Date type 04 already exists error during Rehire action

Hi Friends,

The requirement is that, during the Rehire action the Date Type 04 i.e. Hire Date needs to be updated with the Rehire date automatically. Below is the code done in T588Z to achieve this. In this code 03 stands for Rehire action.

The date is updated correctly if the Date Type 04 already exists in the filed DAR04, but if the Date Type 04 exists in some other field like DAR03 then the system gives an error "Date type 04 already exists". Please see below snapshot.

Is there a possibility to fix the above issue with some changes in T588Z or some other approach needs to be done?

Please share your thoughts.

Thank you in advance.

Regards,

Vish
