Move Excel data into an SAP internal table

By using the standard function ALSM_EXCEL_TO_INTERNAL_TABLE, you can import most Excel documents into an SAP internal table. Please note that this code is set up for spreadsheets up to 9999 rows. If you need more, use a 'DO' statement to loop through the Excel file in 9999 row segments until all is retrieved.
The code runs on 4.6B.
