ResultAnalysisInternalID not getting updated in POST API_ENTERPRISE_PROJECT_SRV_0002

[SAPSupport]

When using POST request /A_EnterpriseProject of API API_ENTERPRISE_PROJECT_SRV_0002 to post Enterprise Project data in to SAP S/4HANA Cloud, the project is created but the field "ResultAnalysisInternalID" does not get updated.

Can you explain why?

Hello,

It is the correct behaviour and the API behaves the same as the UI. After the project is created, the Billing Element flag becomes available. Once this is available it is possible to update the Results Analysis key. Therefore, once the project is created, you can use PATCH to update the Results Analysis key, for example,

PATCH /sap/opu/odata/sap/API_ENTERPRISE_PROJECT_SRV;v=2/A_EnterpriseProject(guid'<guidUUID>')

{
    "ResultAnalysisInternalID": "EPMFC"
}
