2	Distributor sends confirmation of request for grid usage registration to new supplier	(Outbound message) UtilitiesGridUsageRequestERPCreateConfirmation_Out (Inbound message) UUtilitiesGridUsageRequestERPCreateConfirmation_In	c d
3	New supplier sends request for grid usage termination to old supplier	(Outbound message) UtilitiesGridUsageRequestERPCreateRequest_Out (Inbound message) UtilitiesGridUsageRequestERPCreateRequest_In Note The system uses the same service operations as in step 1 for the registration and termination.

Using Enterprise Services for Reversal

You can also use services to reverse individual steps of the grid usage process. The system uses the pattern Request - Confirmation, which means that a confirmation follows the reversal request.

Supplier sends request (outbound message) for reversal of grid usage process to distributor: UtilitiesGridUsageRequestERPCancellationRequest_Out.
Distributor or supplier receives request (inbound message) for reversal of grid usage process: UtilitiesGridUsageRequestERPCancellationRequest_In
Distributor sends confirmation (outbound message) of reversal request to supplier: UtilitiesGridUsageRequestERPCancellationConfirmation_Out.
Supplier receives confirmation (outbound message) of reversal reqeust: UtilitiesGridUsageRequestERPCancellationConfirmation_In.
