Routing Impact on the production order

21.12 Manual procurement

To procure internally, you can create a procurement order manually. Use the menu Warehouse → Schedulers → Procurement Exceptions and click on New button to do this. Figure 21.29: Encoding for a new procurement order The procurement order will then be responsible for calculating a proposal for automatic procurement for the product concerned. This procurement wll start a task, a purchase order form the supplier or a production depending on the product configuration. Figure 21.30: Workflow for handling a procurement, a function of the product configuration It is better to encode a procurement order rather than direct purchasing or production, That method has the following advantages: The form is simpler because Open ERP calculates the different values from other values and defined rules: purchase date calculated from order date, default supplier, raw materials needs, selection of the most suitable bill of materials, etc The calculation of requirements prioritises the procurements. If you encode a purchase directly you short-circuit 321 the planning of different procurements. Tip: Shortcuts On the product form you have an ACTIONS shortcut button Create Procurements that lets you quickly create a new procurement order.

21.13 Management of waste products and secondary products

For the management of waste you must install the module mrp_subproduct. The normal behaviour of manufacture in Open ERP enables you to manufacture several units of the same finished product from raw materials A + B C. With waste management, the result of a manufacture can be to have both finished products and secondary products A + B C + D. Note: Waste material In Open ERP waste material corresponds to secondary products that are a by-product of the main manufacturing process. For example, cutting planks of timber will produce other planks but these bits of timber are too small or the offcuts may have value for the company if they can be used elsewhere. If the module mrp_subproduct has been installed you get a new field in the Bill of Material that lets you set secondary products resulting from the manufacture of the finished product. Figure 21.31: Definition of waste products in a bill of materials When Open ERP generates a production order based on a bill of materials that uses secondary product you pick up the list of all products in the the third tab of the production order ‘Finished Products’. 322 Figure 21.32: A production order producing several finished products Secondary products enable you to generate several types of products from the same raw materials and manufacturing methods – only these are not used in the calculation of requirements. Then if you need the secondary products Open ERP will not ask you to manufacture another product to use the waste products and secondary products of this manufacture. In this case you should enter another production order for the secondary product. Note: Services in Manufacturing Unlike most software for production management, Open ERP manages services as well as stockable products. So it is possible to put products of type Service in a bill of materials. These do not appear in the production order but their requirements will be taken into account. If they are defined as Make to Order Open ERP will generate a task for the manufacture or a subcontract order for the operations. The behaviour will depend on the supply method configured on the product form Buy or Produce.

21.14 Management of repairs

The management of repairs is carried out using the module mrp_repair. Once it is installed this module adds new Manufacturing → Manufacturing → Repair Orders menu under the Manufacturing menu for creating repair jobs and reviewing repairs in progress. In Open ERP a repair will have the following effects: • Use of materials: items for replacement, • Production of products: items replaced from reserved stock, • Quality control: tracking the reasons for repair, • Accounting entries: following stock moves, • Receipt and delivery of product from and to the end user, • Adding operations that can be seen in the product’s traceability, • Invoicing items used andor free for repairs.

21.14.1 Entering data for a new repair

Use the menu Manufacturing → Manufacturing → Repair Orders to enter a new repair into the system. You will see a blank form for the repair data, as shown in the figure Entering data for a new repair below.
