I want to change the warning message into error message in the standard VA01 transaction..
The steps I follow :
order type -->
enter
sold to part -->
ship to party -->
Purch order no -->
Req deliv date -->
Material -->
Order quantity -->
SU -->
enter.
The warning error dispayed is
No add. vendor / customer data maint. for 16320340 - please maintain J_1IMOCUST...
Want to change the above into error so that it shud not go further.
