sum condition

Hi LeaRupnik 

 According to the data and requirements you provided, you can not get the calculation results you want, I found several inaccuracies in the picture, you can refer to the comparison chart I provided

Here is my computed column code

NT = IF('Table'[PT]>'Table'[FT],0,'Table'[FT]-'Table'[PT])

Sum_NT = SUM('Table'[NT])
