Maintaining Requirements Parameters 
To simplify maintenance of the demand program, you can preset requirements parameters for the Create indep.reqmts, Change indep.reqmts and Display indep.reqmts functions, and for the evaluation of Demand Management.

Define the requirements parameters for the history in the same way for all functions.
