Issue with function DATACOPY on demand rule

Content

 

Hi, I'm trying to insert the DATACOPY function in my on demand rule.
Whichever way I set it, it always returns the same errors:
Cannot use restricted dimensions: "YEARS"

or

Cannot use restricted dimensions: "SCENARIO"

or

Cannot use restricted dimensions: "PERIOD"

I should actually use it to copy from one scenario to another.
Are there any rules I need to follow?

 

Regards,

Alberto
