3651101 - Application error when hiring user

Application error "Error message: "java.lang.IllegalStateException: java.lang.IllegalStateException: com.successfactors.genericobject.app.exception.MDFSQLException: com.sap.db.jdbc.exceptions.BatchUpdateExceptionSapDB: [301]: unique constraint violated: Table(GENERIC_OBJECT_T), Index(UK_GENERIC_OBJECT_T_EXT_CODE)(input position -1)"." occurs when attempting to rehire a user.

1. Navigate to the Manage Pending Hires (MPH) page and open the draft for the affected user
2. When trying to save the hire a application error is faced

The error is caused by a conflict involving a MDF object being created/updated during hire process, which leads to a unique constraint violation in the database.

You will need to remove the affected MDF object from the hiring page. To help troubleshooting, you can use a rule trace (2257064) to check if there are any rules setting MDF objects data, like payment information or a custom MDF object, to narrow down the possibilities. 

If you are not able to delete the section MDF during the hire process(like there is no trash icon in the page), you will need to delete the MDF object from the hire template, under Manage Data. This way, the section will not show in the hire process and will not cause the error.
