Hi,
Can you give other samples?
What do you mean by add or subtract KF1? Add all the KF1 and subtract all the KF1 when AB and AC, respectively?
I mean,there is no problem in the addition,but in the subtraction part how will you know which number is the MINUEND in your example? For example the 4th line has a value of KF1 = 20 so the result will be -10?
MINUEND - SUBTRAHEND = DIFFERENCE
