Count if date is earlier than a date in related table

Hi,

 

Trying to count the number of CarerRef if the StartDate  was before the date in a related table.

 

Trying -> Count Carer Ref = CALCULATE(COUNTROWS(CarersList),CarersList[CarerRef],CarersList[StartDate] < RELATEDTABLE(vw_ShiftsAll),vw_ShiftsAll[iDate])

 

Getting error The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value.

 

Any ideas what I need to change?

Hi @android1

 

Please give this calculated column a go.

 

Column = 
    CALCULATE(
        COUNTROWS('vw_ShiftsAll'),
        'vw_ShiftsAll'[iDate] > EARLIER('CarersList'[StartDate])
        )

Hi @android1

 

Do you want this to be a calculated column or calculated measure?

 

Which table is on the One side of the one-to-many relationship between 'CarersList' and 'vw_ShiftsAll' ?

Hi @Phil_Seamark,

 

I'd like it as a calculated measure. Here's my relationship.Relship.png
