Field Code Format on the form of customer/vendor groups (tab General) allows for specifying rules according to which the code of customer/vendor added to a given group should be defined. If a customer/vendor group has a code format defined, then, on the basis of that code format, when adding a customer/vendor to the group, the system verifies the correctness of the code assigned to that customer/vendor by the user.

The code format is created according to the following rules of RegEx syntax:

• First, is necessary to enter a special character which defines type and interval of characters uded in the code, e.g.
  • [] − indicating an element from a list
  • () − remembering the content in brackets as an item,
  • $ – meaning the end of a row
  • ^ – adjusting to the field beginning (a character following ^ must be the beginning of an expression)
• Then, if the code is supposed to contain numbers, quantity quantifiers are used, e.g.:
  • \d − any number of digits
  • \d? − zero or one digit
  • \d − one digit
• In order to use a white space (e.g., a space), it is necessary to add \s between expressions
• The remaining characters are entered permanently into a code format (i.e., aa\d indicates that these codes can only be in the following forms: aa1, aa2, aa3, etc.)

Basic RegEx expressions:

Expressions Defining Possible Character Types

Expressions defining a number of repetitions of a given expression

Exemplary use of RegEx Code Format:

A code format can be also a part of a configuration tool, however, in such case, the following expressions are not handled:

• expressions containing special characters:
• \d
• \w
• \s
• *
• +
• {n,}
