Prefix syntax validation rules

The validation rules for the prefix syntax are:

• The prefix can only be two characters long.

• The characters in the prefix are not case sensitive.

• The first character must be an alphabet (A-Z).

• The second character can be alphanumeric (A-Z, a-z, or 0-9).

• Special characters are not allowed.

  Some of the incorrect prefix examples and the error messages are listed below.

  Prefix Syntax	Error Message
  Contains more than two characters Aa1 Z4Ab	Length should not be more than two characters
  First character not an alphabet $A 1B	Please input valid input prefix
  Prefix contains a special character A$ %B %&	Please input valid input prefix

  Note: The maximum length of the template is 32 character. However, if a prefix is added, the maximum length of the template is 29 characters (Prefix_template name : 2+1+o29).
