Defaulting Payroll Area in Organisational Assignment ( Infotype 0001 )

We defined the feature ABKRS such that , if MOLGA = 10 and PERSG = 1 and BTRTL = 1400 and PERSK = UB then ABKRS = xx.

When we perform an action, for EE status change, it doesn't default the payroll area to what we set, but populates with a different value.

Any idea why this is happening ? Is there a config somewhere else that controls what value of payroll area should be populated ?

Thanks,

Swarna.
