Thanks for the response.
With processing of flat file documents from TN,I am able to do it.
I wanted to ask how we further process in the main service which we call in the processing rule of TN.
In case of XML file sent from TN ,there is an inbuit service called bizdocToRecord.By using this service we can convert get the values in the Record/Document format as required by us.
Are there any buit in service for flat file which works exactly the built in service bizdocToRecord .
If not,then can you let me know how to go ahead with processing of flat files from TN.
