Symptom
Creating a Supplier Return Delivery on blocked stock reduces the available stock for other Outbound Customer Deliveries, even though no availability check is active on the return item category.
Environment
SAP S/4HANA Cloud Public Edition
Reproducing the Issue
- Have 25 pcs in blocked stock and 40 pcs in unrestricted stock.
- Create a Customer Delivery LF for 30 pcs.
- Create a Supplier Return Delivery RL for 25 pcs on blocked stock.
- Result: Only 15 pcs remain available for LF (instead of 40).
Cause
Schedule Line Category RN transfers requirements to MRP/ATP by design, regardless of the special stock used for the return. This is standard behavior.
Resolution
Use a dedicated Storage Location for Supplier Return stock, excluded from ATP for Outbound Deliveries:
- Create a dedicated Storage Location for returns
- Exclude it from availability check
- Transfer Blocked Stock to be returned into this location
- Create the RL Delivery from this location
Customer Deliveries LF are no longer impacted.
