When you configure any business intelligence resource except a Microsoft Analysis and Reporting Services resource, you can choose to incrementally load recent changes to the metadata instead of loading complete metadata. After the first successful load, the Metadata Manager Agent incrementally loads metadata that changed after the last successful load.
Data Source Changes
New metadata is incrementally loaded when any data source change occurs after the last successful load. The following list describes some examples of data source changes:
A report is added in a report folder.
A report is linked to a different package or universe.
A report metric is deleted.
A report is deleted or renamed.
A report is moved to another folder.
A report folder is renamed.
An attribute object in a package or universe is renamed.
A folder is moved to another folder.
If the source data did not change since the last successful load, the load is complete.
Exception Scenarios
Even if you specify incremental extraction for a resource, complete metadata load occurs in the following scenarios:
You purge the resource.
You update the source configuration details of the resource.
You cancel the first load of the resource or the first load of the resource fails.
