Create Object Links Cache

This workflow uses the Create Object Links Cache action to create a tree of object dependency links for the specified RFC Destination. The tree of object links is stored in an Object Links Cache database on the drive where the LiveCompare user data directory is stored. Additionally, for any objects with code that need to be refreshed, SAP’s cross reference tables are rebuilt using a custom function.

If an Object Links Cache database does not exist for the RFC Destination, a new Object Links Cache database is created from scratch. If an Object Links Cache database already exists, it is updated to include any newly-found object dependency links. Typically, this is a much faster operation.

The Create Object Links Cache workflow should be run before the BW Change Impact Analysis and Object Change Impact Analysis workflows from the Impact Analysis package are run against an RFC Destination for the first time. Running this workflow provides the object links cache database used by the Find Object Links, Find Similar Objects, Uses What and Where Used actions.

Creating RFC Destinations

Before you begin, you will need to create an RFC Destination for the Analysis system.

Preparing the Workflow

To prepare the Create Object Links Cache workflow, drag its workflow template from the Templates folder into your own workspace, and modify the workflow as follows:

  1. Select the Analysis System parameter and choose ‘Edit RFC Destination’ from its context menu to display the RFC Destination dialog.

  2. Select the RFC Destination for the analysis system, then click ‘Save’.

Save the workflow using the ‘Save’ toolbar button.

Running the Workflow

To run the Create Object Links Cache workflow, click the ‘Run’ toolbar button, choose ‘Run Now’ from the diagram’s context menu, or press F5. The currently running workflow action is marked with an animated display. When the workflow execution has completed, select the Result dataset and choose ‘View Details’ from the context menu to verify that either a Full Cache Update or Incremental Cache Update has been performed.

Usage Scenario

The Create Object Links Cache workflow should be run once to perform a Full Cache Update each system to be analyzed using any of the following Apps or template workflows.

Apps

Templates

The Create Object Links Cache workflow should be run again on any system whose analysis objects may have changed (for example, after support packs have been applied, or after changes have been migrated from another system), This will perform an Incremental Cache Update to ensure that the system’s Object Links Cache database is up to date.
