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. 323 Figure 21.33: Entering data for a new repair Start by identifying the product that will be repaired using the product lot number. Open ERP then automatically completes fields from the selected lot – the partner fields, address, delivery location, and stock move. If a warranty period has been defined in the product description, in months, Open ERP then completes the field Guarantee limit with the correct warranty date. You must then specify the components that you will be adding, replacing or removing in the operations part. On each line you must specify the following: Add or remove a component of the finished product: • Product Component, • Quantity, • Unit of Measure • Price of Component, • Possible lot number, • Location where the component was found, • To invoice or not. Once the component has been selected, Open ERP automatically completes most of the fields: • Quantity : 1, • Unit of Measure : unit for managing stock defined in the product form, • Component Price : calculated from the customer list price, • Source location : given by the stock management, • To invoice or not : depends on the actual date and the guarantee period. This information is automatically proposed by the system but you can modify it all yourself. You can also encode additional charges in the second tab of the repair - applicable list price, address and type of invoice, as well as additional line items that need to be added to the repair bill.
