How to read only the first record of CSV file in PI?

Hi experts,

My requirement is need to read only the first line or record of incoming CSV file in SAP PI 7.1

Note:  first record should be header in CSV file. (It means i need to read only the header record only from the incoming CSV file)

How I can achive this?

Is it possible to achive this by using FCC or UDF?

Please revert your suggestions and solutions for this ASAP.

Thanks,
