Question about reading csv file into internal table

Some one (thanks those nice guys!) in this forum have suggested me to use FM KCD_CSV_FILE_TO_INTERN_CONVERT to read csv file into internal table. However, it can be used to read a local file only.

I would like to ask how can I read a CSV file into internal table from files in application server?

I can't simply use SPLIT as there may be comma in the content. e.g.

"abc","aaa,ab",10,"bbc"

My expected output:

abc

aaa,ab

10

bbb

Thanks again for your help.
