User exit in planned Orders

Hello all.

I have been search for a user exit in planned orders that allow me to define some code in it to triger some changes. this user exit should be at time of planned order is saved.

I have already search in this forum and I found out how to find the user exits by transaction. I have tried for transaction MD12 but did not found any suitable user exit.

Does any one know any user exit that could make my life easiser 😊

thanks

Manuel Antonio
