ASO datacopy between scenarios

Hi,

I am trying to copy data from Actual scenario to Budget Scenario in ASO application on  essbase version 11.1.2.4 using below MaxL:

execute calculation on database ASOAPP.ASODB with local script_file "F:\script.csc"

POV "Crossjoin(****)"

SourceRegion "{[Actual]}";

script.csc contains :

[Budget] := [Actual];

I am getting below error message:

Statement executed with warnings.

Server request Fails with error code [1040023]

Custom Calculation terminated with Essbase error 1013295

Any help is greatly appreciated!

Thanks,

Taiyab
