I am a programmer, I'm trying to figure out the business logic on the two screens mentioned above. They both process PO's but as I am a developer and not an end user or power user, I am trying to figure out the differences to why you would use one or the other, do they do the same functionality? Or are they used together in a bigger process I am not seeing? Anyone with information to why I would use one or the other or any supplemental information would be appreciated. I'm trying to understand how these two screens work with similarities and/or differences between them.
thank you kindly.
