[PBI_Chris67]

Hello,

I am new on the forum and would be very gratefull if some of you could tell me how to do something as simple a the calculation of a % of achievement between two columns from a single database.

So far, I just create a first column calcuating the difference between Column A & Column B, et's call it Call it Column C

And than I created another column with Column C / by Colonne A but the result is not accurate...

Thanks for your help !

There is a chance you could be getting negative values which would definately cause some issues

try this:

Column C = Column A - Column B (like you already have)

New Percentage column = ABS(Column C) / Column A

then format this new column to be a percentage

If column B was larger than column A the number would be negative so ABS() gets the absolute value (ignores negatives) so that result in Column C will always be the difference between A and B

Can you post some sample data and what you expect as a result?
