Security days Calculation of lead times

317 put the operation on hold and start again later. The following process is attached to each operation. Figure 21.26: Process for handling an operation Thanks to this use by operation, the real working time is recorded on the production order. The production order is automatically put into the state ‘In Production’ once the first operation has been started. That consumes some raw materials. Similarly the production order is closed automatically once the last operation is completed. The finished products are then made.

21.10 Events and barcodes

If the company wants to work with barcodes in manufacturing you can work on each operation using events. Here are some examples of events for an operations: • Starting an operation, • Pausing an operation, • Restarting an operation, • Closing an operation, • Cancelling an operation. You can print barcodes for the workcenters using the menu Manufacturing → Configuration → Resources → Work Centers . Click on the report action Work Centers Barcode to generate the barcodes for that work center. 318 Figure 21.27: Capturing events for work orders Open ERP then applies the events to the relevant operation.

21.10.1 Subcontracting manufacture

In Open ERP it is possible to subcontract production operations for example painting and item assembly at a supplier’s. To do this you must indicate on the relevant routing document a supplier location for stock management. You must then configure a location dedicated to this supplier with the following data: • Location Type : Supplier, • Location Address : Select an address of the subcontractor partner, • Chained Location Type : Fixed, • Chained Location If Fixed : your Stock, • Chaining Lead Time : number of days before receipt of the finished product. Then once the manufacture has been planned for the product in question, Open ERP will generate the following steps: Delivery of raw materials to the stores for the supplier, Production order for the products at the suppliers and receipt of the finished products in the stores. Once the production order has been confirmed, Open ERP automatically generates a delivery order to send to the raw materials supplier. The storesperson can access this delivery order using the menu Warehouse → Warehouse Management → Internal Moves. The raw materials will then be placed in stock at the supplier’s stores. Once the delivery of raw materials has been confirmed, Open ERP activates the production order. The supplier uses the raw materials sent to produce the finished goods which will automatically be put in your own stores. The confirmation of this manufacture is made when you receive the products from your supplier. It is then that you indicate the quantities consumed by your supplier. Tip: Subcontract without routing If you do not use routing you can always subcontract work orders by creating an empty routing in the subcontract bill of materials. Production orders are found in the menu Manufacturing → Manufacturing → Manufacturing Orders. A production order is always carried out in two stages: 1. Consumption of raw materials. 2. Production of finished products.
