How to manage the SAP stock locations for non-conform materials?

Quality dept. has the "ownership" of non-conform stock locations listed below.

Ownership is per plant (xx = 20 for Bulgaria, xx = 11/12/13/14 for Belgium, xx = 43 for Germany).

xx60: Non-conform materials returned to Vendor

Note1: Materials need to be booked to xx61 (preferably with the SQM-ticket as reference, or with information who instructed the booking for traceability) once the non-conformity is "confirmed" (e.g. after review of the ticket created by Inbound Material Inspection by Supplier Quality).  As long as the non-conformity is not "confirmed" best practice is to keep the materials in QM-lot.

Note2: When materials are sent to the supplier (e.g. for analysis, rework,..) they need to be booked (from xx61) to xx60 (with the SQM-ticket as reference).

Note3: Both xx61 as xx60 are "not MRP relevant" which means that materials booked to xx61 or xx60 will trigger SAP to find a solution for the "need" for them.  When there's insufficient stock, this will result that SAP to launch a Purchase Order Request, and Purchase to re-order the materials.  Therefore, Purchase/Planning must be involved in the process to communicate NCR's (see here) in order to create a "reservation" in SAP.

Note4: It is acceptable if materials stay in xx60 or xx61 "without reservation" to follow-up receival of a credit note.  In that case, the field "Status of Correction" of the ticket (which can be found in the booking reference) should be set to "... - Credit requested".

Note5: Quality dept. of every plant is responsible to regularly (min. quarterly) review all materials in xx60/xx61 to follow-up progress towards a "solution".
