Validation of outbound FIle with respect to outbound Message type

Hi Experts,

I have file system at outbound side and defined the Data Type, Message Type for this. Now a want to validate the outbound file against the Message type structure i have defined. Now if the file is not validated against Message type, i want to create the log file that will explain what were the errors in the outbound file and move the file to other archive else send it to inbound system.

Plz suggest the solution.

Thanks and regards,

Vishal
