how can we change occurances?

while declaring our datatypes, how can we change the occurances.

the issue is..

while i am converting my file, say CSV its working fine. But it creates a unique record for each and every record.

Can I get some clues in building a single file even after conversion ? I gues its the problem from occurances. If any other, can u please let me know ASAP

Thanks in advance
