How to use Process Step Library (PSL) items

The PSL is one of several libraries that are introduced with SAP Solution Manager 7.2.

Process Step Library

The PSL contains process steps (PSL items) and attached documents, test cases etc. Each business process step used in a branch must refer to a PSL item. Other business process steps can reference the same PSL step. In ARIS, the PSL is downloaded into the PSL folder of each branch. A relation is created for each business process step and its corresponding PSL step.

Reuse of PSL steps in business processes

Base process steps can be defined as PSL steps. They have individual names and descriptions, assigned executables, related roles and specific documentation. These PSL steps can be reused in other processes. A best practice is to use a standardized process framework to structure the PSL.

Reuse PSL objects

Example

In process A you are going to use the PSL step as defined. So you just reference this PSL step from the PSL to the business process step. In process B the business process step is slightly different. For example, an additional role and a document are required. Hence, at your business process step you add the new role, change the description and add a new document. It is still based on the PSL step, but has different roles and documents assigned. When selecting the business process step you will see the properties of the base PSL step together with the properties of the business process step. When creating SAP functions, you can define the master object to be used.

Process step properties

In Solution Manager 7.1 projects, you might have connected several transactions to one process step. SAP best practice for Solution Manager 7.2 recommends the use of a one-to-one connection between PSL steps and executables.
