Connection for Excel file

Hi everyone,

I am new to ABAP and i have some questions to ask.

Here is the situation.

My client want SAP data to update automatically from excel file from another computer daily.

1. I know somehow we can get data from excel to internal table and to sap table.

2. I can use SM36 to do the background process, so i can run the update daily.

Here is my real question:

1.  i use FM ALSM_EXCEL_TO_INTERNAL_TABLE to get the data, but the ROW and Column are difficult to adjust. Is there any other ways i can get the        data to internal table and to SAP table?

2. How can i connect sap to another computer to take the excel file? is it possible?
