Hi,
You're taking the long way home. People do this all of the time with Purchase Orders for Adagio.
You can use a Sundry Vendor setup to record the Due to/from between plants for your internal transfers.
This assumes you are not using an Adagio BOM to do the assembly in the other plant. It sounds like you are just building the product and tracking the finished goods transfer.
You create a PO to yourself (Sundry Vendor with GL Account) which in effect shows as a qty on PO for the item(s) you are making. It creates a PO or traveller requisition to generate the activity, say in your other plant, or could be in your own plant.
Use the traveller document (or copy of) in the other plant as a shipping document. When the production is received at the selling plant, receipt it into inventory (in Purchase Orders for Adagio) at your costs defined in your original work order.
This process then shows all of your internal PO's (Work Orders in progress), and effectively receipts them into your finished goods inventory, at the initiating plant. Not sure how you intend to account for production at the other plant, but it could also be down through their OE to the related plant as a customer.
You will need Purchase Orders for Adagio. If anyone else is using Inventory and Order Entry without or has not considered Purchase Orders for Adagio for just plain efficiency, they are also taking the long way home. If you do distribution, you need Purchase Orders for Adagio.
If you need help with this setup, you should contact your Adagio consultant or us. 800-540-3164.
Best,
Brian
