BDC - Session Method - No batch input data for screen SAPMZ_TPSCREEN02 100

Question

Hi ABAP Experts,
I have written a Dialog Program For a Screen Which contains 5 fields namely,
carrid,
connid,
fldate,
price,
planetype.
I have written the PAI logic to insert whatever entries entered in the fields, into Database Table SFLIGHT.
I created a Transaction and Tested whether the entries are succesfully entetered into the Database Table and it works just fine.
Now i planned to write a BDC program for the above Transaction so that i can upload data to the Database table from a flat file.
I went to SHDB transaction and created a new recording and transferred the program to generate a source code.
include bdcrecx1.
start-of-selection.
loop at itab.
perform open_group.
perform bdc_dynpro      using 'SAPMZ_TPSCREEN02' '1000'.
perform bdc_field       using 'BDC_OKCODE'
                              '=CREA'.
perform bdc_field       using 'BDC_CURSOR'
                              'SFLIGHT-PLANETYPE'.
perform bdc_field       using 'SFLIGHT-CARRID'
                              'AA'.
perform bdc_field       using 'SFLIGHT-CONNID'
                              '0017'.
perform bdc_field       using 'SFLIGHT-FLDATE'
                              '11/01/2007'.
perform bdc_field       using 'SFLIGHT-PRICE'
                              '767'.
perform bdc_field       using 'SFLIGHT-PLANETYPE'
                              'A310-200F'.
perform bdc_transaction using 'Z_TPSCREEN02'.
perform close_group.
Then i defined an internal table which contains the same fields as those in my Screen and Transaction.
I populated the internal table from a flat file using GUI_UPLOAD function module.
I want to clarify - I got this flat file by using the GUI_DOWNLOAD module and later i uploaded the same file using GUI_UPLOAD.
I tested whether the internal table is populated or not using LOOP  AT ITAB. WRITE Statements.
Its working just fine.
Finally my code look like this.
report ZVMREC
       no standard page heading line-size 255.
TABLES: sflight.
DATA: BEGIN OF itab OCCURS 0,
carrid LIKE sflight-carrid,
connid LIKE sflight-connid,
fldate LIKE sflight-fldate,
price TYPE sflight-price,
planetype TYPE sflight-planetype,
      END OF itab.
CALL FUNCTION 'GUI_UPLOAD'
  EXPORTING
    filename                      = 'C:\users\vamc\documents\flightinfo.txt'
    FILETYPE                      = 'ASC'
    HAS_FIELD_SEPARATOR           = 'X'
  tables
    data_tab                      = itab.
include bdcrecx1.
start-of-selection.
loop at itab.
perform open_group.
perform bdc_dynpro      using 'SAPMZ_TPSCREEN02' '1000'.
perform bdc_field       using 'BDC_OKCODE'
                              '=CREA'.
perform bdc_field       using 'BDC_CURSOR'
                              'SFLIGHT-PLANETYPE'.
perform bdc_field       using 'SFLIGHT-CARRID'
                              'AA'.
perform bdc_field       using 'SFLIGHT-CONNID'
                              '0017'.
perform bdc_field       using 'SFLIGHT-FLDATE'
                              '11/01/2007'.
perform bdc_field       using 'SFLIGHT-PRICE'
                              '767'.
perform bdc_field       using 'SFLIGHT-PLANETYPE'
                              'A310-200F'.
perform bdc_transaction using 'Z_TPSCREEN02'.
perform close_group.
endloop.
I checked for errors, activated and executed.
I gave session name and executed, it generated same number of sessions as number of records.
I went to SM35 and Processed one of the sessions in foreground.
It brought my screen up with all fields fill up by the fields of first record in the internal table and with
OK Code popping up.
I check the OK Code.
Now the problem has come up, its says
*No batch input data for screen SAPMZ_TPSCREEN02 1000 *
My session was now incorrectly processed,
Please help me to fix this problem.
I searched so many forums and google it a lot.
But i didn't find any clue.
Kindly take your time and have a look at this problem and let me know how can i fix it.
Thank you very much all.

Answer 1

I used this code to convert the date format. I'm still getting the short dump.
   DATA: v_yyyy(4) TYPE c,
       v_mm(2) TYPE c,
       v_dd(2) TYPE c,
       v_date(8) TYPE c.
v_yyyy = itab-fldate(4).
v_mm = itab-fldate+4(2).
v_dd = itab-fldate+6(2).
concatenate v_yyyy v_mm v_dd  into v_date. 
I'm once again, putting my code.
report ZVMREC
       no standard page heading line-size 255.
TABLES: sflight.
DATA: BEGIN OF itab OCCURS 0,
carrid LIKE sflight-carrid,
connid LIKE sflight-connid,
fldate LIKE sflight-fldate,
price TYPE sflight-price,
planetype TYPE sflight-planetype,
      END OF itab.
CALL FUNCTION 'GUI_UPLOAD'
  EXPORTING
    filename                      = 'C:\users\vamc\documents\flightinfo.txt'
    FILETYPE                      = 'ASC'
    HAS_FIELD_SEPARATOR           = 'X'
  tables
    data_tab                      = itab.
include bdcrecx1.
start-of-selection.
loop at itab.
DATA: v_yyyy(4) TYPE c,
       v_mm(2) TYPE c,
       v_dd(2) TYPE c,
       v_date(8) TYPE c.
v_yyyy = itab-fldate(4).
v_mm = itab-fldate+4(2).
v_dd = itab-fldate+6(2).
concatenate v_yyyy v_mm v_dd  into v_date.
perform open_group.
perform bdc_dynpro      using 'SAPMZ_TPSCREEN02' '1000'.
perform bdc_field       using 'BDC_OKCODE'
                              '=CREA'.
perform bdc_field       using 'BDC_CURSOR'
                              'SFLIGHT-PLANETYPE'.
perform bdc_field       using 'SFLIGHT-CARRID'
                               ITAB-CARRID.
perform bdc_field       using 'SFLIGHT-CONNID'
                               ITAB-CONNID.
perform bdc_field       using 'SFLIGHT-FLDATE'
                              V_DATE.
perform bdc_field       using 'SFLIGHT-PRICE'
                               ITAB-PRICE.
perform bdc_field       using 'SFLIGHT-PLANETYPE'
                              ITAB-PLANETYPE.
perform bdc_transaction using 'Z_TPSCREEN02'.
perform close_group.
endloop.
Kindly take a look at it and please help me out. I tried very hard. But i dont understand why?
Thanks
Shiv
