Inbound delivery serial number updation
I have a situation where we are using third party purchase and we would like to have ASN generated with outbound delivery and PGI. Vendor sends the material to customer and sends ASN and inbound delivery gets created with serial number updated. Client also wants to have a PGI done which will basically change the serial number status to ECUS from ESTO. We have created SO with PO and IBD . PO has AAC "X" and item category "S" as in the case of third party purchase. Problem we are facing when we do PGR using IBD serial number status remains AVLB instead of ESTO.This happens when we use any AAC. IF AAC and Item category is blank then through IBD we have proper status of serial number with ESTO. Question is are there any controls why system is not changing the serial number status to ESTO when we use AAC ?
