If I filter by month my formula works fine but if i sort by SaleRep or Product the result of the formula went wrong.
In fact the formula is the value of the whole sales of the product in the period selected divided by the sales for aream, salesrep or brickcode, depending on the level where i'm looking in the pivot table.
What i need to achive is to keep the result that i have without filter on the dimension also if i filter for one rep or one product.
