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.
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.
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.
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.
