same file name in sender and receiver sftp channel

Hi Experts,

my scenario is SFTP to SFTP  and im on SAP PI 7.31

Here I am picking up the file from one location and wirting int to another SFTP LOCATION , while writing the file to Destination it should create with the same name as source file name.

I have selected ASMA in both CC and given dummy  name in receiver file name and * in sender CC . But still iam facing error as * is not understandable.

can any one tell me what should i give  file name in sender and receiver channel? and need to write any UDF?

I have gone through all the forums but still i didnt find any soultion .

Thanks,

Reddy
