Recordsset per message spliting failed

Question

Hi All,
My scenario is File to File.
1) Sender file conists of 50 records
2) Receiver end it should contain 2 files with 25 records each.
My source and receiver structures are  maintained as
Source Structure : 
   Record-------> 1...1
         Data----
>1...1
receiver Structure:
  Record----
>1..1
           Header----->1..1
           Data----
>1..unbounded
           Trailer----
>1..1
Sender Comm Channel FCC parametes: 
Qos                                         : Exactly Once
Recordset  Name                 : Record
Recordset structure              : Data,*
Recordssets per Message : 25
Data.fieldNames                   : field names,......
Data.fielsSeparator               : |
Data.endSeparator                : 'nl'
Receiver Comm Channel FCC parametes: 
Recordset Structure : Header,Data,Trailer
Header.fieldNames                   : field names,......
Header.fielsSeparator               : |
Header.endSeparator                : 'nl'
Data.fieldNames                        : field names,......
Data.fielsSeparator                    : |
Data.endSeparator                     : 'nl'
Trailer.fieldNames                    : field names,......
Trailer.fielsSeparator               : |
Trailer.endSeparator                : 'nl'
My requirement in receiver end 2 files should be of with 25 records only
Header
25 records
Trailer
But i am getting only one file with 50 records
Header
50 records
Trailer.
In MONI i am able to see only one successful message .
Can any body tell me were i did wrong.
Thanks

Sai,
you cannot achive this for data. PI can split records based on Recordset and not  for a particular structure of a recordset.
you have to define  the strcuture "Data"  as RecordSet and then only PI can split the records.
Since u have 3 structures ( Header, Data and Trailer) ... u cannot utilize this "Recordset Per Message" feature. You could have if you have only one structure.
For this u can use a simple multimapping. In message mapping just make the target message type unbounded
Write a small  UDF and then count the records and then put a context change after 25 records.
U will get 2 files in the receiver.
