You are in a business scenario where a customer component (serialized material), which is received in valuated sales order stock (special stock E), must be delivered to a third party service provider in subcontracting, with relevant spare parts (special stock O).
The process is originated in the Customer Service module where a “Returns and Repair” scenario supports the material return (inbound delivery) from Sales order type RAS Repairs / Service, on the plant, in a valuated sales order stock. Based on a repair procedure a Service order is created from the Repair order to track repair activities which are mainly executed at the workshop (planning plant). Our customer needs to deliver the component to an external service provider. Service order and Repair order have both a PS WBS account assignment.
Relevant business functions for Maintenance and Service processing in the Aerospace & Defense industry (MRO) are active including LOG_EAM_ROTSUB, A&D Maintenance, Repair and Overhaul AD_MRO_CI_1, Material Exchange with ATP Check AD_MRO_CI_2, Rotables/Sharing of Spare Parts, Subcontracting Improvements AD_MRO_CI_3 with exclusion of LOG_EAM_ROTSUB_2 for which EHP5 would be required.
OSS relevant notes
OSS note 863154 A&D (Subcontracting components from special stock) adds additional issues to the above described business scenario “It is not possible to use different special stock types for the main component and the consumption components”
OSS note 1380479 (Prevent usage of val. spec. stock with subcon with PM ord.) this note describes the scenario but its meaning and result is unclear
Solution
AD_SUBCON094 (valuated sales order or project stock and account assignment to PM/CS order): In A&D subcontracting process only one accounting object is allowed per PO item. If you have valuated sales order stock, account assignment to sales order item is used on account Assignment tab.
If you have account assignment to PM/CS order, special stock maintained on Spec2000/SC tab should be non-valuated, therefore flag “GR non-valuated” (EKPO-WEUNB) is set on Delivery tab.
Although functionality for MAA exists since EhP4, A&D subcontracting processes are not aligned to use multiple account assignments.
Concernin using different special stock on component level. Currently only one special stock type is supported on PO item andcomponent level.
Main component and all consumables should be posted to the same special stock prior to the outbound delivery or transfer posting (in your case from project stock to sales order stock with standard movement 413).
In A&D subcontracting process, main rework material and consumable components move together during different postings (either 541 or 101/543) between stock at storage location and stock at subcontractor, namely individual/collective requirements are not considered (MARC-SBDKZ).
