Variant Program - REFVAL01

Hi

I am able to execute a rate that I have designed permissible at Facts level

It has two variant Programs LUMSUM01 and REFVAL01

in the installation Facts I could maintain the Operand value for The operand created using Category Ref Value

There are two fields : ENTRY VALUE and VALUE to be Billed

May I know what actually these fields are meant for ?

are they referring to the Demand in KW to be billed

of Course in billing Calculation I have used KWH and TPRICE and Value is calculated

But I want to know exactly what these fields indicate ?

Thanks in Advance
