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 Standard Sequence of Operation

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).

Rate Routing – Parallel Sequence of Operation

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.

    Good one Mangalraj.

    Sharing my 2 cents here. 😐

      Why an alternative sequence is not designed in REM or with rate routings?

    The name rate routing says it all. In Production terms ‘THROUGH-PUT RATE’. Time required to make and push things across. In REM this rate is uniform and hence there is no business reason to use alternative sequence.

       In Discrete setup this throughput rate can differ based on Lot sizes (the screenshot here shows the lot size details) and it makes a valid point to define an alternate sequence in routings.

    Hi Mangalraj,

    Thanks for the blog. Appreciate if u can also share us some screens of  Product Cost collector where only Standard/Parallel sequences are referred so that it  becomes very clear to all of us.

    Thanks again for the blog.

    Hi Mangal,

    Now it is cleared why SAP experts recommend to follow for the rate routing in REM Scenario,

    it is good one,

        Hi Mangalraj,

        Thanks for this blog. I had posted a query on “Regarding PP Scope in GATP”, can you please provide your insights to my query. Sorry for mentioning this request in this blog. Thanks.

    Hi,

    Really a useful blog. I’m not having PP background, still understandable. I’m working in a REM industry and this would be really helpful for me.

    Regards,

    Sudeep.

    hi Mangalraj,

    Cool stuff. In sap standrad REM process, there is no production order but instead planned order is used for production control, for the planned order no confirmation exists. I think this is the reason why backflush is not able to choose an alternative sequence because it has no idea whether the alternative sequence is choosen or not.

    Hope my understanding is correct.

    cheers

    Hi,

    Now I am cleared about this concept.

    But one more question, we use PCC and production version for production order also.

    Then, what is difference in that.

    Thanks

    Hi Mangalraj,

    Very clear explanation.Customer always asks, why there are two ways of modeling operations & this blog will help answer some of them.

    Thanks for sharing knowledge.

        Hi Mangalraj,

        I have one query in SAP QM module, I searched a lot, not able to get correct answer, hence sending you message as I understand your explanation clearly.

        My client want to record vendor certificate details in the system.


        Steps :

        1. Vendor will send material with quality certificate against PO.

        2. GR will be done through MIGO.

        3. Inspection Lot created automatically.

        4. In house inspection done.

        5. Result recording done.

        6. Usage Decision done.

        In inspection report, we get in house inspection recordings, But my client wants to enter vendor quality records which has been sent by vendor with material so that they can analysis inhouse quality records and vendor quality certificate records. I have read about QC51 but not able to understand it properly, kindly if anyone can explain me clearly how we can handle this situation.

        Thanks

        Navin Raina
