The business object master recipe is the description of an enterprise-specific process in process industries, that does not relate to a specific order. The master recipe is used for the manufacture of products or for rendering services.

A master recipe consists of a header and several operations, each of which is carried out at a primary resource. An operation is subdivided into phases.

A phase is an independent process step that contains the detailed description of a part of the entire manufacturing process. Phases are carried out at the primary resource of their superior operation.

The way phases are related to each other specifies the sequence of the manufacturing process. Phase relationships can be sequential, parallel, or overlapping.

Several materials required for the execution of a specific process step can be planned for an operation or phase. These materials must be components of the BOM for the material to be produced.

A phase contains standard values for activities. These values serve to calculate dates, capacity requirements, and costs.

Several secondary resources can be planned for operations and phases in addition to the primary resource.

Several inspection characteristics can be defined for each operation and phase for inspections during production.

In addition, you can plan production resources/tools (PRT) for operations and phases. You can assign one of these PRTs as test equipment to each inspection characteristic.

A phase contains a number of process instructions that convey information relevant to process control.

Master recipes are assigned to a plant and are part of a plant-independent recipe group.

In the recipe header, master recipes used for production are linked to the materials to be produced. The production versions of the materials also link them to the alternative BOM required for production.

Master recipes are used as the basis for process orders.

During order processing, the process instructions of a phase are transferred to the control recipe destination that requires the information for process control.
