Starting with SWAT 20.05 version, you can use regular expressions definitions to specify the format of a character field. The definition is added in the 'extendedFormat' attribute in the designer.

We support static masks, dynamic masks and Regex expressions.

Masking definitions:

• 9 - numeric
• a - alphabetical
• * - alphanumeric

Exampled for the extendedFormat attribute on character fields to specify the format:

• extendedFormat: aa-9999
• extendedFormat: aa-9 {4}
• extendedFormat: regex:[0-9]*
