Specifies valid prefixes for purchase order numbers. Used to identify purchase order (PO) invoices. Normally the financial system controls which prefixes are used.
Use this setting only for the InvoiceOrderNumber field type. (That field profile is called OrderNumber in the U.K. country profile and PONumber in the U.S. country profile. See Field type names in different languages for other translations.)
Example:
ValidPrefixes=4500
This specifies that order numbers always start with "4500". Specifying this helps the program to find the order number on the invoice.

Do not use this setting in combination with the "-" character in a format specification to remove specific characters. Example: Say the field value is 1234/45000999 and the value you want out is 45000999. If you set ValidPrefixes=45 and the format specification is -X(5)N(8), it is unlikely that 45000999 will be found, because ValidPrefixes makes the program search for 45, but the string begins with 1234. Do not use ValidPrefixes in a case like this. Instead, use this format specification (for example): -N(4)-X[/]{N[4]|N[2]|N[7]}N(6) |
Prefixes that can be present in purchase order numbers. Include numbers, letters or special characters. Do not use spaces. Not case sensitive. A comma must separate each prefix.
