Hi guys,
Today we have tried to creat a substitution for the network activity (Tcode: OPSN). we also create some by reference the existing ones. When we choose form menu Edit->Validation/Substitution->Substitution, it really triger the our defined exit. But when we save the network, after we change the activity. It trigger nothing! So I am very confused.
Welcome any suggestion!
thanks very much!
