Standard validation method

Use the Standard validation method to restrict the length and number of characters in a field.

Configure a standard validation method

  1. On the Type list, select Standard. (Default: Regular expression)
  2. Configure the following Options.

    Rules make uncertain extraction results valid

    If selected, overrides the execution of validation rules when a field is not extracted confidently or has been modified. (Default: Clear)

    Check for minimum length

    If selected, lets you enter or select the minimum number of characters allowed for the result. If an extracted result is shorter than the minimum length, the field is marked as invalid. (Default: 1)

    Check for maximum length

    If selected, lets you enter or select the maximum number of characters allowed for the result. If the extracted result is longer than the maximum length, the field is marked as invalid. (Default: 10)

    Restrict allowed character set

    If selected, lets you enter the characters that are allowed in the result.

    If a field contains characters other than the restricted set, the field is marked invalid and needs review by a validation operator.

    Define unallowed characters

    If selected, lets you enter the characters that are not allowed in the result.

    If a result contains one of these characters, the field is marked as invalid and needs review by a validation operator.

    Allow empty field if other options are chosen

    If selected, allows an empty field to be valid; otherwise, the empty fields are marked as invalid.

    Note This option is only available if one of the parameters is selected.

  3. To test the standard validation settings, enter sample text in the Test input text field and click Validate.
    A message appears to inform whether the rule is valid.
  4. Click Save.
