Manage groups for Mapping transformations

Mapping groups define the rules to apply to tabular data with Mapping transformations in pipelines. From Mapping groups library_books, you can manage the mapping groups available for use with pipelines.

Edit a mapping group's column definition

A mapping group's column definition includes:

• The primary column, which contains the values changed by the Mapping transformation
• Any additional columns with values to consider for conditional mapping rules

To edit a mapping group's column, on the Columns view_column tab, click Edit columns, and update its data type or name as necessary.

To add a new column to the mapping group:

1. On the Columns view_column tab, click Edit columns.
2. Under Define columns, click Add column.
   
3. In Data type, select the type of data in the source column to transform.
4. Enter a name of the new column.
5. Click Save.

To use the updated columns with Mapping transformations, click Publish.

Edit a mapping group's rules

To add or manage the rules a mapping group applies to tabular data, select its Rules gavel tab.

Copy a mapping group

To create a new mapping group with similar columns and rules as another group, start with a copy of the existing group. 

1. From Mapping groups library_books, click Copy file_copy for the existing group to create a duplicate.
   
2. Edit the name of the duplicate group, and click OK.
3. Update the columns and rules of the new group as necessary.
4. To use the new group with a Mapping transformation, click Publish.

Archive a mapping group

If you no longer use a mapping group, archive it as a read-only version, such as for audit requests:

• From Mapping groups library_books, select the Active tab, and click Archive archive for the group.
  
• In the mapping group, select Archive from its menu.
  

To return an archived group to Active status, on the Archived tab, click Restore for the group.

Delete a mapping group

Note: When you delete a mapping group, you can't recover it. To download a CSV of a group's rules as a backup before you delete, click Download on its Rules tab.

To completely remove a mapping group and its history:

1. From Mapping groups library_books, archive the mapping group if necessary.
2. On the Archived tab, click Delete delete for the group.
3. In Confirm, enter delete.
4. Click Delete.
