Hi,

It will work for all kind of files.

After that use FM ALSM_EXCEL_TO_INTERNAL_TABLE instead of GUI_UPLOAD.

Reward all useful answers.

Hello

Assuming that you have stored your data as <i>.csv </i>file you can use the following coding:

CALL METHOD cl_gui_frontend_services=>gui_upload " for uploading the file

The itab for the data upload should be unstructured (line type = string or C-container).

Next you convert the unstructured data into your BDC data using function module <b>TEXT_CONVERT_CSV_TO_SAP</b>.

Regards

Uwe
