Problem in Simple file to file scenario

Hello,

I am new to SAP PI 7.3. I am doing a simple file to file scenario. The source file contains key,name,id,gender,role & location field. I have done a simple mapping to create the same file in the target side. I have done all the configuration in ESR & ID.

But the problem is that in the target file ( Destination File ) i am getting only key field and the other fields are missing.

Note: In communication channel monitoring, the communication channel is functioning properly and in message monitor also, the status is 'delivered'.

The source payload also contains all the fields correctly. In message mapping (in ESR) also, the target payload is also generating correctly. But in the destination file I am getting the key field only and the rest fields are missing.

Can you please suggest me what to do and where is the problem?

Thanks & Regards,

Moumita
