Revert to SOLR” MPD 4 covers SPU but not Grouped Unmetered. The SOLR process in Supply
depends on receiving MM 105 to trigger the CoS Gain workflow. As there is no such message
associated with Grouped Unmetered, because it is a manual process, then GMPRN gains due to
invoking the SOLR process would have to be handled manually.
Therefore the process as defined in MPD 29 – Change of Supplier -Grouped Unmetered should be
followed for Reversion of Group Unmetered site to the Supplier of last Resort.
