3236899 - Error "General Error with error code - -28" while doing an Upsert on User OData API


You are doing an Upsert in User API and the error below occurs:

"[COE0019]Failed to add/update user [123456] \"\" (N/A;N/A;N/A): General Error with error code - -28.\r\n with the index 0"


  • SAP SuccessFactors HXM Suite
    • OData API


Error code "-28" means "EXTERNAL_NOT_SUPPORTED: External User import is currently not supported. The following users were not imported".

This means that the user receiving the data from the Upsert has status equal to "e", meaning that it's an active external user.


The User OData API only works for internal users, meaning that an Upsert on an active external user won't work.
