Recordset per message at sender file channel

Hi,

I have a requirement where I need to process the huge volume messages. So I decided to choose split the records through Recordset per message option in sender file adapter.

But my source structure have Header,1,Detail,*,Footer,1

And my target structure have Detail,* without Header and Footer.

How do I config the sender channel and let me know whether recorset per message will support even in nested structure also?

Because when I test with dummy scenario structure like Detail,* for both sender and receiver, Recorset per message is working.

I have declared the channel like below.

Recordset Structure: DETAIL,1

Recordset per messsage: 1

If I use the structure like Header,1,Detail,*,Footer,1 it's not working.

Please help me to setup the configuration to split the messages.

Regards

Arun
