From all the articles I have read and my own knowledge of ABAP Programming, I understand that it is used for reports and dialog modules. To do transactions a stuff. My project involves an application to do configuration decisions at pre-implementation stage and I'd hope that it can directly impact SAP's IMG interface. Say for example, I made a business decision to "switch-off" ERS within Invoice Verification, can I program a script to be triggered to do that in IMG automatically? If so is it using ABAP or something else?
