Calculated Field giving wrong value in Totals in Pivot Table

jindalsteel Unfortunately, that's how regular pivot tables perform. The calculated field is applied to the row level. When in a row with an SNO then it looks if the sum for that SNO is >= 500 and gives the correct result. When in the Total row it look is the Total is >= 500. And it is, so it gives you the Total but not the sum of the SNO's >= 500.

You need to move into Power Pivot and DAX measures to resolve such 'problems'. The attached file contains a basic solution in Power Pivot. If you have never worked with PP or DAX, that's going to be a challenge, as it isn't the most user friendly formula 'language'. But Google is your friend and will lead you to many sources to start learning about it.
