Helper II

## create new column or measure using Coalesce on two different tables

Hi I have a fact table say fact1 and two dim tables dim1 and dim2 both dimension tables are joined with fact table using their dimid.

I need to create a calculated column or measure like if ( dim1.dimid=-1) then dim2.name else dim1.name

I will prefer this new column in fact table, but it can be anywhere.

Thanks

Could you tell me if your problem has been solved? If it is, kindly Accept it as the solution. More people will benefit from it. Or you are still confused about it, please provide me with more details about your table and your problem or share me with your pbix file from your Onedrive for Business.

Hi @RG007 ,

You could merge these three tables and then use the following formula:

``````Measure =
IF (
MAX ( 'Merge1'[DimID] ) = -1,
MAX ( 'Merge1'[Dim2.Name] ),
MAX ( 'Merge1'[Dim1.Name] )
)``````

Or you could creata a new calculated table

``````Calculated Table =
SUMMARIZE (
'Fact',
'Fact'[Index],
'Fact'[DimID],
"Name", IF ( MAX ( 'Fact'[DimID] ) = -1, MAX ( 'Dim2'[Name] ), MAX ( 'Dim1'[Name] ) )
)``````

Here is the pbix file.

@RG007 , Try a new measure like .

if(max(dim1[dimid])=-1, max(dim2[name]) , max(dim1[name]))

A column is only possible if there are have some kind of relation
