Standard API ODATA v2 Class Data for Classification

[jmhvieira]

Hello experts,

has anyone in this community ever implemented this API?  I kindly ask for your assistance. I'm facing an error when posting a request to create a class header, however I'm able to perform a get entity set to read the existing class headers.

API: https://api.sap.com/api/OP_API_CLFN_CLASS_SRV/overview

I'm currently using a S4HANA on premise 2022 FPS01. I already tried the same API in a more recent system but unfortunately, I got the same error message.

URL Request:

(...)sap/opu/odata/SAP/API_CLFN_CLASS_SRV/A_ClfnClassForKeyDate   

HTTP Method:

Post

JSON:

{
   "ClassType": "300",
   "Class": "API_test1",

       }
   ],
   "to_ClassKeyword": [
       {}
   ],
   "to_ClassText": [
       {}
   ]
}

Status:

Thank you,

Try removing the "to_class": {} association that it is complaining about in, and probably best to remove the other associations with no data.

   "to_ClassDescription": [
       {
            "Language": "EN",
           "ClassDescription": "API_test1",
           "to_Class": {}          
       }
   ],
