1. Serial number tracking of parts: While adding parts to a work order, you can select the serial number for the parts, enabling you to identify the exact part used for a work order. Serial number tracking for an item can be only enabled from Zoho Inventory. Also, serial number tracking can be used only if Zoho FSM is integrated with Zoho Books.
2. Choosing warehouse for a part: While adding parts to a work order, you can choose the warehouse (defined in Inventory) from which to fetch the part. As parts get used in Zoho FSM, the stock in the warehouse for these parts will also get updated in inventory. The change in quantity of a part in Zoho FSM can be used in Inventory to maintain the Reorder Point.
