You can delete custom fields that you created. Custom fields begin with
u_. It is recommended that you remove the field from forms and
lists instead of deleting it.

## Before you begin

Role required: admin

## About this task

You cannot delete base system fields. In addition, any missing base system fields are
recreated when the instance is upgraded.

## Procedure

1. Navigate to a form that contains a custom field to delete.
2. Right-click the field label and select Configure Dictionary.
3. Click Delete Column in the form header, and then click OK.
4. To delete multiple custom fields, complete the following steps.
   1. Navigate to System DefinitionDictionary.
   2. Locate the custom fields to delete.  
      For example, search for column names that start with <kbd class="ph userinput">u_</kbd>.
   3. Check the boxes next to the fields to delete and select Delete from the action list below the list.  
      A confirmation dialog opens and reminds you that this may result in deletion of related records. If there are dependencies for the selected fields, they are listed.
   4. To proceed, click Delete.
