How to dynamically get flat file csv structure?

Hi Expert,

I need to build a program to upload csv file data using Function Module 'GUI_UPLOAD'.

The issue is I have alot of csv file with different structure and different fields.

My question is how to develop a program that can dynamically get the structure (field name, length, data types) of the csv files in order to pass the data into internal table and hence write into transparent table?

Thank you.

Regards,

Honda
