Try this

Index on Str(99999999999.99 + pp_Amount, 15, 2) + Str (pp_NumOper, 6) Tag Amount1

>Hi All,

>How can I create an index expression (in the case below tag Amount1) involving two numeric values (pp_NumOper and pp_Amount) when one of them (pp_Amount) can assume negative values, getting the proper sorting sequence (i.e. from the smallest value to the biggest value, considering their algebraic values and not their absolute values).
