XML to EDI Conversion Configurations

Hi All,

I have done a scenario File to File scenario ( XML to EDI ) Conversion.

In  Receiver File adapter I have provided X12Converter Module to convert XML to EDI and it is successful .

But I need clarification on below points:-

1. Is EDI Separator Adapter is  required for the scenario similar like EDI to XML scenario?

2. How can I send Functional Ack. ( 997) in this case?.

Please guide ...

Regards,

Tibin
