Programming with the CSL

Use

You can use the CSL to realize two elementary application cases:

• Cross-System Lock (within an LUW)

• Cross-Transaction Lock (possible for multiple LUWs)

The lock objects (the CSL tokens, that is) are independent of each other. This means that there are no interdependencies when locking, referencing, or moving two tokens. The application cases in this section therefore look at exactly one lock object.

Prerequisites

For both application cases, the CSL must be activated, and every token must be assigned to a lock object type. You can also activate the CSL for certain lock object types only. The necessary RFC connections must be set up (see also: Customizing Settings).
