PPOME BADI/ User exit for position delimit function

Hi Experts,

My client is using PPOME transaction to delimit the position (select position -> right click -> Delimit -> Object). But they want to have a validation rule to check if the position has any future date assignments, then system should throw the error message.

I found the BADI HRBAS00INFTY, but this BADI is not been called when I click on "Object" function. Is there any other way which I can achieve this.

Thanks in Advance.

Regards,

Suresh
