Before you can synchronize block storage outlines, you must determine which outline is the source outline and which is the target outline.
By default, the source outline is from the same database as the data source; that is, outline and data changes flow in the same direction. For example, if the East database is the data source and the Company database is the data target, the default source outline is East.
You can also use the data target outline as the source outline. Consider this method if the structure of the outline (its dimensions, members, and properties) is maintained centrally at a corporate level, while the data values in the outline are maintained at the regional level (for example, East). Administrators can make changes in the Company outline and apply those changes to each regional outline when the outline is synchronized.
If you make changes to the shared area in the source outline, you can propagate them to the target outline when you synchronize the outlines.
If you make changes to the target outline, those changes cannot be propagated back to the source outline when you synchronize the outlines. To move these changes up to the source outline, make those changes in Outline Editor. See Creating and Changing Database Outlines.
Essbase updates as many changes as possible to the target outline. If Essbase cannot apply all changes, a warning message prompts you to see the application log for details. Messages that pertain to outline synchronization are prefixed with OUTLINE SYNC. See Viewing the Essbase Server and Application Logs.
To set the source outline, see Setting up the Data Source and the Data Target.
