Nested Parallel Routings in Production Orders

In the routing transaction (CA01) there is a reference sequence field on the sequence detail screen. Use of the field allows parallel sequences to be created that return back to a sequence other than Sequence 0.

In the production order transaction CO01 the reference sequence field in not available on the sequence detail screen for production orders.

A production order created using a standad routing (type N) that includes a parallel sequence defined with a reference sequence field value other than 0 (main sequence) fails to import correctly. Parallel sequences that have a reference sequence field value of 0 import correctly. There is no error message or warning.

We are on R/3 4.6B and upgrading to ECC 6.0. The problem exists in both versions.

    Dear Kelly

    A standard sequance ' 0 ' can have a parallel or an alternative sequance say 1 and 2. First you have to define a parallel sequance to standard sequance. then you can define additional parallel sequances to the one defined first. this will import the parallel sequances correctly.

    I created a standard routing with seqence 1 that refers back to sequence 0. I then created sequence 2 that refers back to sequence 1, not sequence 0.

    The standard routing is selected for use in a production order. Sequence 0 and sequence 1 are in the production order routing, but sequence 2 is missing.

    The key to this problem is in compare the "sequence detail" screen of a standard routings to the "sequence detail" screen in a production order routing.

    You will find that in a standard routing the "Reference" section contains three fields in the following order - "Ref. sequence" (reference sequence), "Branch operation", and "Return operation".

    Now look at to the production order "sequence detail" screen. In the "Reference" section there are only two fields - "Branch operation" and "Return operation". The "Ref. sequence" (reference sequence) field is missing.

    The production order routing "assumes" that all parallel sequences return to reference sequence 0. A sequences defined in a standard routing that does not return back to sequence 0 will be dropped when imported into a production order routing. In this example sequence 2 of the standard routing contains a value of 1 in this field. The system does not recognize sequence 2 in the production order because the reference sequence field is missing from the production order seqence detail screen.
