Hi John,
Yes the event log points out that all the workflow steps have been competed successfully. when i check in the PO window the Po is created. However my query was - failing to apply further approval levels to this newly created PO, thus i had a problem. Nevertheless,
I spoke to the Paccific Solutions tech support. They have attended to my query, by saying that once a PO is created from the PR, no more further approval levels can apply (logically), which actually makes sence. Which is exactly what i was looking for, as an answer. I think i failed to explain my problem clearly in this thread. However, thank you for your feedback!
