I need to modify the default value for some screen field for MIRO. This field appers empty, with banks value ; but i need the field appears with some value that i would get from some table.
The request is the new predefined value apperas in MIRO field since the screen appears, that is not only when we save the data but put the value since the user go to transacction and capture the data.
The field i need to put a default value is Business Area (INVFO-GSBER) in 'Details' Tab.
Does some body knows some BADI or User Exit wich i can use for do this action ?
