| Purpose of linking materials to operations Linking an operation to a material allows for: Phased issue of materials. Use of shop floor warehouses. Application of operation scrap and yield. Phased issue of materials Linking operations to materials reduces stockpiling of raw materials and intermediates, as it allows to determine accurate delivery dates. For instance, the Resource Requirement Planning module in Enterprise Planning uses the operation by material to determine the delivery time concerning planned purchase and production. If a material is not linked to an operation, ERP LN will assume that the material is needed at the start of the first operation. If a production order has no operations, ERP LN will assume that the material is needed at the start of the production. Use of shop floor warehouses By linking an operation to a material, ERP LN determines from which shop floor warehouse the material is to be issued. A work center is linked to an operation, and a shop floor warehouse is linked to a work center. Application of operation scrap and yield The calculation of the estimated quantity of a material is affected by the scrap quantity and yield percentage of the operation where it is used. Materials must be linked to the operations where they are used in order to achieve an accurate estimate. How to link materials to operations You can link materials to operations in two ways: In the BOM In the Bill of Material (tibom1110m000) session, enter the operation in the Operation field. In the BOM Line - Material-Routing Relationships (tibom0140m000) session In the BOM Line - Material-Routing Relationships (tibom0140m000) session, specify the routing code and the operation. Note An item can have several routings. In the BOM, you can enter one operation number, which then applies to all routings of an item.
