Thank you for you respond. The mistake i made is i dint click start function call server button in the beginning.
Once i clicked It and Update PO. Everything turns out well.
What is the Reference Type No. set to on your Workflow Template?
Said another way, this is the table that the workflow and its to-dos will pay attention to. I suspect that you have the workflow attached to Purchase Header, but you are trying to trigger an event from Purchase Line, which is where quantities are stored.
