Filter Calendar lookup table based on fact table value

[EnderWiggin]

Hi All,

I would like to ask your help to find a solution of the following case.

I would like to get the minimum Calandar[Date] value which is equal or greater than TransctionPast[FirstValid] date.

Here are the relationships:

I created the following measure but it just uses a lot of RAM without any result, when I tried to put it in it in a power pivot's value section

I think it is caused by the relationship and the filter direction but I can not figure out how to get the required date value. 

I would use it for further calcualtion which will be in the value section of a power pivot.

Could you help me to define the required measure? Please see the sample file on the following link. Thank you very much in advance!

@Anonymous, you are right in some cases the 'TransactionPast'),[FirstValid]) value was not available becasue of the filter context, so this was the root cause of the high memory usage. Your measure works, so thank you very much  for the solution and your response!

You would not return anything if you compare Date with MIN('TransactionPast'),[FirstValid]). If you would to compare Calendar date with minimum date in [FirstValid] column.

Try:

Measure = CALCULATE(MIN('Calendar'[Date]),FILTER('Calendar',[Date]>=MINX(ALL('TransactionPast'),[FirstValid])))
