The below error usually occurs when we run the payroll for a payee using group list who is already being processed by another user through another Group List.
Payee %1 is being processed in Group List %2 run by User %3. There could be other overlaps.
To resolve it, the user needs to be deleted from the other group list used by the other user. Just run below SQL and re-run the payroll for payee in error.
DELETE FROM PS_GP_GRP_LIST_RUN WHERE oprid = '';
