There r two ways -

1. Use this FM and check the Filename entered on screen with the populated table.

CALL FUNCTION 'RZL_READ_DIR'

EXPORTING

name = directory

nrlines = 1

TABLES

file_tbl = file_table

EXCEPTIONS

argument_error = 1

not_found = 2

send_error = 3

OTHERS = 4.

2. Use open Dataset

open dataset d1........

if sy-subrc <> 0.

write:/ 'File path not found'.

endif.

try this FM also.

DX_FILE_EXISTENCE_CHECK

Hi,

Use the Fucntion module FILE_GET_NAME to Retrieve Logical file path.

For example, look at the below code
