Can I use an IF in this Calc Mgr Rule?

Hello,

We are using Calculation Manager 11.1.2.4.013.

We have a Calc Manager rule that copies data from one scenario/version/year to another. We never anticipated that the rule would be used to copy within the same scenario/version, but we are now trying to do that.

The following code snippet works when source/target scenario/version are different, but fails when the source and target are the same.

FIX("No Year", "BegBalance")

    DATACOPY {RTP_Source_Scenario}->{RTP_Source_Version} TO  {RTP_Target_Scenario}->{RTP_Target_Version};

ENDFIX

I am trying to put an IF statement around it, to only copy the data if the scenario or version has changed. I cannot get it to validate. Below is one of the examples I have tried.
