Raised by: MRSO
Raised to address the decision taken at the MODS panel
Need to determine the most appropriate method of providing this information
XML format
May be very significant in size

Where a CoS request is rejected because there was a CoS completed in the previous twenty days the Effective date of that CoS should be provided to the requesting supplier at MPRN level

Feedback requested by January 20th
