Question Regarding Dataset

How to transfer trailing spaces to a file in datasets? I am using SAP 7.0 and unable to output trailing spaces to a file instead it truncates in transfer dataset.

I want to output as below after '000000001A' I should output 3 spaces basically at end of the record which I am unable to figure how to pass spaces at the end of record.

"3020060504155309 000000000001 000000001A "

Any of your experience will help.

Regards,

Ramesh
