Hi SoHelpMeCodd,

Thank you for your help, its working for me,

i have one more problem in Header of the output file,

when i open output file in excel the header is displaying as expected HDR but the date and time are displayed within quotes "YYYYMMDD" , "HHMMSS"

actual out put from csv should be

HDR YYYYMMDD HHMMSS

and when it is opened within notepad++ it should be

"HDR", "YYYYMMDD", "HHMMSS"

is there any setting that i need to configure in properties of DFT, i am using expression in DFT properties to get header.

Thanks in advance
