DP question?

HI

what is the difference between mass processing and process chains?

[Former Member]

Process chains are created for executing multiple program(jobs), in a cycle, one after the other,

There are jobs which are dependent one after the other. for these jobs process chains are normally recommended and useful.

you use t code RSPC or even in RSA1 you can create process chains.

Hi Baji,

These terms are quite different.

Mass processing it is a term used to make reference in those cases when you execute functions for multiple objects. E.g.: in ECC you have COHV to execue multiple functions in production orders, MM17 to execute changes in the material master. So MM17 & COHV are t-code for mass processing. You can run mass processing transactions (as COHV) in foreground or in background.

Process Chains are used to set up chains of background jobs.

For example, in Demand Planning you could program a chain that uploads data from a data source to an InfoCube, generate any new characteristic value combinations, upload the data from the InfoCube to a planning area, carry out a forecast, and release the data to SNP.

Hi Baji,

During the demand planning process, planners would work with large amounts of product/location combinations. This number can increase further through the use of other characteristics. An interactive execution of the complete demand planning process is thus not possible.

To simplify and speed up this process, many of the steps will be performed in a batch or background job that processes many different characteristic value combinations one after another. SAP refers to this process as mass processing.

Process chains on the other hand as name suggests is sequence of chained processes that are designed to carry out specific task. It allows for automation and visualization of processes by using network graphics.

Process chain would help not only in DP mass processing jobs but also various BI related tasks - Loading data to cube, Nightly backup etc.

Also please have a look at below document which explains how to create DP Mass processing jobs and schedule them via process chains -

Hope it helps you.
