Macro: Periods shift in DP planning book

Hello together,

I have a marco question. I want to execute a periods shift with the help of a macro. A condition in the planning book is that the planning bucket profile. The planning book profile contains weeks and months.

Function Macro:

The macro should shift a value one period in the past . But the macro doesn't work.

Remark: The macro only works if the planning bucket profile contains only weeks or months.

Question: Is it possible to execute a periods shift if the planning bucket profile contains weeks and months?

Thanks in advance for your help.

Kind regards.

Christian
