2974296 - Deficit of PU GR quantity in API (M7021)

Symptom

When creating a Return delivery to vendor (movement type 122) via the Odata API_MATERIAL_DOCUMENT_SRV you are running into error message M7021 and the posting fails.

Environment

SAP S/4HANA Cloud All versions from CE2011

Reproducing the Issue

Post a 122 movement via API_MATERIAL_DOCUMENT_SRV

Cause

GR based IV case, missing the required reference fields in the payload. 
If you have a regular Purchase Order Item with a stock material, you can post a 122 return via the API with reference to the Purchase Order. 
If you have a regular Purchase Order Item with a stock material and with the 'GR Based IV flag' set, you can post a 122 return via the API but you must pass the assignment block reference as well as the Purchase Order.

Resolution

In the payload, pass the corresponding assignment block fields: 
...
"InvtryMgmtReferenceDocument" : "xxxxxxxxxxx",   (mseg-lfbnr) 
"ReferenceDocumentFiscalYear" : "xxxx",                  (mseg-lfbja) 
"InvtryMgmtRefDocumentItem" : "xxxx",                  (mseg-lfpos) 
...

Note: In Cloud release CE2008 the API does not fully support the GR Based IV processing, these reference fields are not available until CE2011
