Getting the error 'Cannot interpret data in file' while uopoading.

Hi All,

Iam getting the error "Cannot interpret the data in file' while uploading the data from legacy system to sap using the function module 'GUI_UPLOAD'.

I have used the following parameters in the FM.

FILENAME = P_PATH1

FILETYPE = 'ASC'

DATA_TAB = I_TAB1.

Any body please suggest the solution.

Regards,

Narasimha
