How to test the integration without a external PLM system

In order to invoke the PLMSI services without a connected external PLM system you can use transaction /iwfnd/gw_client to invoke the REST services.
Please be aware that you may create a mismatch between the external PLM system and SAP if you store e.g. the processing status back to the external PLM system and built some logic on that. (e.g. setting a release status based on processing result).

Steps within transaction /iwfnd/gw_client:

1. Maintain HTTP “POST” for *MaintainRequest / in case of *ReadRequest maintain “POST"
2. Maintain Request URI as mentioned above for the required MDM entity (e.g. for PV: /sap/bc/rest/plmf/plmsi/0002/ProductVersionMaintainRequest)
3. Enter the content-type with “application/json”
4. Maintain the MDM payload into the left lower section. ( Hint: you can send the same payload multiple times. You need to make sure that the messageId is unique. So the easiest way is to count up)
5. Press "Execute"
6. In the pop-up just confirm
7. Result is displayed in the right section
