The field type selected in the Add Field dialog box determines the available field settings. The default choice is Auto-generated Sequence.

Auto-generated Sequence Settings

• Use to Name text box to give a name to the auto-generated field.
• The length determines the number the size of the range field and must be a positive value.
• The range specifies the beginning and end of the auto-generated number. The lower most limit must be less than the upper most limit.
• StepSize controls how the auto-generated number is incremented.

Delimiter

• The value must be a character. The delimiter is used to separate fields.

Fixed Text

• Use the Name text box to give a name to the fixed text field.
• The value entered in the Fixed Text field always displays in the file number and cannot be modified by the user.

Free Text

• Use the Name text box to give a name to the free text field.

• Max Length controls the maximum number of characters allowed for this field.

• Max Length required forces user to enter the number of characters specified in the Max Length field.

• When free text is used with an auto numbering scheme, the numbering only increments if the free text is identical. If the free text changes, then the auto number resets to the first number in the series.

  For example, if an auto-numbering scheme is set to 1-100 with a free text entry, and a file is renamed using the scheme, the auto number will reset to 1 unless the free text remains the same. For instance, is a file named 1-file.txt is renamed as <autonumber>-new-name.txt, it will become 1-new-name.txt.

Predefined List

• Use the Name text box to give a name to the predefined list field.
• Specify a list of values in the Code field. You can optionally enter a description for each of the values.
• Use the Move up and Move down buttons to change the order of the values.
• Use the Delete button to remove a value.

Workgroup label

• Selecting this option automatically assigns the workgroup label as a fixed value in the numbering scheme.

Character Limits

Numbering schemes have specific character limits:

• Prefix: Up to 50 characters
• Suffix: Up to 50 characters
• Auto-generated number: Up to 9 digits

The prefix and suffix can contain any combination of Delimiter, Free Text, or Fixed Text fields. However, if the combined length of all elements in the prefix or suffix exceeds 50 characters, an error occurs.

Maximum file name length: 109 characters (50-character prefix + 9-digit auto-generated number + 50-character suffix)

Note: This limitation exists because the database fields for both prefix and suffix are each restricted to 50 characters. If you need longer prefix or suffix values, you must update the database schema to support larger field sizes.

Unrecognized characters

• The following characters are not acceptable in file or item names: " / ? < > \ * | :
