Informatica PowerCenter COMP3 issue

        I'm working in PowerCenter Designer on a VSAM source and need to know what values in Prec and Scale should I use to get a PIC S9(9)V99 COMP-3. 

I already tried using decimal 11,2, but it didn't worked as expected, due to loaded data shows strange characters in some fields. 


Any suggestion about how I should setup this in Informatica?

Thank you! 
Best regards
