1. From the Applications menu, select Custom Table Manager
2. Under Custom Hierarchies, navigate to the custom product hierarchy to edit and click Edit
3. Make any desired edits directly within the spreadsheet view in the right-hand pane
5. (Optional) Click Validate Entered List to ensure that all values in the first ("lookup") column are valid
6. When all edits have been made, tick the Replace checkbox and click Save
Editing directly within the table manager is generally advised for minor or limited edits. To make major changes to a custom hierarchy, it may be best to use the 1010data Excel Add-In to re-upload the custom product hierarchy template.
