Hi Babu,
I carried out the scenario in system and observed that apart from configuration, one checkbox needs to be ticked in Integrated Rule Maintenance. (Activate Reassignment of Order Confirmations).
Looks like it is mandatory. Is it ? To me not all business scenarios need RBA.
As you rightly said the re-assigment (In my case is it stock) to high-prio order took place at the time of order creation. However de-confirmation of lower prio order didnt take place after saving high-prio order.
Any clues if I am missing some step ?
Thanks,
YR
