Duplicated records when adding Time Characteristics into infocube

Hi experts,

I created ZPA_C01 infocube copy from standard one, 0PA_C01 (HR - Headcount and Personnel Actions). I added the following time characteristics to ZPA_C01 infocube: 0FISCPER, 0FISCPER3 and 0FISCYEAR. I need them with reporting purposes.

Then I assign value to these new characteristics through a formula (or even forcing them to a constant value) in transformation rules between 0HR_PA_0 infosource and ZPA_C01 infocube.

When I run DTP in order to transfer info from PSA table to ZPA_C01 infocube, records get duplicated in data target as they are shown in the attached picture.

Can you please explain the behavior and how to solve the situation?

Thanks in advance.

Regards,

Juana
