I am trying to get the Packing Slip Report to run in a new release of R12. I have set up my Packing Slip category and have assigned a sequence to it.
When I release my sales order [ have both reports set up to run in my document set ], my Picking Slip report gets run successfully, but the Packing Slip Report fails due to the following error:
Message Error: The document category has no valid sequence assigned.
My order lines actually get closed [ from an awaiting shipping state ]. As I do not see the Packing Slip report being run in my concurrent request, I ran the Shipping Exception Report, which told me what the error was. My delivery lines get created successfully in WSH_NEW_DELIVERIES, but there are no associated entries in WSH_DOCUMENT_INSTANCES.
Normally Packing Slip Report fires during Ship Confirm.
Follow the notes to generate packing slip report during ship confirm
Can packing slip generation at ship confirm be disabled? What setup steps are required for the packing slip to print successfully? [ID 833988.1]
It worked for me.
Also check the profile option %Sequential Numbering%
In my case it is set as "Partially Used" at responsibility level.
