Upload Excel to an SAP table control and show the result in Excel

Call up JavaScript functions that use the "Excel.Application" object to read and write table cells while executing an InputScript.

In the InputScript we can either press "Enter" in SAP for each row entered, or first fill in all rows available on the screen and then press enter for a block of new rows.
If performance is not really critical we suggest that you choose the "row by row" approach, since this allows you to return any row-related error message to Excel and have it assigned to the right Excel row. Also, the scrolling becomes more complex when you use blocks of rows.

In transaction MF42N we add an "Upload" button which allows the user to upload an Excel file into the SAP table. If any error occurs we skip the erroneous row and save the SAP error message in the Excel file. If no error occurs we set a status "OK" into the Excel row.

If the InputScript is run again for the same file we omit all rows with status "OK".

In the transaction MF42N it is a bit difficult to continue after erroneous inputs. If you can correct the errors, that's not a problem, but the InputScript doesn't know how to correct an error and must let the newly made entries be canceled before the next rows (if any) are entered. We solve this problem by pressing F12 (Cancel) in the SAP transaction after each error, which clears the new rows, but allows us to continue in the transaction by selecting "No" in the cancellation warning popup.
