hi all
I have two mandatory variable in my selection like vendor and customer.
my requirement is like that
" Either vendor or customer is mandatory, not both"
means
1> if we execute the query, and put both the value in selection screen and execute system should give above message and come back to that selection.
2> if we put both the field remain blank system should give same message.
3> if we give any one of them it should execute properly.
thanks
samit
