As per the documentation, the WBS element ID is required.

https://help.sap.com/docs/SAP_S4HANA_ON-PREMISE/04f8d809ad314e3ea009ad2dc88b3d7f/f1b0af0d9f0641dead5...

hi Rammel,

I tried the below URL and I got the successful response
/sap/opu/odata4/sap/api_project_v3/srvd_a2x/sap/project/0001/WBSElement?$top=2&$skip=2

the value for  "SchedldBasicEarliestStartDate" : null,

But for the GET /sap/opu/odata4/sap/api_project_v3/srvd_a2x/sap/project/0001/WBSElement?$top=2   

I am getting the below error in the Error log. I am facing the issue with ?$top=2 only.
Error occurred while processing property 'SchedldBasicEarliestStartDate' of entity with index 1
Property 'SchedldBasicEarliestStartDate' has invalid value ''

Parameter has invalid value: Parameter IV_VALUE has invalid value .

For Project entity also ProjectInternalID is Mandatory. But without passing ProjectInternalID also, I am getting the response.
/sap/opu/odata4/sap/api_project_v3/srvd_a2x/sap/project/0001/Project?$top=2

You are right, even without the WBS element, it works.
