A PRC ("Product Code") is a 3-character grouping code that every part number belongs to. It drives default vendor, default G/L accounts, lead time, and default shipping/inspection instructions for the parts under it. It helps you define your parts, segment your inventory, and drive reporting by category type.

1. Go to Parts > Lists > PRC List. Access requires the Admin, Engineer, or Manager role.
2. The PRC List report shows each PRC with Num Parts (clickable through to a filtered Part List) and Value of that inventory, plus Default Vendor, Product Manager, and the full set of G/L account columns. There's also an inventory value chart above the grid that can be collapsed.
3. Click Create PRC.
4. Type your new 3-character PRC code and click Create. The code must be exactly 3 characters, ASCII only, and cannot start with a space — the Create button stays disabled until the length is right.
5. The PRC edit modal opens. Here you can set: Default Vendor, Product Manager, Description, Leadtime, Revenue G/L Account, Inventory G/L Account, COS Labor / Overhead / Outsource / Material G/L Accounts, Block Autopick?, Default Cost Center, Default as Non-Inventory, Force Resale, Default AR G/L Account, Default Voucher G/L Account, Default PRC, Incoming Inspection Instructions, and Shipping/Packing Instructions. The last two can be overwritten at the part level.
6. Click Update when done. Delete is on the same row if you need to remove the PRC.
7. To edit an existing PRC later, click the PRC code itself in the list to reopen the same modal. Editing requires the "can edit PRC" permission — users without it see the PRC as plain text instead of a link.
8. To see the new PRC in action, go to Parts > Lists > Part List and click Create New — the new PRC is now selectable in the PRC field.
