Re: Bex Formula

Question

Hi All,
I need to create a formula in bex designer.
This is the calculation:
% (A/B - 1)
Say A = 500, B = 100
(500/100 - 1) * 100 = 400 %.
One condition is that, i need to check both the kyefigure
has value.
Incase if B has zero, how to handle it.
what is NDIV0(x) and NOERR(x)? explain pls.
Regards,
Anand.

Answer 1

Hi,
Lets take an example. Let
A=500
B=100
C=NDIV0(A/B)*100.
So C=500
Also D= C OR 0.
Remember OR operator would always return 0 or 1.
If any one of the operands is true... the value returned is 1, only if both the operands are false is the return value 0.
Now Since C=500 hence the value D holds is 500 OR 0 which would return 1.
Now D = 1
Hence the final formula is
CD - 100D that is
500 * 1 - 100 * 1 = 400.
Which is what we needed...
Now lets take another example
A = 500
B = 0
Hence C=NDIV0 (500/0) which would return 0.
Hence C=0
Hence D = 0 OR 0. return value here would be 0 (since both the operands are false).
Hence D = 0.
Now the final formula would be =
C * D - 100 * D which after substitution would turn as
0 * 0 - 100 * 0 which would again be 0.
this is what we needed...
right ?
Let me know...
