| # Material-routing relationship Typically a work center consists of a number of machines handling one or more production orders. Usually more than one machine is available to perform a certain task, and several tasks can be performed with one machine. This requires a lot of flexibility from the available machinery, which is why you must be able to deviate from a standard routing, and to define situation dependent operations in a specific routing. If the Quantity-dependent Routing check box in the Items - Production (tiipd0101m000) session is selected, LN selects a routing based on the ordered quantity, by using one of the quantity dependent routings you defined for the item in the Item - Routings (tirou1101m000) session. Which routing LN selects is determined by the value you specified in the Quantity Ordered field in the Production Orders (tisfc0501m000) session. Note If a quantity dependant routing is used, the material-routing relationships are not taken into account. If you do not select the Quantity-dependent Routing check box in the Items - Production (tiipd0101m000) session, LN takes into account the routing that you defined in the Default Routing field in the Routing Parameters (tirou0100m000) session. Enterprise Planning can take into account specific material-routing relationships during the order planning run, and creates planned orders based on the routing operations linked to a specific BOM line of the main item in the BOM Line - Material-Routing Relationships (tibom0140m000) session. The material-operation link in the bill of material (BOM) becomes routing dependent. You can link multiple routings to a main item, and for each separate routing you can link a specific operation to the corresponding components in the BOM lines in the BOM Line - Material-Routing Relationships (tibom0140m000) session. Whether Enterprise Planning takes into account routing specific material/operation links depends on the following: You linked more than one routing to a main item in the Item - Routings (tirou1101m000) session. You set the Operation field of a specific BOM line in the Bill of Material (tibom1110m000) session to zero, which means that the field is empty. If these conditions are met, and you selected the Material-Routing Relations check box in the Bill of Material (tibom1110m000) session, LN creates planned orders based on the routing operation that corresponds with a specific BOM line in the BOM Line - Material-Routing Relationships (tibom0140m000) session. If you did not select the Material-Routing Relations check box in the Bill of Material (tibom1110m000) session, LN plans orders for all the items listed on the corresponding BOM at the start date of the first operation of the routing.
