FCC on sender File adapter

Hi,

We are planning to use Sender File adapter with FCC. Our target is IDOC structure  with various tree level ( more then 4 sometimes)

Would like to know if there is any limitation on Sender FCC ( as like receiver) in terms of the level it can support.

Can i take flat file with Data where first line maps to Header Sales Order ( 0.1) second & third maps to line item sales order ( 1..n) and

each line item has sales delivery ( 1.n). Convert this to IDOC on target.

Thanks
