Each row is one published transaction. This action is the obligation recorded on that transaction — a change amount, as USAspending publishes it. Running total is computed by Glassbox VA as the cumulative sum of those amounts up to and including the row, so the last running total equals the award's net obligations shown above. The cumulative-total columns in the source files are not used: they are not frozen per modification.
