Business Rule Issue in Planning

Question

Hi All,
I am working on a business rule and I ve tried doing it many ways but still unable to achieve the desired results. Please find the BR below:-
FIX(@CHILDREN("Vendor Expenses")
,{Scenario},@Relative("Year",0),"No VendorCategory")
{UPKVendor}
IF (@ISUDA({UPKVendor},Master))
{UPKMasterVendor}= @MEMBER(@CONCATENATE("V",@NAME({UPKVendor})));
{ToVersion}->@IDescendants({UPKMasterVendor}) = {FromVersion}->@IDescendants({UPKMasterVendor})
ELSE
{ToVersion}->{UPKVendor}={FromVersion}->{UPKVendor};
ENDIF
ENDFIX
Assumptions :-
{UPKVendor} is a runtime prompt of type "Member" who's value is initiated from the web form (Vendor Dimension which is tagged with UDA's to identify the type of project)
{UPKMasterVendor} is a runtime prompt of type "Member" who's value is constructed by concatenating "V" to the {UPKVendor}
{ToVersion} & {FromVersion} are runtime prompt's as well and the user can select the values for these prompts as part of the business rule.
Desired Results:-
IF A VENDOR IS A "MASTER" Vendor, WHICH IS IDENTIFIED USING THE UDA
THEN COPY THE UPKMASTERVENDOR AND IT's DESCENDANTS FROM THE ONE VERSION (FROMVersion) to ANOTHER VERSION (TOVersion)
For some reason, the calc manager is not formulating @IDescandants({UPKMasterVendor})
{ToVersion}->@IDescendants({UPKMasterVendor}) = {FromVersion}->@IDescendants({UPKMasterVendor})
Any help is greatly appreciated.
Thanks,

Hi,
The issue here is that you are trying to assign a member string in a variable on runtime which is not quite possible in Calc Script language. As discussed here number of times and once more quite recently, Calc Script does not support object type (including string) assignment. You can only assign numeric values to members and variables alike. You should try something like @Match function or If condition to achieve what you are doing. Another issue in your script is that you use @Descendants in an equation. You should use @Descendants to restrict the boundaries of your calculation (IF(@ISMBR..., FIX etc) but not in equations.
Just to give an idea, have a look at below sample:
IF (@ISUDA({UPKVendor},Master))
IF(@ISMBR(@Descendants((@MEMBER(@CONCATENATE("V",@NAME({UPKVendor})))))
{ToVersion}= {FromVersion};
ENDIF
ENDIF
Cheers,
