Reservation entry error


I using Microsoft dynamics NAV 2009 SP1 (NAV 6.0 SP1) , when i try to receive a PO the system show me this messeage

“The reservation entry does not exit”

Entry No. “# line number”, Positive = ‘NO’.

I review the reservation entry table and i look for that line … the line exist buen i dont know how can i fix it

The positive = No part leads me to believe that the items on the PO were once also reserved on a sales order.

It’s hard to say without knowing more though. Are you tracking all of your inventory by serials / lots?

Yes i tracking my inventory by lots
