I have a measure whereby I calculate some data based on a slicer value. The slicer determines which table I get my data from e.g. SUM(TableA[sales]) or SUM(TableB[sales]). (Each of my tables is of the same structure).
I'd like to be able to set up a variable to dynamically change (with my slicer) which table I'm referring to.
Right now I have:
// Set __table to a stored string representation of the name of the database
// This seems to work
VAR __table = SELECTEDVALUE( AllTables[TableNames] )
// Evaluate the sales column of my variable table
// This doesn't work due to 'Cannot find name sales'
CALCULATE(SUM(__table[sales]))
I guess what I'm after is a way to have the slicer change the referenced table in my measures (with all of the columns being the same for each table).
I'm new to Power BI and I've been struggling with this for several days now. I'd really appreciate any help with either the method I'm attempting or any alternatives.
If you have small amount of data in each table, you can merge them all together as they are in same structure. Just add an additional column with reference of the Table name. Now you can create your Slicer using the new column and it will hold all table names in the list. Now, if you change table name in the slicer, your visuals will show results based on data from that respected table.

I'm currently building a report in Power BI. I added a matrix table along with its data. The matrix table just consist of sums per column (shown below).
There are multiple of slicers I have for the report. The problem is when I start filtering, the data disappears from the matrix. Instead of disappearing, I want it those values to be zero.
I have already used the measure: IF(ISBLANK(SUM(COUNT)), 0, SUM(COUNT) And it still did not work (shown below). What should I do so that the zeroes would appear on the matrix table?
There are two things you need for this approach to work
You need your Categories in a separate table to the rest of your data (joined by category ID) - if you don't have an ID, you can get away with Category name). You can build this table in DAX with something like CategoryTable = DISTINCT(MyData[CategoryName]). This new table and your data table need to be linked with a relationship. On your visual, use the Category from the Categories table and the measure you have created.
Make sure "Show items with no data" is checked on the matrix's fields.
I have measure that store the Slicer selected value. now I want to store measure value in new table but not getting success. Please help here.
Also i want to know if there is a way to store slicer selected value in table directly.
below syntax i used to store slicer selected value in measure
Slicer_Value = selectedvalue(column)
Regards,

You cannot store a slicer selection in one of your model tables (either in a new calculated table or a calculated column on an existing table) since these are only calculated when your data is loaded or refreshed rather than every time you make a slicer selection.
However, it's highly likely that there is another way to do whatever it is you are ultimately trying to achieve by another method.
I want to create a second table from the first table using filters with dates and other variables as follows. How can I create this?
Following is the expected table and original table,
Go to Edit Queries. Lets say our base table is named RawData. Add a blank query and use this expression to copy your RawData table:
=RawData
The new table will be RawDataGrouped. Now select the new table and go to Home > Group By and use the following settings:
The result will be the following table. Note that I didnt use the exactly values you used to keep this sample at a miminum effort:
You also can now create a relationship between this two tables (by the Index column) to use cross filtering between them.
You could show the grouped data and use the relationship to display the RawDate in a subreport (or custom tooltip) for example.
I assume you are looking for a calculated table. Below is the workaround for the same,
In Query Editor you can create a duplicate table of the existing (Original) table and select the Date Filter -> Is Earliest option by clicking right corner of the Date column in new duplicate table. Now your table should contain only the rows which are having minimum date for the column.
Note: This table is dynamic and will give subsequent results based on data changes in the original table, but you to have refresh both the table.
Original Table:
Desired Table:
When I have added new column into it, post to refreshing dataset I have got below result (This implies, it is doing recalculation based on each data change in the original source)
New data entry:
Output:
My scenario is this: SalesValue have been entered for multiple sessions namely Lunch, Breakfast, dinner which is grouped by SessionKey in numbers. The same SalesValue repeats at times for 2 or more sessions for a given production plan date, based on MenuKey, RawMaterialKey and IngSFKey.
I need to use DAX query in Power BI to remove duplicated SalesValue based on ProductionPlanDate and SessionKey for a particular MenuKey in a given date.
I have attached the screenshot of a sample value range of SalesValue containing duplicate values for the same date across different sessions for your reference. For example, rows 7 and 14 have the same ProductionPlanDate, SessionKey, MenuKey, and SalesValue.
So you have a table with one "Grain" and you want to change the "Grain" by using a subset of the columns. Specifically you want only rows with distinct columns ProductionPlanDate, SessionKey, MenuKey and SalesValue
To do this in a DAX query you would use
evaluate
summarize
( 'table name'
, 'table name'[ProductionPlanDate]
, 'table name'[SessionKey]
, 'table name'[MenuKey]
, 'table name'[SalesValue]
)
You could provide this to create a calculated table or provide it to each measure that needs to work with this coarser grained data set.
However as it seems you are in Power BI the more appropriate place to do this would be to create your coarser grained table using Power Query (via the Edit Queries section of Power BI).
This is better than doing it in DAX as DAX is more tuned to analytics where Power Query is tuned to data transformation - and you want to do data transformation.
You can either keep the table that you have now alongside the new modified or replace it accordingly.
option A will just change your incoming table to have the new coarse grain.
option B will keep your original table and have the new grained table alongside it. Note that this will mean any Power BI visuals that you have created will need to be "rewired" to use the new table.
To do the transform in Power Query, the steps for both options are
Go to the Edit Queries area on PowerBI
Select the columns that you want to create the new Grain (i.e. ProductionPlanDate, SessionKey, MenuKey and SalesValue) by holding ctrl and clicking the column headers of each column in turn.
Right click on the column header for one of the selected columns and select "Remove Duplicates"
If you want option B, simply first copy the existing table by using "Reference" then do the same thing as follows:
Find your existing table on the left Queries section, r-click and click Reference
Rename the new table something appropriate
Apply the transform steps to the new table as above
Click Close & Apply and rewire any existing visuals that you need to use the new table
If you find you don't need your old table you can R-click on it in Power Query again and uncheck "Enable Load" so that PowerBI will not see it anymore.
I'm trying to figure out how to get a measure to adhere to the filter set by a slicer in Power BI.
My DAX query is: Block Time Cost = SUMX( FILTER(v_Invoice_Line_Items, v_Invoice_Line_Items[IV_Item_RecID]=9), v_Invoice_Line_Items[billable_ext_price_amount])
I know very, very little about DAX so my initial query may be way off base.
It calculates as I expect, but when filter with a date range silcer the value does not update as expected or at all.
I'm pulling my data from two views in the same database, v_Invoice and v_Data_Combined. I have a page level filter on the row Record_Description to limit the data to the types I'm looking for and the measure pulls it's data from rows in the v_Data_Combined view.
The rows in v_Invoice are below.
A sample copy is here.
and the rows for v_Data_Combined, if you click they will enlarge.
A sample copy is here.
I have no relations set between the views.
How can I have a measure adhere to slicer filters?
The slicer has to be on the same table as the measures you're filtering, or on a table related to that table. If your slicer is on a column in v_Invoice and your data is from v_Data_Combined - and the 2 tables are unrelated in Power BI, the slicer from one table will have no effect on the data from the other table.
Without sample data (which can be fake data), it's hard to make further recommendations.
However, if the two tables you have aren't really related to each other, then I would recommend exploring the possibility of "lookup" tables. E.g. if you have Company_Name in both tables, then you might add a 3rd table that is a unique list of companies (their name, address, etc). Then, when you want to slice by company you would slice on this 3rd table. That slicer will then filter both related tables (without having to have the tables related to each other).
