Triggering Delta Merge via Process Chain

In certain exceptional cases, performing a delta merge after processing a DTP request is not recommended, due to load balancing issues. In this case, an alternative method is to trigger the delta merge via a process type.

Context

In exceptional cases only, which result in load distribution problems, we recommend deselecting the checkbox in the DTP and using the Trigger Delta Merge process type to trigger the delta merge. An example of this is an object that data is loaded into from multiple sources. The delta merge check is only performed at the end of the entire loading process.

Note

Make sure that the DTP or process type always triggers a delta merge. If no delta merge takes place, the data remains in delta storage. Over time, this will result in storage problems and have a negative impact on read performance.

Procedure

You are in the plan view of the process chain where you want to include the process. Process type Trigger Delta Merge is available in process category Load Process and Post-Processing.

Drag and drop process type Trigger Delta Merge to a suitable position in the process chain.
A dialog box appears. To create a new process variant, choose .
In the next screen, enter a name and a description for the process variant and choose .
On the process variant maintenance screen, specify the type and name of the object for the delta merge.
Save your entries and return to the plan view for the process chain.
Link the process to the required loading processes.
