Difference between CAT2 and CN27 confirmation in AFRU table

Hi Experts,

I have noticed a scenario and wanted to understand if its standard.

When I confirm hrs on a network activity via CAT2 using an employee id, the field for sender cost center and controlling area is populated for the confirmation in AFRU table.

However when I confirm hrs on network activity via CN27/CN41, I don't see the Sender cost center and Controlling area fields populated in the AFRU table.

In both cases though, I see hours in AFRU and cost updated in CJI3.

Is it standard that Sender cost center and controlling area is blank in AFRU table for confirmations done via CN27? if so why?

Thanks for your time.

Regards,

Krishna
