Often, many industries like FMGC, chemical, pharmaceutical, etc use multiple similar resources to manufacture a product.

E.g. A plant has many mfg bagger, or filling lines with identical capacities. A product is chronologically said to be manufactured in bagger 2. Alternatively this product also can be manufactured in bagger 3 or bagger 4 if needed. On shop-floor business cannot determine the primary resource to be used until shortly before order processing. But in mid to long term planning, they want to assign a suitable planning resource to the operations provisionally.

The constraint for long term planning needs to be on planning resource. In short term the flexibility needs to be given for resource selection based on SKU. This can be mapped in different ways in SAP.

1. By multiple production Versions with multiple master recipe

This method is most widely used but requires laborious master data maitainance as one recipe has to be created explicitly for each resource and has to be assigned to one production version respectively.

2. By manual selection in the Order.

The resource is changed manually on the Order. This change requires a single approval process if ECM to be used. Production Planners will feel as more work and any change which needs a Quality Approval in GMP environments will take more time to create and release the order for production.

3. By Resource Selection through classification.

SAP provides another way of maintaining this alternate resource selection by using resource classification.

We can use a planning resource as the primary resource and select the alternate resource through the resource network maintained through work center classification (type 019). This also works well with ECM and is a good option for Planners as there is no need of Single Approval from QA personnel.

Create a Characteristic (T-Code CT04)

We can create classifications in ECC for suboperations and secondary resources.

In Additional data tap define Table Name as CRHD and Field Name as ARBPL.

Create Class and assign characteristics to class T Code: CL02

Assign classification in ressource T Code: CRC1 or CRC2

All relevant alternative work centers must contain exactly the same classification and characteristic value assignment. Work centers with different classes or characteristic values are ignored.

Assign the classification in master recipe and add alternate resources T Code: C201 or C202

Create process order COR1 or By MRP Planned order to Process order

On the operations tab, select the operation 10 and click on Resource selection condition

Product can be produced on all 3 lines here you can select the resource accordingly.

Capacity Planning CM25

We can change the resource from this screen by dragging and dropping it to another resource from the resource section.

Resource classification automatically creates multiple modes in APO PDS or PPM, so it can be used in PPDS while converting SNP Plan orders to PPDS plan orders. And in DS board we can schedule the order on required resource.

If we want to use different capacities for planning, but for execution purpose we only want to use one resource. So from many lines in mid term planning to accommodate constraints, but for short term we use single resource for production execution.

    Hi Rupesh,

    Thanks for sharing your knowledge, We have been struggling with the previous two options in our projects with same problem.

    Great work.

    Thanks For sharing , Very Helpful document. Is it Possible that this functionality is possible in Discrete manufacturing..? Like in Textile , In weaving operations there are more than 50 Looms and they decide during the Production order generation.

    Hello Rupesh,

    Thanks for this very useful Shared Doc,
    Is it will also helpful in Discrete ? as one our client also do the same activity while confirmation only.

    Best regards,

      Hi Sujeet,

      Thanks, In Discrete manufacturing you can use the parallel or alternative sequence in routing.

      and while confirmation you can select alternative sequence.

          Hii Rupesh,

          We are using classification 19 for grouping of alternative resources, and then doing planning in APO. It moves as  a single PDS with multiple modes.

          The planning is perfect, and we never faced any problem, But recently we have started WMS, where we got the issue that Though APO Shows planned order/production order for particular Resource based,  But when it comes to ECC it doesn’t show the correct resource for the planned order/production order.

          The Production order in ECC side does not give the correct information of resource. Even in the report COOIS , in the column production line , it doesn’t show the correct information as per planned in APO.

          Is it possible to get the correct information resource in ECC side for the orders ?

          Regards

          Debashis

            Hi Debashis,

            I really don’t have any idea about resource classification with WMS. You many raise this issue to OSS. Also update the solution over here.

            Many Thanks,

    Dear Rupesh,

    Thanks. Document is very informative and actually I am on a Implementation Project where 200 Reactors( Resources) and their usage unpredictability were creation a chaos and I was Struggling.

    Perhaps, one more way could be from Standard SAP customization of Single Entry of Confirmation OPK1 where we can create an alternate Profile encapsulating Actual Resource. At the time of Process Order creation, default Resource will be used but at the time of Confirmation, Actual resource will be Capitalized.( Bottom of COR6N screen)

    Next screen Looks like this

    Click on preview will navigate to next screen.

    There will be Actual resource from where we can confirm the Order. All the Activities will be loaded from default resource to Actual Resource. And Variance can be analyzed as Resource Usage Variance in Controlling.

    Regards

    Shailesh

      Hello Shailesh,

      This is really a good option too. Please create a document and post it on SCN. It will be helpful to everyone.

      Thanks,

    Dear Rupesh,

    In comments, you have mentioned that Work center classification is too applicable in Discrete Industry. I tried and tested the results but while assigning the multiple work centre in Routing, it is not accepting. Though multiple Work centers do appear in operation but you cannot this concept in Discrete industry. You may also test this and correct me if I am wrong.

    Best Regards

      Hello Shailesh,

      As I know it should work, could you please let me know what the issue you are facing?

        Dear Rupesh,

        Class and characteristics created for 3 work centre WC1, WC2, WC3 and in Cr02 assigned the class.

        Now, while assigning classification to Operation 10, Not all 3 work centres are getting assigned.

        When you are about to assign multiple Work centre to Op-10, this functionality is missing in discrete as system allows to assign only 1 work centre to operation.

        Please correct me if I am wrong.

        Best regards

        Shailesh

          Hello Shailesh,

          This could be due to Characteristic only allowed for Single value.

          Go to CT04 enter your Characteristic in Basic data Choose Multiple value radio Button.

          Then again assign class RESOURCE_ALT to your work center system will allow you multiple work centers.

          Best Regards,

            Dear Rupesh,

            100% correct. It worked as you said. Thanks a lot once again for clearing my doubt.

            In discrete industry, we too can use Resource selection Condition for Operations.

            Best regards

            Shailesh

    Hi Rupesh,

    We are using resource network for the same requirement.

    Is there any way to restrict the change of resource in Capacity Planning (CM25) to another resource that not in the classification?

  7. TRAORE TIDIANE

    Hi Rupesh,

    Is there a way (usex exit or function) to update standard values of operation when changing the work centre? To be clear how to reschedule operation(duration of operations)  when alternatives ressources have not the same speed ?

    thanks for your help

      Hi Traore,

      Did you find any solution or a work around for Alternate Resources having varying Speeds?

      Thanks & regards,
