the problem is that no data is read. Like if sy-index 1 or 2 or 3 .... is a nothing is accepted, because nothing is read. inothing. In no time through the loop will read anything.

OPEN DATASET FOR INPUT IN TEXT MODE file_server ENCODING DEFAULT sy-subrc = 0 , the file is open, why is not a single record read?

For open dataset

sy-subrc Description

0 File was opened.

8 Operating system could not open file.

For read dataset

sy-subrc Meaning

0 Data was read without reaching end of file.

4 Data was read and the end of the file was reached or there was an attempt to read after the end of the file.

Data: platzhalter(50000) type c.

Aytec, please format your code as IF sy-subrc &lt;&gt; 0 doesn't display &lt;&gt;!

Now sy-subrc = 4 is not an error when you use READ DATASET, it just indicates the end of file, so just don't display the message:

IF sy-subrc &lt;&gt; 0. MESSAGE i007(zerror). EXIT. ENDIF.

Note that your code is buggy as sy-subrc may be changed by GET_LONGTEXT method. So you should place the code above right after the READ DATASET.

data:wf_string type string.
data:  lf_ref TYPE REF TO cx_root.
DO.
TRY. 
READ DATASET file_server INTO platzhalter.
*Catch system exceptions
    CATCH cx_root INTO lf_ref.                           "#EC CATCH_ALL
      wf_string = lf_ref->get_text( ).
      IF wf_string IS NOT INITIAL.
        MESSAGE s904(zf) WITH wf_string DISPLAY LIKE 'E'.
      ENDIF.
ENDTRY.

if sy-subrc ne 0.
      IF sy-index EQ 1. "No data in the file
      EXIT.
 ELSE. "End of File
        CLOSE DATASET file_server.
        EXIT.
      ENDIF.
endif.

though sy-subrc is set to 4, something may have been read (sy-subrc = 4 just indicates the end of file has been reached). Check in debug whether the variable contains something or not.
