| # Material-routing relationship A work center usually consists of a number of machines and, mostly, more than one production order is executed at the same time in a work center. Usually more than one machine is available to perform a certain task, or several tasks can be performed with one machine. This requires a lot of flexibility in the use of the available machinery, which is why you must be able to deviate from a standard routing to alternative routings, and to define situation dependent operations in a specific routing. If the Order Qty-dependent Routing check box in the Items - Production (tiipd0101m000) session is selected, LN selects a routing based on the ordered quantity, that is, 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. In this situation, LN does not take into account material-routing relationships. If you do not select the Order Qty-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. In other words, 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 conditions: -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 0, 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. |
