Split In Routing / Difference Between Alternative And
Parallel Sequence
The term "Splitting" in SAP means having more
than one person or maching working on an operation in a production order.
SAP assumes that only one person/machine will be working on a job at a time.
If it takes one hour to make one, and the order is for 10, the system will
schedule the job at that work center to take 10 hours. However, if in the
operation in the routing, you select "Required Splitting", then you put in
"number of splits" as 2, then the system will assume you are having two
people/machines work on the job at the same time, hence it will only schedule
the job to take 5 hours, not 10. If you put in splitts as 4, then the system
will assume 2.5 hours to get the job done.
Also, sometimes it might be ridiculous to split the job. For instance, if
that previous example order was only for 2 piedes. Having two machines working
on it would be dumb, because you would have to do two setups. So the system
gives you a Minimum processing time, so if it's less than, say, 5 hours, do not
split it.
What is the difference between alternative and parallel sequence.How these
are used?
Generally in routing 3 types of sequence are present which are standard,
parellel and alternate sequence.
Alternate sequences are linked to the standard sequence which is the main
sequence. The place where alternate sequence starts from the standard sequence
is called branch operation and again the place where it joins the standard
sequence is called the return operation.
Parellel sequences are set of operation which run parellel to the standard
sequence, for example in a chemical industry for analytical processes that occur
parellel to the main production process.
Alternate sequence consists of set of operations other than the standard
sequence so that either of the sequences can be run for a production
process.Generally branch operations in the standard sequence are ingored in this
process.
