Some times after completing the Development work, developer forgets to enter the IT operator & tester BP, so the workflow will not trigger to these two users. So i made these 2 fields as mandatory fields. Now If i want to set the Action as in dev, i need to enter these 2 BP's or else system will not allow me to change the status into in dev. But my requirement is to enter these 2 BP's after the completion of Dev work & releasing of the task. I want error when i try to save the doc after completion dev work. Can any body help me to achive this ?
