STRING

the payback source supply whose debt to calculate

2

Expression

Comments

If the string argument is not a valid supply, or the supply is not a payback source, this function aborts the run with an error. If the debt slot of the payback for which this supply is a source does not contain a value at the given timestep, the function evaluates to zero.
