I just got off of chat.  I am a fairly new user and my supplier scolded ME TOO for not having a part number on the PO.  I just had not even looked at the pdf since I can see all of the needed information on my purchase order form.  The desktop version does great - So I mentioned that to the chat and they told me "they are two different products".  So now I'm getting really frustrated and tell them "you mean to tell me I have a purchase order system that WILL NOT show a part number?"  Here is their response:  "I'm really sorry but what your're asking is beyond the scope of what we can do.  Here's what I CAN do:  I would be glad to send this suggestion up to have it considered in future improvements....."  WHAT?  A future improvement?  Why would I NOT want a PN on my Purchase order, TO PURCHASE PARTS?  I'm stunned.  I did the work-around and copied the PN over to the Description (and made the description field longer so it won't wrap) .  Did I mention that I am STUNNED?  Why would you not keep a key feature like Part Number or SKU printing ON A PURCHASE ORDER?
