Handling error msg in JSPDynPage

Question

Hello,
   I am doing a replica of an SAP R3 std report in portal. I've converted the report pgm to a BAPI. My question is how to populate the BAPIRETURN table with the error messages raised from a std report? I mean how to capture these error messages? I am doing a SUBMIT to call this report from within the BAPI.
Thanks in advance.
Rgds,
Nathan.

Hi Vishal,
Please try following code :
*Code starts here
TYPES : BEGIN OF WA,
DATA(400) TYPE C,
END OF WA.
DATA : IT_FILE TYPE WA OCCURS 0,
WA1 TYPE WA.
<b>data : v_len type i.        
CONSTANTS : v_txt(4) type c value '.txt'.</b>PARAMETERS : FNAME like rlgrap-filename.
at selection-screen.
<b>v_len = strlen( fname ).
v_len = v_len - 4.
if fname+v_len(4) <> v_txt.
concatenate fname v_txt into fname.
endif.</b>
if fname is initial.
MESSAGE E000 WITH 'Enter the file path'.
stop.
ELSE.
OPEN DATASET FNAME FOR INPUT IN TEXT MODE. " ENCODING DEFAULT.
IF SY-SUBRC NE 0.
MESSAGE E000 WITH 'File does not Exist'.
stop.
ENDIF.
CLOSE DATASET FNAME.
endif.
start-of-selection.
DO.
READ DATASET FNAME INTO WA1.
IF SY-SUBRC = 0.
APPEND WA1 TO IT_FILE.
ELSE.
EXIT.
ENDIF.
ENDDO.
CLOSE DATASET FNAME.
PERFORM DISPLAY_ALV.
*******Code ends here
You can check if there is an '.txt' extension in the filename given in the selection screen. If not, concatenate  '.txt' extension else keep the filename as it is.
