Hi

I have taken entity dimension as a run time prompt value, so if a user can have the option of both running ruleset at "all branch" level (highest level) or running for all the branches at the same time.(level 0 branches)

and in my calculation script i have created as below, when i need to run for certain branches, except for few.

if(@ismbr(@REMOVE({RTP_Entity},@list("1101","1102","1127","1805","2801"))))

but due to this part of the script rule fails. im getting the below error. have anyone experienced this, and if so any solution.
