Hi @josetabuenca ,

Please try this one:

CATEGORY =
COALESCE (
    MAXX (
        FILTER ( 'Table2', 'Table2'[ID] = EARLIER ( Table1[ID] ) ),
        'Table2'[CATEGORY]
    ),
    "N/A"
)

Hi @v-yanjiang-msft 

 

Thanks a lot for your support.

 

I am obtainining same error message than before

 

The column 'Table1'[CATEGORY] cannot be pushed to the remote data source and cannot be used in this scenario.

 

Guessing here that Table1 stored in Direct Query is having an effect here.

Hi @josetabuenca ,

According to your description, here's my solution.

Add a calculated column in Table1:

CATEGORY =
COALESCE (
    LOOKUPVALUE ( 'Table2'[CATEGORY], 'Table2'[ID], 'Table1'[ID] ),
    "N/A"
)

It has no matter with the relationship, get the correct result:

@josetabuenca , if relation between table 2 and table 1 is 1 to Many

 

then yoy can try

 

related(Table2[CATEGORY])

 

or

 

coalesce(related(Table2[CATEGORY]) , "N/A")

Hi

 

Thanks for your swift reply.

 

The relationship between Table 2 and Table 1 is Many to 1.

I cannot change the relation to 1 to Many. I got following error message: The cardinality selected isn't valid for this relationship.

 

Some another idea here?

 

Regards

@amitchandak 

I have been able to change the relation to 1 to Many by data cleaning ID column in Table 2 (remove duplicates and remove nulls),

However solution is still not working, I am obtaining following error message

 

The column 'Table1[CATEGORY]' either doesn't exist or doesn't have a relationship to any table available in the current context.

 

There us a relationship 1 to many between Table 2 and Table 1.

 

Some idea here?

correction

 

error message is The column 'Table2[CATEGORY]' either doesn't exist or doesn't have a relationship to any table available in the current context.
