Custom Fields and Logic -- APS_CUSTOM_FIELD_MAINTENANCE_SRV -- 500 Internal Server Error

[SG]

Hi,  I tried to add some custom fields to an existing ui5 application using Custom Fields and Logic Application (CF&L) . When I add the field i am getting a time out error .please help me resolve the issue.

1.  I opened the (CF&L) app and  added a code list to EHFND_TASK_DEFINITION .

2. When i click on create in the backend there is a OData call made to the service sap/opu/odata/sap/APS_CUSTOM_FIELD_MAINTENANCE_SRV/$batch? and an 500 error is recieved

3. I checked the Service in the Gateway Client and it is loading the metadata well . I also Ran the Same Post Query with the same payload that was sent from the Browser. 

I am getting the message as 

<code>CX_APS_CUSTOM_FIELD_TECH</code>

<message>Operation failed. Report an incident on component BC-SRV-APS-EXT-FLD.</message>

Thanks for all the help and your time.

Hello ,

Please do a get request to see if the custom field is actually added to API.

If not once a custom field is created it have to added to the relevant context. so select the custom field and click on the section API and enable the field usage for the same.

And Example screen shot is attached here from a Sales billing is attached here.

Also do publish the field once the changes are completed.
