Hello Expert,
I want to enhance the user exit USEREXIT_SOURCE_DETERMINATION, which is used in VA01.
Since my logic is a little bit complext, I maybe have to write 1,000~2,000 code lines. Fortunately, I find Some of the code lines can be reused. So I want to encapsulate these lines in one subroutine and call it in different places. This should be able to decrease the code lines greatly.
But, unfortunately, I can't find where I can write the subroutine. Can any expert tell me where to write my subroutines in the case?
Thanks in advance,
Best Regards, Johnny.
