Hi;
I want to write a validation rule about Cost center and accounts. scenerio is; for dont post 730XXXXXXX account for cost center 1000..
go to GGB0
prerequisite => cost center ='1000'
control => NOT account LİKE '730*'
and GGB4 I active the this rule.
and cost center and account is the message variables. when I execute it, it doesnt work as my expectation. where did I make mistake?
