How to populate dynamic internal table fields with data??

Hi Folks,

How to assign a particular internal table field to a dynamically assigned internal table?

I have an excel sheet, and i upload the excel sheet data into an internal IT_EXLOAD table using FM ALSM_EXCEL_TO_INTERNAL_TABLE

Now i created a dynamic internal table which has the same column as in my DB table.

I have to fill the dynamically created Internal table with the IT_EXLOAD data dynamically.

Suppose in future if i add some field in DB table and for that field if i add some column in excel sheet there is no need to change in the program.

Looking for reply...

Best Regards,

Sayak
