I'm with a prblema I hope eplicar clearly.
I have a dw with varis facts and all the facts has several fields in common, one of these fields is the month_id.
I make the burden of these facts in my power bi application and then concatenate all to become one fact only.
the problem is when I do some filters, as reported not all facts have the same fields with month_id and when I filter a month has indicators that due to have a field of a fact that had not month_id the indicator in question is null, I tried to add the month_id in all facts before concatenate however is not possible.
Any suggestions how to solve this?
