This program will print the Blanket Releases only.
Based on the screen shot, you haven't mentioned the release number, can you try running it mentioning the release number.
You may not be able to email the PDF bu running the program.
Actually this program gets fired by Oracle upon PO approval which communicates the PO to supplier based on the notification method mentioned in the PO.
I know the PO approval process will automatically communicates the PO Release to supplier based on the notification method mentioned in the PO.
But what happens when the Release is created by the Create Releases process, which automatically creates and approves the Release? This is my issue. When Create Releases runs and generates a new release, we need the process to also communicate the PO Release to supplier. How can this be done?
