Refining AT NEW statements

Question

I've been assigned to make some modification to an incomplete program written by another ABAPer. I have managed to fulfill most of what is required by the specification document, however, i'm having difficulty with a particular AT NEW statement that will WRITE a new PR Doc Type whenever the next line of output belongs to a different PR Doc Type than the previous line.
Currently, the PR Doc Type is always being written at each new line, no matter whether the current like is the same or different from the previous line's PR Doc Type.
Could you guys have a look what i have done so far?
NOTE: The original coding that i removed from the program were not deleted, i just * it

By the way, it's my first time trying to modify other people's codes, is there a proper way to do this. I find it more difficult to modify people's code than to write my own. Perhaps you guys could give me some advice, so i'll know what to do when i'm assigned to do it again next time?

Answer 1

Even though you think AT NEW will work on just the field that you mentioned, it is not. Your field BSART is about 6th or 7th field in your internal table. So any change in any of the field values before BSART will trigger this AT NEW BSART code.
You have to declare your own variables to keep track of the current value of BSART and previous value of the same. Also, remember that it may not have been sorted by BSART. So your logic may not work and if you change the sort, then your previous AT NEW may not work. So be sure of what you want to do there.
