Deleting personnel no.

Hi Friends,

I have a prob. deleting personnel no. It shows the message that Personnel no. accounted. When I chk 0003, it is showing accounted to 28.02. 2007. & PDC recalculation as 01.01.2007 (Both boxes disabled)

But when I tried to delete FI posting, this personnel no. is not available in TC pcp0.

Can anyone tell me the reason & how to delete this no.

Regards
