Sequences group together operations in the order. Operations in a sequence are processed according to their place in the sequence. Sequences are linked in network-like structures.


The following types of sequence exist in the SAP System:

  • Standard sequence

A standard sequence is the first sequence of operations that is created in the routing or production order. If all of the operations are to be processed sequentially in an order then only a standard sequence is required for this order. If certain operations are to be executed as alternatives to or parallel to part of the standard sequence then they must be grouped together as alternative or parallel sequences.

The operation in the standard sequence at which a parallel sequence is to start or from which the standard sequence is to be replaced by an alternative sequence is known as the branch operation.

The operation in the standard sequence after which a parallel sequence is to branch back to the standard sequence or up to which an alternative sequence is to replace the standard sequence is known as the return operation.

  • 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

Note Note

Alternative sequences cannot be changed or added to the production order.

End of the note.
  • Parallel sequence

A parallel sequence runs parallel to the operations of the standard sequence. The start of the parallel sequence corresponds to the start of the branch operation in the standard sequence. The end of the parallel sequence corresponds to the end of the return operation.

If parallel sequences exist in the routing selected then they are automatically copied to the order when the routing is exploded.
