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

https://help.sap.com/docs/SAP_S4HANA_ON-PREMISE/04f8d809ad314e3ea009ad2dc88b3d7f/f1b0af0d9f0641dead5c120466845d3f.html

My guess is faulty data with Attribute SchedldBasicEarliestStartDate is empty which should be not empty because it is a key field?

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.

Hi,

I tried in our practice system and I didn't encounter the same error as you did.

Can you check the data (SchedldBasicEarliestStartDate) of the first two entries from SE16? Probably it's due to some erroneous data. Also, can you exclude the date field from the response by specifying a select query option? And see if you still get the error?
