Reg: Logic for context change

Question

Dear friends,
I have a scnario where i need to  uploade the sumary of financial entries.
For every one line item i need to create a target side as 2 line item for debit and credit entry.
I achived this by using  duplicatesubtree.
Now the issue is  for all the entries there should only one debit entry by summing all the line item amout and all the credit item entries.
Even this is achived by using the context change at the sum function.
In fico we can uploade only 900 line item not more that. for this i have make use of counter and udf to resolve this.
But now for context change i need to genarate one debit entry for every 899 credit entrries(input line items).
It mean for 899 input item sum to be taken in to one debit line item at target in the duplicatesubtree
For this i have a udf it gives a counter change after 899 line items.
Now on this change how should i change the context..for sum and create the debit item after every 899.
I have refered this thread .
[context change  in message mapping]

Hi Vijay,
To get Sum
Source item (0 .. outbound)
           line1 (0..1)
           line2 (0..1)
           line3 (0..1)
           line4 (0..1)
           line5 (0..1)
           line6 (0..1)
Now map Line6 --> (RemoveContext) u will get all values ===> Write UDF1 ===> Map to first element under Item1
===> Write UDF2 ===> Map to first element under Item1
UDF1
public void CreditSum(String[] a,ResultList result,Container container){
float count = a.length;
float c = count/2;
int d = (int)c;
int sum=0;
String Sum_str = " ";
for(int i=0;i<=d-1;i++)
sum = sum+Integer.parseInt(a<i>);
Sum_str =Integer.toString(sum);
result.addValue(Sum_str);
UDF2
public void Credit2Sum(String[] a,ResultList result,Container container){
   //write your code here
    //write your code here
float count = a.length;
float c = count/2;
int d = (int)c;
int sum=0;
String Sum_str = " ";
for(int i=d;i<=count-1;i++)
sum = sum+Integer.parseInt(a<i>);
Sum_str =Integer.toString(sum);
result.addValue(Sum_str);
Thx
