how to Create header, detail and trailer record in a file using talend

[Anonymous]

Hi,
I have N no of records in a table and write it into a positional file which has the following format:
Header record layout
-------------------------
currentdate 1-6
Detail record layout
------------------------
ename 1-10
esal 11-18
trailer layout
-----------------
Totalsal 1-10
sample output file
--------------------
2011-24-05
ganesh 0001000
shong 0002000
00003000
So my output file is, one header entry, one trailer entry and multiple detail entries.

Hi
You need to write the header, trailer and details entries into the same file one by one with the feature 'append source file'.

Hi
The job looks like:
extract the header data from a data source or use the tFixedFlowInput to define the header data --main-->tFileOutputPositional_1

onsubjobok
|
extract the Detail data from a data source or use the tFixedFlowInput to define the header data--main---tFileOutputPositional_2(write the records into the same file and check the option 'Append')
|

extract the trailer data from a data source or use the tFixedFlowInput to define the header data--main---tFileOutputPositional_3(write the records into the same file and check the option 'Append')

Thanks for your valuable suggestions. I need a output file which has the following format:
Main Header (1st line)
Batch Header(2nd Line)
Record1 (3rd line)
Record 2 (4th line)
.
.
.
Record N (n+4th line)
Batch Trailer(n+5th line)
Batch Header(n+6th line)
Record1 ((n+7th line)
Record 2 (n+8th line)
.
.
.
Record N
Batch Trailer
FileTrailer(last line)
Main Header - contains the current date
Batch header - sequence number ( 1 for Header 1)
record - amount (fetch from db)
Batch trailer - (Batch Amount Total)
File Trailer - (File Amount Total)
N - no of records in a batch
Ex:
---
23/11/2011
1 (Batch No)
12 (record1)
8 (record2)
20 (Batch1 Amount Total)
2(Batch No)
30 (record3)
20 (record4)
50 (Batch2 Amount Total)
70 (File Amount overall Total)
Please reply ASAP. Thanks in advance.

Hi
I have replied you and give an example job in previous post, have you tried to create the job? Do you understand the 'append' option?
