Making bulk changes to term, data class, and classification assignments
After reviewing term, data class, and classification assignments in the metadata enrichment results, you might want to change assignments for more than one asset or column at once.
Changing term, data class, or classification assignments
You might want to assign specific business terms or classifications to more than one asset or column, or you might want to remove business terms or classifications from several assets or columns because they don't fit. You also might want to change the assigned data class for a set of columns or even remove data class assignments completely, for example, for all columns of a specific table.
Depending on the volume of changes, you might see a success message for the bulk operation before the changes are actually complete. You might need to refresh the view several times before you see all changes applied.
- Required permissions
- To change assignments, you must have at least the Editor role in the project, and you must have at least view access to the categories that are used in the enrichment.
You can also perform these tasks with APIs instead of the user interface. The links to these APIs are listed in the Learn more section.
