Dynamically create file name in Passthrough scenario

Hi All,

I have a requirement where in a pass through file to file scenario (No mapping Involved). We have to generate the file with the following file name

Input fileName:Appcode_DDMMYYYY.xml

Output FileName:AppcodeDDMMYYYY.xml (ie. By removing "_" )

Is there a way I can get the same sender file name in the target without "_" , filename is dynamic .note that we do not have mapping for this scenario .

Any help/pointer will be of great help .
