What action on the Data Maps page is required to see metadata changes immediately after changing dimensionality in a target cube?

When changes are made to dimensionality in a target cube, it is essential to refresh the database to ensure that those changes are immediately reflected in the data maps. By selecting the corresponding data map and choosing the option to refresh the database, the system will update all related metadata, which includes any alterations made to dimensions. This action ensures that the data integrity is maintained and that users have access to the most current version of the data structure.

The alternative choices do not accomplish the same objective as efficiently or directly. For instance, executing the Synchronize Defaults Business rule might update settings or default values but would not guarantee that all metadata changes are reflected immediately. Similarly, synchronizing or executing the Synchronize Components Business Rule might involve updating aspects of the cube or mappings, but again, it does not focus specifically on the immediate display of metadata changes resulting from dimensionality adjustments.
