I need the standard solution for the following scenario .
Business has 15 sales processes ex. Order types from a1 to a15, delivery type Eg. a1 to a15 and billing type Eg a1 to a15. The requirement is system only should allow a1 order type with a1 delivery if it is a2 delivery system should prompt an error. As a process to solve this I have assigned delivery type @ vov8 as a1 but if I change in the vl01n as Lf system taking which should not happen in my requirement.
Thanks in advance.
