Encountering error in simple file 2 file scenario

Question

Hi,
Working on a very simple file 2 file scenario , where input contains 1 header record identified with a key field and detail record conntains more than 1 records identified with key field. Used very specific FCC. But it was unable to generate the output file (a simple text file without any translation) giving errors as below -
1. File Adapter Receiver Channel cc_target: Not initialized - cannot proceed: null
2. MP: exception caught with cause com.sap.engine.interfaces.messaging.api.exception.MessagingException: Channel has not been correctly initialized and cannot process messages
3. Adapter Framework caught exception: Channel has not been correctly initialized and cannot process messages
4. Delivering the message to the application using connection File_http://sap.com/xi/XI/System failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: Channel has not been correctly initialized and cannot process messages.
Input File structure is like
H1,XXXXX
D1,YYYYYY
D1,ZZZZZ
D1,NNNN
H1 and D1 are key identifiers of header and detail record
Need same format output file, used FCCs (1) fieldSeperator (2) endSeparator (3)ignoreRecordsetname (4) fieldNames (5) keyfieldvalue.
Can anyone pls suggest ?

Hi ,
Use FCC Like this.
Doccument Name                        MT_Source( Your Source Message Type name)
Doccument Namespace                   http://xxxxxx(Your Message type Name space)
Recordset Structure                   Header,1,Detail,*
Key Field Name                        field1
Key Field Type                        String
Header.fieldSeparator            ','
Header.fieldNames                field1,field2
Header.keyFieldValue             'H1'
Header.endSeparator              'nl'
Detail.fieldSeparator            ','
Detail.fieldNames                field1,field2
Detail.keyFieldValue             'D1'
Detail.ignoreRecordsetname        true
Detail.endSeparator              'nl'
Let me know if you are getting any problem.
