SNP planned order deleted in APO, but not in R/3.

OK Guru's,

We have a situation where during the weekend SNP planning runs, SNP Planned orders are deleted in APO, but the order is never deleted in R/3.  The change pointer is not in CPP and there are no failed queues.  Also, when you run CCR on planned orders, we will get an error on some orders saying "Not in APO" and the only option to reconcile that order is to "Send to APO".  The option that should exist is "delete in R/3" becuase the deletion never occured in R/3.

If you send the order back to APO, the order will show in the "Production Confirmed" line of the Planning Book.  This is because APO is thinking that this order is an order that was created in R/3 when in fact is it really is a SNP planned order.

Any clues to why this would happen?

thanks,

Brian
