Performance Impact of Blueprint Changes

Certain changes to Business Objects may cause database tables to be rebuilt during the publish process. This can extend the amount of time it takes to complete the publish process, especially for Business Objects that contain a large number of records. This may impact system performance and cause some Business Objects to be unavailable.

For example, certain changes made to the Journal Business Object may cause a table rebuild, which can prevent users from accessing Journal records in related Business Objects, such as Incidents, during the publish process.

Business Object Changes

Changing the primary key for a Business Object will cause a table to be rebuilt.

Field Changes

The following changes to fields will cause a table to be rebuilt.
