Reproducing the Issue

Go to edit employee history, search for a user and try to update the user information and you receive the error below :

In the Data Model, the field 'vfld12' is being used for field that is not allowed. This field is reserved for Assigner ID, but Assigner ID is not configured in the Data Model, then the system throws such error message.

You can refer to the Confluence topic for further information: or even to the document 'VFLD1-15' attached in the KBA.


In the Data Model, the field using 'vfld12' must be changed to another ID (vfld1-15) that is not reserved and being used for any other field.
