You can delete items in a custom lookup table when they are no longer needed. For example, in the design stage of implementation, you might need to clean up the contents of a custom lookup table to have the associated field display the appropriate selections.
TeamConnect automatically checks to make sure that each lookup item is not being used in records. If an item is being used as data in a record, you are notified and asked to confirm your decision to delete it.
Caution: Deleting a lookup item also deletes the item's data entries in records, all of its child items, and the child items' data entries.
