relationship with Table (2). Therefore when I click on Table (3), it will filter Table (2), which acts as a slicer for Table (1).
When only 1 value is filtered in Table (2), it conditionally formats the cells in Table (1). However, when more than 1 value is filtered in Table (2), conditional formatting fails.
As I'm looking to avoid manually selecting multiple values in the slicer (Table (2)), I was wondering if there's a workaround for SELECTEDVALUE such that it is able to conditionally format when I filter more than 1 value in Table (2).
Context:
I have a data set for the weights of truck and trailer combinations coming into my site over the span of a few years. I have organized my data by seasons as I am trying to prove that the truck:trailers in winter are noticeably heavier due to ice, snow, and mud. The theory is, if the tare weight is higher in this season (the weight of the truck after it empties its load) than its Avg tare weight (which I need to calculate from the data) it can be deduced that the truck:trailer combinations are coming in with extra weight that we pay for in part as some snow/ice/mud falls off in the trailer emptying process.
What I've done so far:
I've defined a custom date range for my seasons
I've grouped Truck:Trailer by: count to get a duplicates column and, all rows to keep all my details
I've filtered out every combination I've seen less than 50 times, as i want good representation for each truck:trailer combo so that I can better emphasize repeated patterns
I've added an index column to better keep track of the individuals before expanding the details
What I need to do:
I only want to work with truck:trailer combinations which have weighed in for all four seasons at least once
I need to find the average tare weight of the truck:trailer combinations based over the extended range for both summer and autumn (the dry time of the year) while preserving the raw tare data for all seasons, as I need to eventually compare the winter tare values to this average.
example of my data
When I'm finished I'd like the data to look something like this
Pivot Chart
query data
For your first question (all seasons) you can add a column that holds the distinct count of the values in [Season] for each [Driver:Trailer]. Then filter your table on that column, keeping only the 4's. To achieve this, add the following m-code to your script in the Advanced Editor. Change the part after in to #"DistinctCount Season"
#"DistinctCount Season" = Table.Join(#"insert name previous step","Driver:Trailer",
Table.Group(#"insert name previous step", {"Driver:Trailer"},
{{"DistinctCountSeasons", each Table.RowCount(Table.Distinct(_,"Season")),
type number}}),"Driver:Trailer")
Insert the name of your previous step where indicated.
For second question:
You can use a matrix-visual for that in you report. First create a measure:
[AverageTare] = AVERAGE(table'[Tare])
Then put [Season] on Rows and the [AverageTare] on Values. You can create a group (right-click on [Season] in the FIELDS-pain) called [DrySeason], to combine the values for Spring and Summer.
If that doesn't work for you, explore the AVERAGEX function.
EDIT
In excel you can use a pivottable. Put [Season] on Rows and the [AverageTare] on Values. Right-click a value in the pivottable. Select Value Field Setting and choose Average. Then select the Seasons you want to group, right-click and select Group.
EDIT 2
To add a column in the Power Query Editor that holds the average [Tare] for the [Season] in each row, add the following steps to your script in the Avanced Editor:
#"GroupedSeasonAvg" = Table.Group(#"Insert name previous step", {"Season"}, {{"AVG", each List.Average([Tare]), type number}}),
#"JoinOnSeason" = Table.NestedJoin(#"Insert name previous step",{"Season"},GroupedSeasonAvg,{"Season"},"AVGGrouped"),
#"ExtractSeasonAVG" = Table.ExpandTableColumn(JoinOnSeason, "AVGGrouped", {"AVG"}, {"SeasonAVG"})
It works something like this:
"GroupedSeasonAvg" : Creates a table with the avereges for each [Season]
"JoinOnSeason": Creates a new column with tables joining the [Season] value for each row to [Season] in the grouped table.
#"ExtractSeasonAVG": Expand each table and keep only [AVG].
I have two tables in PowerBI. One called 'Fact_WorstInstance' contains rows of (Index,Instance). For example:
1,2
2,1
3,2
One called 'Fact_AllInstances' contains rows of (Index,Instance,Value). For example:
1,1,'Red'
1,2,'Green'
2,1,'Amber'
2,2,'Red'
2,3,'Brown'
3,1,'Green'
3,2,'Blue'
The first table is essentially a pointer to the worst entry in the second table for the given index (as categorised by some external system).
There is a slicer on which Indexes are visible to the user.
What I want to do is find the worst instance value for the highest visible Index in the 'Fact_WorstInstance' table, and then get all the Index and Value rows from the 'Fact_AllInstances' table for that Instance.
For example, if the slicer isnt filtering then (3,2) should be the active row from from the 'Fact_WorstInstance' table and this should be used to get Instance 2 from the 'Fact_AllInstances' table
1,2,'Green'
2,2,'Red'
3,2,'Blue'
from the 'Fact_AllInstances' table.
I tried to do this in many different ways, by creating a measure on the 'Fact_WorstInstance' which gives the highest visible row. And then use this measure to create a calculated column on the 'Fact_AllInstances', with 1 for worst and 0 for not worst. And then use this calculated column as a filter in PowerBI.
The measure itself gives the expected value. The problem I have is when the measure is used to create the calculated column, I cannot find a way to stop the Index being filtered based on the row of calculated column - and therefore the measure outcome changes for each row.
My measure:
Worst Entry = CALCULATE(FIRSTNONBLANK(Fact_WorstInstance[Instance],1),filter(ALLSELECTED(Fact_WorstInstance),Fact_WorstInstance[Index]=MAX(Fact_WorstInstance[Index])))
My column:
WorstColumn = if(Fact_AllInstances[Instance]=[Worst Entry],1,0)
So instead of getting the output above, I get
1,2,'Green'
2,1,'Amber' --> because for Index 2, the measure gives index 1 as worst
3,2,'Blue'
This is a possible solution you might want to implement.
First of all, calculated columns are not affected by slicers/page filters, you will need to create a measure for that, so the way your are appraching the problem won't work.
Create an additional calculated table that holds unique instances values. In Power BI, Modeling tab there is a icon for creating a New Table, where you can use an expression to produce the table.
Use this expression:
IsntancesCalcTable = VALUES(Fact_WorstInstance[Instance])
Now you have a table called InstancesCalcTable in your model.
Drag the Instance column in the InstancesCalcTable and drop it in the Instance column of the Fact_WorstInstance, this will create a relationship between InstancesCalcTable and Fact_WorstInstance via Instance. A line between both tables will be drawn in the Relationships view, double click that line and you will see the Edit Relationship window.
Make sure it looks like this:
Then do the same for creating the relationship between InstancesCalcTable and Fact_AllInstances.
You will end with a model like this:
Then you can use Index column in the Fact_WorstInstance table, in a slicer and it will filter the Fact_AllInstances table to get only the instances selected.
However if you don't have any filter all rows in Fact_AllInstances will be shown.
I have a table in Tableau that is based on a MTD calculation. It gives multiple values for different departs on each day of the month. This table is linked to another sheet that I click on to choose the value in the table that I want to see.
Right now I only highlight that value in the table. I want to be able to pull one specific value out and display by itself in the dashboard close to the chart.
How do you pull a value from a table and display.
