A packaging supplier group is being onboarded to shared-services invoice processing in SAP S/4HANA Cloud Private Edition. Purchase orders, goods receipts, and standard invoice entries are posting correctly for most suppliers. However, for one service-material supplier segment, invoices can be entered and referenced correctly, but the system keeps the documents in a blocked settlement-review state instead of moving them forward automatically. The same document pattern for stock materials works correctly in the same company code, and the same service-material supplier segment worked in the earlier template company code before harmonization.
The finance process owner wants a controlled correction before shared-services expansion. Manual postings outside the standard process are not allowed, and the fix must remain transportable and aligned with standard governance.
