REFERENCE_INFO is a 50-character alphanumeric optional field used throughout the application to provide users the ability to enter additional reference information.

When used in IPSN this field allows users to enter a note or reference for the sundry. This reference information may be either anecdotal or more structured (e.g. Union Code or Court Number). If the Reference field on IPPC is defined as 'Enter Vendor Code', users will select a code from an LOV. If there is no link, users may use this field to provide a description directly on the IPSN screen. Users will be able to enter up to 200 characters as reference on the pay lines. This entry will not be checked against values within any lexicon.
