Link materials to operations

Linking an operation to a material allows for:

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 Order 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, LN will assume that the material is needed at the start of the first operation.
- If a production order has no operations, LN will assume that the material is needed at the start of the production.
Use of job shop warehouses

By linking an operation to a material, LN determines from which job shop warehouse the material is to be issued. A work center is linked to an operation, and a job shop 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.

Linking materials to operationsYou 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:

All warehouses and operations must be linked to the same site as the production order for which the materials are needed.
An item can have several routings per site. In the bill of material (BOM), you can enter one operation number, which then applies to all routings of an item.
