Problem Statement
Due to the high volume and timing of Registration messages being sent by the CSS, some messages are at risk of being received by REC Parties and Service Providers out of sequence. When messages have been received out of sequence, there is a risk that the information maintained in MPRS, including Registration Status, will be incorrect and will not match that held in the Registration Service. This in turn means MPRS updates to Parties could be triggered in error.
Proposed solution summary
- As a Consumer I want the Switch process to work effectively so that I can switch Electricity Supplier without delay or issues As a Consumer I want the Switch process to work effectively so that if my Switch needs to be cancelled it is done so without delay or issues
- As an Energy Supplier I want the Switch systems and process to operate effectively so that appointment Market Messages will be sent to my agents at the appropriate time so that there is no disruption to the Consumer switching experience
- As the ERDS Provider I only want to receive the first Pending message and then the Secured Active confirmation message, in order that there is no risk of processing CSS messages out of sequence which could impact a timely Switch for electricity Consumers As the CSS Provider I want the messages I send to MPRS to be processed effectively so that there is no disruption to the Switch process and Consumers’ Switches can be confirmed or cancelled as required
