You are observing the error messages in your SFAPI CompoundEmployee response:
- [EXCEPTION] Exception=[SFAPI Domain Error!] Error Code=[INVALID_SFQL]
- Error Message=[Invalid SFQL! Error: QueryMode DELTA not possible for as XXXXXXXXX MDF version history was not active before yyyy-mm-dd ]
- SAP SuccessFactors HXM Suite
Reproducing the Issue
Run the SFAPI CompoundEmployee and check the response received by the API under Admin center > SFAPI Audit logs or your middlewares.
The error message QueryMode DELTA not possible for SOME_entity_portlet as MDF version history was not active before yyyy-mm-ddT00:00:00Z
This happened because you are using using an last_modified_on in the WHERE segments of the CompoundEmployee > to_datetime('yyyy-xx-xxThh:mm:ssZ'), that is before the "yyyy-xx-xxThh:mm:ssZ" (Date of the object in the EC configuration).
Also in futute we will forbid to use last modified date more than 3 months in the past.
