Problem with pop-up screens in BDC

Question

I have recorded a transaction in SHDB.
when i run the recording from SHDB, it is running fine,...but after I transfer the recording to a program or function module and then run it, the second screen which is a pop up screen is not getting displayed.
wat can be done?

Answer 1

Dear Balaji,
OK, I  encountered this before. There are two scenarios here:
1. The screen pop up. (Because this is the first time you get into the transaction for this login session.).
2. The screen will not pop up. (Because this might be the second time or after,  you get into the transaction.)
In the second case, because the parameter ID (or what ever SAP's memory is holding) got the value after the fist time entry through the pop up, so it wouldnt pop up again.  You have to select it from the menu and enter it if you want to change the value. I believe there is a place for you to change the value.
So, now, come to your BDC. Your BDC records could only handle one of the case.
To cater for both cases, I did a Dummy BDC (which did nothing on the transaction, using the RED Cancel ( 'BDC_OKCODE' '/EEESC'.)button.), fill in everything required, then press cancel button.
Then only, do your actual processing. This time, remember to fill in your value of the pop up window through the menu button to invoke the pop up.
Bellow is my dummy BDC:
*&      Form  f_dummy_first
      This routine will execute CJ88 without doing anything.
      The purpose is to eliminate the popup window to enter
      controling area. The controlling area will be enter through
      the button on the manu.
-->  p1        text
<--  p2        text
form f_dummy_first.
  PERFORM dynpro USING :
        'X'    'SAPLSPO4'         '0300',
        ' '       'BDC_CURSOR'    'SVALD-VALUE(01)',
        ' '       'BDC_OKCODE'    '=FURT',
        ' '    'SVALD-VALUE(01)'  'MY01',
        'X'     'SAPLKO71'         '1000',
        ' '     'BDC_CURSOR'    'LKO74-BZDAT',
        ' '     'LKO74-PERIO'    p_fispd,
        ' '     'LKO74-BUPERIO'  p_fispd,
        ' '     'LKO74-GJAHR'    p_fisyr,
        ' '     'LKO74-BZDAT'    p_budat,
        ' '     'LKO74-VAART'    '1',
        ' '     'LKO74-TESTLAUF'  ' ',
        ' '     'BDC_SUBSCR'      
                'SAPLKAOP                                0550BLOCK1',
        ' '     'LKP74-POSID'     ' ',
        ' '     'BDC_OKCODE'         '/EEESC'.
  CALL TRANSACTION c_cj88
             USING  bdc_tab MODE 'N' UPDATE 'S'.
  clear bdc_tab. refresh bdc_tab .
endform.                    " f_dummy_first
Please suggest if there is any other better solutions.
Good luck....
