3721306 - "OkToRehire" field cannnot be updated via import for Termination event for Higher Duties

Error appears while importing the field "Ok to Rehire" to Yes, for temporary assignments. 

SAP SuccessFactors Employee Central

1. Navigate to Import Employee Data.
2. Select Termination Details and choose the file.
3. Observe the error during validation/import: "XXX is an invalid external code for event reason."

Expected behaviour. 

After a higher duty or temporary assignment is terminated, it cannot be reinstated (re-hired). Hence, the system will show an error and will not allow to edit the records. Additionally, Higher Duty does not support the import of Employment Termination Information; therefore, the import will fail.
