• To clarify the problem. The initial calculation is: Round (177673.74 * 0.21,2) = 37311.49

    Then I need to make the opening of each item and the corresponding calculation, which must match the sum to the initial calculation, but it gives 0.01 difference:

    Ítems; Valores; Round (Valores*0.21,2)

    Item 1; 9,495.18; 1,993.99

    Item 2 16,455.92 3,455.74

    Item 3 23,894.20 5,017.78

    Item 4 56,454.20 11,855.38

    Item 5 71,374.24 14,988.59

    37,311.48

    But I think there is no solution can only be set in any of the items the difference
