It is an action by the ISO to schedule a resource for which the Participant submitted supply offers to sell energy. The ISO can schedule these resources in the Day-Ahead Market as well as commit them to provide energy in the Real-Time dispatch.
It is an action taken by a Lead Market Participant to commit or schedule a resource, to provide energy in an hour, whether or not the resource would have been scheduled or dispatched by the ISO to provide the service.
The commitment of resources in the Day-Ahead Market is one of the factors used by the ISO to dispatched resources in Real-Time. The ISO will consider start-up and shut down profiles along with the cleared Day-Ahead Market schedules and commit additional resources as required to meet capacity needs as part of the Resource Adequacy Analysis (RAA) process.
To arrive at your "Energy Real-Time " value found on your bill, for the duration period referenced on this bill, you have to sum your "Real-Time Net Energy Settlement" [found on your SR_RTCUSTSUM Real-Time Energy Market Summary Report]. The data is hourly and has to be summed for the day and then for all of the days.
Reference: WEM101 Training.
External Inadvertent is calculated by the ISO on an hourly basis at each External node and is equal to the sum of the scheduled amounts at each External Node, including any scheduled Emergency transactions, subtracted from actual amounts delivered to each Node. The calculated values across all nodes are summed and then distributed to participants based on pro rata share of the sum of all Participants Real-Time Load Obligations and Real-Time Generation Obligations over all locations, measured as absolute values per Market Rule 1, Section 3.2.1.
The Real-Time Marginal Loss Revenue is allocated on Real-Time Adjusted Load Obligation (RTALO).
The Marginal Loss credit is allocated to Market Participants pro-rata on hourly Real-Time Adjusted Load Obligation.
Real-Time Marginal Loss Revenue Allocation is the product of a Participant's pro-rata share of the pools Real-Time loss charges [Participant value divided by the Pool value] and the Real-Time Marginal Loss Revenue Value
Day - Ahead Marginal Loss Revenue = Pool Day Ahead Energy Settlement plus Pool Day Ahead Loss Revenue
Real-Time Marginal Loss Revenue Allocation = the Participant's pro-rata share of the Real-Time Adjusted Load Obligation multiplied by Pool Day Ahead Marginal Loss Revenue plus Pool Real-Time Marginal Loss Revenue

If "Contract Only" is selected, only the transaction data/contract skeleton needs to be confirmed by the counterparty, not the schedule.
