To add character restrictions to an item

  1. Go to the Item Subclass > Restrictions property.
  2. Choose Character from the drop-down list.
  3. The restriction list is case-sensitive by default. If you do not want case-sensitivity, set the Ignore case subproperty to Yes to ignore case.
  4. Set the Rule subproperty to Include or Exclude the values that you will provide.
  5. Enter the character restrictions in the Include First or Exclude column.
  6. Enter corresponding values in the Include After or Reference String column.
  7. Analyze the schema.
  8. Save changes.
