We have additional options displaying in the transmission methods section after upgrade to 12 C. Earlier the 'None' option was not available and we do not have any form personalisation this window.
Navigate to Purchase Orders >Purchase Order
Enter PO details and submit for approval.
Can you please advise where this is coming from and how can we reset it back to the earlier state so that the 'None' option does not display .
Is there any setup or profile option that need to be changed?
