Why Rate Routing is (recommended) used in Repetitive Manufacturing?

Dear forum Members,

As I could see multiple threads posted to understand the difference between Routing and Rate routing,it seems still many members are unsatisfied or not clear

with the concept or explanation given to such threads. I thought  a blog with few screen shots can help everyone to understand the basic difference between

Routing and Rate Routing and also why Rate routing is suggested/recommended  as the Task list type in the case of Repetitive Manufacturing.

Basic Difference between Routing and Rate Routing:

In a standard routing we can create 3 different sequence of operation,

  • Standard sequence
  • Parallel sequence
  • Alternative sequence

Routing Alternative Sequence of Operation

When hitting the sequence create key in Routing the system pop to choose between alternative and parallel sequence

In a standard rate routing SAP allows us to create only

  • a standard sequence and
  • Parallel Sequence of Operation.

It is not possible to create an alternative sequence of operation in Rate Routing.

No option to create alternative sequence of operation in Rate routing(in the above screen shot).

Why SAP recommends using a rate routing in repetitive manufacturing process is because normally during assembly backflush in transaction code MFBF, there is no configuration setting or other control to choose the set of operation (Standard sequence or alternative sequence of operation) which needs to posted for production confirmation.

The standard SAP system has been designed in such a way that during assembly backflush in MFBF it can post the activities/operations cost only for the standard sequence of operation and parallel sequence of operation. So for this reason SAP recommends to use a rate routing instead of a standard routing, because in rate routing there is no provision available to create an alternative sequence of operation.

But still if standard routing is used for those products falling under repetitive manufacturing then we must ensure that only it contains a standard and parallel sequence of operation. This is because product cost collector is one of the mandatory master data for repetitive manufacturing. This PCC in turn is created with reference to the production version. This production version in turn holds the rate routing group and group counter number. This rate routing group & group counter number will be holding the set of operations (only standard and parallel sequence).

I hope the above content will help everyone to understand the basic difference between Routing and Rate Routing and why Rate routing is used more in Repetitive Manufacturing.

I kindly request everyone who reads this blog to share their views and comment on this blog by rating the same.
