The MS Access database provides suppliers with valuable information on all messages sent and received by a
supplier. If this could be modified to include the market participant business reference number and the MPRN it
would add greatly to the ability of suppliers to track messages, in particular the registration messages. At present
you can see how many 010 messages you have sent and how many 102, 102P, 105 messages you have received
but it does not give you the information to “Link” these messages together. The market participant business
reference number would allow you to do this.
