Dear expert,
We have enabled the following Odata APIs on our system.
-API_PURCHASEORDER_PROCESS_SRV
-API_MATERIAL_DOCUMENT_SRV
-API_SUPPLIERINVOICE_PROCESS_SRV
These APIs work fine for GET methods (return 200), but return 405 Method Not Allowed errors for POST methods.
I referred to the contents of the following sites
Is there any special procedure required for using OData API in S / 4 HANA?
Best regards.
Daisuke.
