Locking header row of CSV

Hi Folks,

I want to lock/restrict Header row of Data Export CSV,so that once a user download the file,he shouldn't be able to edit it.

1) Header Row non-editable:-

--Infotable (Datashape) is defined

--Data Export button event downloads corresponding infotable's CSV file

      ---> Now,user should start inserting/modifying values starting from 2nd row only.

2) Default values in 1st Row of downloaded CSV file.

--Once the User downloads a CSV file, he should get default values in the 1st row(after Header row).

Is it possible anyway?

please revert if anyone has ever tried this or I shall raise a ticket at PTC support?

Thanks,

Tarun
