HI Zuben,
To acheive this
calculates A - (IF B Not Empty then take B or else take C.)
Z = A - if (B != " '', B, C)
A = Key Figure
B = Key Figure
C = Key Figure
Try this !!!!!!!
If u create a  CKF,u will have operators in it,in that choose Boolean Operators,again in that chose
1)is not equal to
and
2)Equal to.
for ur calculations.
Z= Calculated Key Figure.
Z= A - (B NE 0)B + ( B EQ 0)C
Case One -- B NE 0
Z= A-(1 * B)+0
Z = A-B
Case Two -- B EQ 0
Z= A-(0 * B)+(1*C)
Z = A-C
I guess this is your requirement.
