Posting Value ZERO in BADI in BPC10.0

Hello Experts,

I have developed a badi at UJ_CUSTOM_LOGIC, in this I have a input template through which I am posting some Rates and using these rates I have to arrive at some Final value based on the calculation. BADI is doing the calculation.

But when I am making my rate a zero in that case after calculation nothing is getting posted

Rate Calculation Posted value

4000 1*4000 4000

-4000 1*-4000 -8000

0 1*0 Nothing is posted.

Now how do I address this. Mathematically, if I try reversing the original amount it will post the double amount with reverse sign....

How do I address this?

Regards

Rohan
