HR Rules: PPPAR A

Dear Gurus,

I'm facing a problem, and you may know how to help me.

I have a rule that must need to verify if there is a leave (partial period) in the processing month. I found the command PPPAR A and I think it should fit, but it's not working.... can you please help me?

My rule is:

PPPAR A

*

GCY ZEX1

A

GCY ZEX3 --> If there is a leave it should run rule ZEX3 instead off ZEX1.

I though this command should work fine like this, but the system is always considering rule ZEX1 even if there is a leave in the processing month.

Can you please help me?

Regards,

PC
