Create a codelist

Codelists specify a list of valid values that you can associate with a table column.

1. Click the Navigation icon at the top of any page and then click Library.

2. Select the Codelists tab.

3. Select a project (or whatever study groupings are called in your company) in which to create the codelist.

   Tip:

   Selecting a grouping is required and can help users find the codelist. But codelists in any grouping can be used in any study.

4. Click the Add or Modify icon. (If you are modifying the codelist, you must first check it out.)

   Tip:

   Modifying a codelist creates a new version of it. When you assign the codelist to a column, the column uses the current version. Columns that already use the old version will continue to do so unless you explicitly modify the column.

   • If you want to change all columns to the new version, modify the codelist.

   • If you want to be able to assign either version to a column, create a whole new codelist with the modified list of values.

5. Codelist Name Enter a name.

6. Description: (Optional) Enter a description such as its values to help users decide if this is the codelist they need.

7. Click OK.
