Delete a codelist subset
- At the bottom of the Project Explorer, click the Codelists () button.
- Expand the Codelists folder, select a codelist, and then select the Subsets tab.
- In the grid at the top, highlight the row for the subset you want to delete by clicking the box on the left.
- Click Remove and confirm the deletion.
Tip: To locate the item instances that use the codelist with the deleted subset, generate an annotated study book and look at the Codelist Values tables.
