The Order Attribute Format Transformer rule allows you to append prefixes and suffixes to order attributes. For example, you can create a rule to add "INV-" to the beginning of every Order Id.
The parameters of this rule are:
Attribute Name - A select list of attributes of an order which can be used to filter, e.g. Shipping Country
Prefix - The value prepended to the beginning of the original attribute value, e.g. INV-
Suffix - The value appended to end of the original attribute value, e.g. 000
