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
