Create a Calculated Column from Different Tables

[Anonymous]

Hi,

I have two table (alot more but ill use two).

In my ad details table 'addetails' I have a column called 'adqinstr' in there I have mulitple rows with either "Private", "Trade", or "Bus Acc".

In my customer table 'custAcc'  I have created a cacluated column where i want to say if find "Buss  Acc" then set it to "BA" else put "normal".

None of the DAX functions seem to be available (no list appears) and the useful columns only seem to show the columns for that table.

Thanks

According to the table relationship shortcut you provided above, there is a One to Many relationship between table "custAcc" ant table "adDetails", and table "custAcc" is on the one side of the relationship. In this scenario, you should use RELATEDTABLE function to create the calculated column for table "custAcc".

The formula below is for your reference.

Column =
IF (
    CONTAINS ( RELATEDTABLE ( adDetails ), adDetails[adqinstr], "Bus Acc" ),
    "BA",
    "Normal"
)

Hi There,

You can create the conditional column in Query mode.

Hi Bhavesh,

I have tried but it does not seem to give me the option to reference the other table.

Thanks

Sort of like 

Column = If(Related('adDetails'[adqinstr])="Bus Acc","BA","Normal")

But it doesnt work

Can you please share your data model?

Thanks

Hi There,

Instead of relying on calculated column, why don't you try merging both the tables and It can give you desire results.

Since your data model appears to have relationships all over, can't you instead use DAX to make your calculated column instead of Power Query (M)?

To make a DAX calculated column right click the table you want to create the column in and click "New Calculated Column"

Hi Wonga,

Ive tried to use 

Column = If(Related('adDetails'[adqinstr])="Bus Acc","BA","Normal")

But it does not seem to like it ....struggling with the DAX.

Thanks

@Anonymous When you say it doesn't seem to like it, can you expand on that? What is the exact error message?

The column 'adDetails[adqinstr]' either doesn't exist or doesn't have a relationship to any table available in the current context.
