AI Wrote a Prophet 21 Purchase Order. The One Field It Must Never Send.

Why "Column is disabled: supplier_id" kills your P21 PO import, and the field to send instead. One Telegram message to Ginger, my MeshHand assistant, on my Prophet 21 test company: "make a PO for 10 MESH-DEMO-18 from Big Bell." She raises a real purchase order through the P21 Transaction API, ONE call to the Purchase Order Entry window with a header and one line, and P21 numbers the PO. Then we check her work in Purchase Order Entry. Plus the three lessons we learned the hard way: send vendor_id and let P21 fill the supplier (send supplier_id and P21 says "Column is disabled"), the buyer is required on this install, and a new item's first PO line comes in at a price of zero unless you send the supplier cost. This is the full power that you can give to Ginger, but initially we start her off with read-only access. Every skill she has is one we gave her on purpose.
