PAN Number Update

 Dear Experts,

We are updating 100 + vendors, whose PAN number are entered wrong, we are updating the same to PANNOTAVBL.  While updating the PAN number from the concurrent request program India - Pan number Update(1), getting error " this pan number is already assigned to the vendor'.

Please guide how we can update the PANNOTAVBL for all these vendors through concurrent program.

Regards
