IDOC_INPUT_ORDERS - First time failure

Hi Experts.

We are using Automaic Sales Order Creation process with respective to PO.

Created the requied partner profiles WE20, VOE4, VOE2, and VD51 settings.

ISSUE:

When ever we create Purchase order with new Material and Vendor combination FOR THE FIRST TIME, the Inbound IDOC (which creates Sales Order) is failing and when you re-process it is creating Sales Order. After then the IDOC is not failing at-all.

What we tried:

- E1DP19 QUALIF we are passing 001 - (Customer Material). Also tried with 002 and with out Customer Info record also we are facing the same issue.

- Similar issue is there for item categories with BOM, but we are not using those item categories.

Expecting your inputs.

Regards,

Mohan Vamsi
