Sensitivity Analysis. Data tables provide a shortcut for generating multiple views for a model in a single operation as well as a way to view and compare the results of all of the variations together on a single worksheet. For each decision variable, the report shows its coefficient in the objective function, and the amount by which this coefficient could be increased or decreased without changing the dual value. So, to perform this we first need to create the basic assumptions on Excel and then set the Payment method. For each trial value in the data cell, Solver is called on to re-solve the problem.
