Hi, aggr does an expression for each value of a dimension(s), so you need the expression and at least one dimension.

Thanks, but i have no idea for this calculation

In the screen capture there are two parenthesys in orange, one starts the aggr() and the other closes it, so you have to options:

- Remove Aggr()

- Add a dimension before closing the parenthesys, it looks like the dimension could be [Customer Key] or something that groups different [Customer Key]

i removed the aggr(), it doesn't work

[Or]

The aggr() is still there, right on the top line... the inner one probably wasn't the problem.

That's not the aggr to remove, I said the one with parenthesys in orange in your first screen capture

Thanks ! it is working. I only add the customer key at the end of the aggr()!!

Thanks a loooot!!!!!

Try with option 2: add the dimension to aggr. Also maybe there is somenting in the _customerRepeat12Months variable
