How to copy data from different version using data actions in SAC with specific condition?

Hi,

Here is the scenario. I want to copy data from source version to target version. There is a condition if version "A" then I need to copy from " A" from previous year but if the version is "B" then I need to copy from current year from "B" to my private version. Please refer below is the screenshot.

I have defined "X" as Version parameter but I'm not able to compare "X" with the version dimension using IF statement in data action.

Anyone who has faced similar kind of issue or knows the workaround in this case. Their comments would be deeply apprecaited.

Thaks.
