Thank you Stephen.
It works now.
I have another issue. Is it possible to have duplicate tags in the Flat file Schema?
In my case I have D02 ( Detail 02) line in the header level and the detail level. Both of them have different information.
I tried to avoid the tag for one of the D02 but it didnt work. My tag can not be more then 3 charactors since customer name start at 4th position in D02. I have other lines starting with D01 and D03 so I dont think I can use "D" or "D0" as tag. Is there any way to solve my problem?
I can not make any changes in input flat files. So I have to handle this case in schema level.
Thank you
