Hi Diana,
if you have your dropdown configured like this:
it should be a simple script like this:
var transaction = session.findById("wnd[0]/usr/cmbPersonas_1453131673643").key; //this is the reference to your dropdown
switch (transaction) {
case "1":
session.callTransaction("MM01"); break;
case "2":
session.callTransaction("MM02"); break;
case "3":
session.callTransaction("MM03"); break;
default:
session.utils.log("No transaction chosen");
}
Didn't evaluate it by now due to system maintenance but it should work like this.
@Edit: Did a short check, works fine for me. Just enter your transaction codes and the reference to your dropdown box.
Regards,
Christoph
