User exit....Need Help
We have two legacy(same) production Systems for two different corporate locations.
We are implementing SAP(FI only) and planning for a single database for the two legacy Systems into one.
But our customers wants to go to a particular Corporate legacy system so we have decided to create a ZZfield for the customer master table KNA1.
We appended this field in the table KNA1.
We have to pop-up a screen where customer can select by the Corporate office and company code.
Is there any screen exit or BADI to work on?
Is there any alternative way we can work up by using screen numbers?
If possible send me some coding too.
I appreciate your help.
