SAP S/4HANA Cloud Public Edition

1. Identify an outbound delivery for which Post Goods Issue (PGI) has already been successfully posted.
2. Retrieve the delivery number and the corresponding ETag (If-Match value).
3. Obtain a valid X-CSRF token.
4. Call the OData action PostGoodsIssue of API_OUTBOUND_DELIVERY_SRV with the X-CSRF token and If-Match value obtained from previous steps.
5. See error "State of the resource (entity) was already changed (If-Match)" raised in response.

Incorrect API version parameter in the OData service URL:
Using an uppercase “V” (for example, “V=0002”) leads the call to resolve to an obsolete service version (“service_version” reported as “0001”), resulting in the 412 Precondition Failed response.

Use the lowercase version parameter in the OData service URL to target the intended service version, for example:

POST <host>/sap/opu/odata/sap/API_OUTBOUND_DELIVERY_SRV;v=0002/PostGoodsIssue?DeliveryDocument='80000000'.
