Using parallel processing functions, you can significantly shorten the runtime of the total planning run. For parallel processing, you can also choose to use various sessions on one server or to use various servers.

In Customizing for MRP, you have made the necessary settings for parallel processing in the IMG activity Define parallel processing in MRP, that means, you have defined the corresponding destinations (application servers) with the number of sessions available.

Parallel processing is carried out on the basis of the low-level code logic:

A package of a size to be determined is distributed per RFC (Remote Function Call) to the individual server/tasks. Once a task has completed processing one package, the next package of the same size is processed. Once a low-level code is completed, the finished tasks must wait until the last package is also complete in order to avoid inconsistencies. Then the next low-level code is processed package by package.

You can use parallel processing for the total planning run online as well as a background job. It is activated in the initial screen.
