Issue with reversal of a GR for Sub-Contract PO from Decentralized EWM System to ECC 6 EHP 8

[sumukhip]

We have decentralized EWM System and ECC for our ERP. Goods Receipts are recorded in EWM and transmitted to ECC where in a material document is posted and updated in PO History. For a Sub-Con PO when GR is posted, inventory for components is consumed. In this case a GR posted previously was incorrect and needed to be reversed for 1 batch i.e. 1 material document reversal out of 18 Mat Docs that were posted. There were no issues with reversal in EWM but the reversal failed to post in ECC. We do use Inbound Deliveries. We have failed Queue in SMQ2 with error 'enter item'. 

Based on our analysis it’s calling standard VL09 transaction and expecting to have inbound delivery line item for all the components while cancelling the material document in ECC. This seems to be standard SAP behavior. Anyone has experienced such an error with similar set up of EWM-ECC. If you please share details on how you resolved the issue.

Hi @sumukhip ,
The issue you are encountering is a known issue in decentralized EWM–ECC integration. When reversing a Goods Receipt for a Subcontracting PO, ECC expects inbound delivery line items for all consumed components. If those items are missing or mismatched, the reversal fails with the “enter item” error in SMQ2. The resolution typically involves ensuring inbound delivery item consistency, adjusting customizing for GR reversal, or applying SAP notes/patches that enhance VL09 handling for EWM-driven reversals.

You can try few options to resolve this as mentioned below.

1. Inbound Delivery Item Check: Ensure inbound delivery has all component items linked to the PO. If items are missing, manually adjust the inbound delivery before retrying reversal.

2. GR Reversal Settings in EWM: SAP introduced enhancements like “Reverse after Putaway” and Enhanced GRR functionality in newer releases (S/4HANA 2021 FPS01 onward). These allow partial reversals and better handling of inbound deliveries. In older ECC/EWM setups, reversal is often “all-or-nothing” at the Goods Movement document level.

3. SAP Notes / OSS Messages: Several customers reported similar failures in SAP Community. The workaround was either applying corrective SAP notes or upgrading to a release where GRR supports single inbound delivery reversals.

Example: SAP note fixes ensure VL09 doesn’t require all components if reversal is for a single batch.

4. Manual Workaround: Reverse the GR in ECC directly using VL09 with the inbound delivery reference, ensuring all items are selected. Then reprocess the failed queue in SMQ2.

Hope above options will resolve your issue

Thank you for your response! Yes GR Reversal even after PTWY is made available by SAP in S4H2025 Decentralized for Ext. Procurement, via new option in EWM Decentralized Config "Set Control Parameters for ERP Version Control for GR Reversal after Putaway" but not in the version we are on. version.
