Alternative sequence

Alternative sequences contain operations that replace the operations in the standard sequence. They are used for example if

  • the production process in the order is changed for certain lot sizes or
  • alternative capacities are available that can be used as alternatives in the case of capacity bottlenecks

    Now in the following screen shot it describes the standard sequence of Operation and the alternative sequence of operation.

    Alternative Sequence of Operation is valid for the lot size 500 to 99999999. the branch operation is 0030 and the return operation is 0040.

    Standard Sequence of Operation

    Alternative Sequence of operation

    Graphical Overview of Operation

    So the above screen shot shows that the product can be produced either using the standard sequence of operation 0010–>0020—>0030—>0040—>0050 or else

    using 0010—>0020—>0035(single operation in the alternative seq)—>0050(Thread Cutting).

    Production Order Creation

    Ensure in the Order type dependent Parameters the necessary configuration setting is included for the alternative sequence and in the below screen shot

    sequence exchange value is set as 1-Always Automatic selection by lot size of alternative sequence.

    Now in the below screen shot the order quantity is entered as 600,

    In the operation overview of the production order the system automatically copies the sequence of operation as 0010–>0020—>0035—>0050.

    Similarly for an order quantity of 100,the system copies the standard sequence of operation, that’s 0010—>0020—>0030—>0040–>0050.

    Scenario 2:

    In case if in the alternative sequence no lot size is maintained means(default from 1 to 99999999) then in the order type dependent parameters maintain the value

    for sequence exchange as 2 – Manual selection,then during production order creation, the system issues the following popup to choose the sequence of

    operation.

    If No is selected means, then the system copies the standard sequence of operation and if Yes is selected then the alternative sequence of operation gets

    copied into the production order.

      Hi Mangalraj,

          Again a good one. It is very helpful for new learners like me.

      Thanks for sharing. It will be very appreciative if you can add parallel sequence also in this blog or can create another blog.

      Regards

      Kalyan

      Hi Mangalraj,

      Amazing document..I am a great fan of you….really helpful…at the same time include information on Parallel sequence or create a new one on this….Thanks for sharing the document….

      Hi Mangalraj,

            Thanks for sharing this document. How standard cost will be calculate if we use alternative sequence in routing while run standard cost? Whether it will be considered standard operation sequence or alternative sequence? where we have to define this settings?

      Thanks

        My sincere thanks to Anupam Sharma,Kalyan,Senthilkumar, K Kumar and AKS for adding

        your comments.

        I will include the parallel sequence of operation in this blog itself and will keep you posted.

        when it comes to costing,in case if the alternative sequence is defined for a specific lot size

        for example from 500 to 99999999,then when standard cost estimate is carried out and if

        the lot size is entered as 500 in CK11N or the which is relevant to alternative sequence then

        the system will pick the alternative sequence for costing purpose.(But ensure your costing

        variant has the proper setting which considers the alternative sequence).

        Regards

          HI Mangalraj,

              Thanks for your reply. If we haven’t mainatain any lot size  ( by default 1 to 99999999 ) how the system will decide the operation sequence for the costing run? I assume that system will consider the very first one by defualt. Could you please confirm?

          Thanks

      Hi Mangal,

      Thanks for sharing the concept. Its really great effort, appreciated!!

      I can able to recall this though I moved to other module (PLM).

      Thanx for sharing!

      Do you have a hint for me?

      I use alternative seq. Everything working sofar.

      But when printig, wrong seq number is printed in title (seq 0, standard-seq).

      The operations are though the correct ones.

      Hi Mangalraj,

      Great article! I appreciate the efforts you took to compile this. Could you please throw some light on whether this works when CIFed to APO?
