About comparing data in a sharded environment using the CDT
If you are comparing data in a sharded environment, the CDT displays an Input pop-up window prompting for the Colony ID to compare.
If you click the OK button without entering a Colony ID, the CDT compares all colonies.
When you enter a Colony ID and click the OK button, the CDT compares data only for that colony, which is the set of organizations that belong to the colony. If you have other colonies in your configuration schema that you want to compare, you must compare each colony separately. For example, you must compare Colony_01 and Colony_02 in separate comparisons.
If you are comparing data in a master data schema, CDT displays the Input pop-up window instead of displaying a prompt for the Colony ID. This is because the master data is the data of an entire colony.
When you enter the name of an organization in the Input pop-up window, CDT compares only the data of the organization that belongs to the particular colony.
If you click OK without entering an organization in the Input pop-up window, CDT compares all the colonies.
