Real time idoc to file scenario - URGENT!

Question

Hi all,
I have a real time idoc to file scenario with the idoc structure as below:
WP_PLU03
   IDOC
     Begin
     EDI_DC40
     E1WPA01
        E1WPA02
Now as can be seen, EDI_DC40 is the header record common for the eniter idoc. But the segment E1WPA01 will repeat for each item sent from R/3. E1WPA01 in turn has many segments within it whcih corresponds to that one item.
Now the problem i am facing is, I did the mapping for all required fields from E1WPA01 to my file structure and it works fine if i send one 1 instance of E1WPA01. But when i send multiple instance of E1WPA01 for each item, my result in teh file should be 1 line of record for each E1WPA01. But this doesnt happen. It takes allE1WPA01 as 1 and gives only one record in the file.
How can this be overcome? this is a very common requirments? did i miss anything in the configuration?
Thnaks,
Yash

Hi Matias,
I have two instances (may be much more than 2) of the same segment in the idoc (E1WPA01) and each instance should create a new root in the target message structure as in the link below

I have mapped the segment E1WPA01 with the root like this:

Hence it creates 1 root for each segment. But for complex mappings such as:

the 2 input parameter to the UDF - KONDART and KONDWERT - the queue can be seen. the problem which i m facing here is in this queue, values from both the instnace of the segment E1WPA01 is taken together where each instance should be processed seperately. The first 4 values in the top queue(till VKP0) belongs to the filed KONDART of the 1st isntance of the segment and the 1st 4 values of the below queue (till 17) belongs to the field KONDWERT. Similarly the remaining belogns to the other segment. My logic in UDF is built taking only one instance at a time. Is there anyway i can distinguish between the two instance within my UDF?
I hope u understand my problem here.
Thanks,
Yash
