Personal Services - W4/Bank Custom Messages and Badi's
We are in the process of implementing ESS and have a few custom rules for certain infotypes built in to the old PA users exits. For example, we do not allow associates to have more than 3 banks, we will not allow associates to change W4 information if they have a tax levy, etc.
Does anyone know of a way to send a message to the screen if an ESS user tries to make changes such as trying to enter more than three banks? There is a nice Badi in the Leave Request service that allows for checks and messages to be displayed on the screen but unfortunately I am not seeing anything (a Badi to send messages) for the Personal Services W4, Bank, Address, etc. Has anyone encountered this and if so, what did you do?
Thanks for your help.
