Material-routing relationship

A work center consists of a number of machines, executing more than one production order at the same time. Depending on the configuration multiple machines can be dedicated to a specific task, or multiple tasks performed on one machine.

To accommodate these requirements flexibility is needed in the use of the available machinery through deviation from standard routings, and the defining of situation dependant operations.

If the Quantity-dependent Routing check box in the Item - Production (tiipd0101m000) session is selected, LN uses one of the quantity dependent routings you defined for the item in the Item - Routings (tirou1101m000) session once the specified quantity is reached. 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 Quantity-dependent Routing check box in the Item - Production (tiipd0101m000) session, LN takes into account the routing that you defined in the Default Routing field in the Job Shop Master Data 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 bill of material (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.

Enterprise Planning takes routing specific material/operation links into account when:

  • 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 the Material-Routing Relations check box in the Bill of Material (tibom1110m000) session is selected, 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.

Example

For manufactured item MAN001 the default routing STD and alternative routing ALT exist. Operations 10 and 20 are defined and linked to both routings.

The bill of material for MAN001 consists of line 10 for MAT001, line 20 for item MAT002 and line 30 for item MAT003.

In the BOM Line - Material-Routing Relationships (tibom0140m000) session, the following relations are defined:

  • Line 10 for routing STD is linked to operation 10
  • Line 10 for routing ALT is linked to operation 10
  • Line 20 for routing STD is linked to operation 20
  • Line 20 for routing ALT is linked to operation 10
  • Line 30 for routing STD is linked to operation 20
  • Line 30 for routing ALT has no operations linked

Two production orders are generated:

  • SFC000001 with routing STD
  • SFC000002 with routing ALT

All three material components defined in the BOM appear on both production orders.

The estimated material lines are:

  • SFC000001 (STD)

    • Line 10 linked to operation 10
    • Line 20 linked to operation 20
    • Line 30 linked to operation 20

    SFC000002 (ALT)

    • Line 10 linked to operation 10
    • Line 20 linked to operation 10
    • Line 30 linked to operation 10

Note: MAT003 (line 30) is not linked to any operation of the ALT routing, the item cannot be found in the estimated material lines of the production order using the ALT routing.
