BDC Unable to populate the field for transaction code LT04

[srikanthnalluri]

All,

I have created a BDC for the transaction code LT04, in that for the field 'Foreground/Background' i have passed 'H' (Foreground) in the recording. Through i am populating 'H'(Foreground) it does take the 'System_Guided' as input while processing. BDC is not taking the populated value. Any suggestion to populate the value.

Thanks in advance.

    bdc_dynpro( exporting iv_program = 'SAPML03T'
                          iv_dynpro  = '0131'
                changing  ct_bdcdata = lt_bdcdata ).
    bdc_field( exporting iv_fnam    = 'LTAK-LGNUM'
                         iv_fval    = '240'
               changing  ct_bdcdata = lt_bdcdata ).
    clear lv_fval.
    lv_fval = lv_tbnum.
    bdc_field( exporting iv_fnam    = 'LTBK-TBNUM'
                         iv_fval    = lv_fval
               changing  ct_bdcdata = lt_bdcdata ).
    bdc_field( exporting iv_fnam    = '*LTBP-TBPOS'
                         iv_fval    = space
               changing  ct_bdcdata = lt_bdcdata ).

    constants: foreground type lvs_dunkl value 'H'. 
    clear lv_fval.
    lv_fval = foreground.
    bdc_field( exporting iv_fnam    = 'RL03T-DUNKL'
                         iv_fval    = lv_fval           "<--Passing 'H'
               changing  ct_bdcdata = lt_bdcdata ).

Hello S Nalluri,

Not sure if there is a Mode called 'H', below are the possible modes:

• A = Foreground (Step by step processing will be done by you)

• N = Background (All the Processing will be done in Background)

• E = Display Error ( If there is any error, it will be displayed in log otherwise it is similar to background mode)

Also the datatype for the variable should be type C.

Regards!

H is the value from this screen:

Thanks Veselina Peykova Now i understand the issue.

Use transaction SHDB to record the batch input & generates the corresponding program, that will help you to solve a lot of errors

I tried with SHDB recording but same result frdric.girod

Hi,

Are you appending internal table lt_bdcdata with field name 'BDC_CURSOR' , field value 'RL03T-DUNKL' .

Hello S Nalluri,

Probably once you are populating the value to lv_fval there may be some space before the actual value, try debugging and understand if the value H is actually passed to lv_fval. if there is any space before H then as per the domain values space corresponds to System Guided thats the reason you get the issue.

Before passing the value try to condense the variable lv_fval as shown below, this should solve the issue. Let us know for any clarification needed.

CONDENSE lv_fval.

I tried it already but for some wired reason it is not working @Satish Kumar Balasubramanian

You should run your batch input in dialog and with CALL TRANSACTION .. MODE 'A' (display all screens) so that to understand what really happens...

[srikanthnalluri]

sandra.rossi I checked it in MODE - A, it just didn't populate the value. I am not sure what else i should try i have tried all the suggestions already.

I requested to change the config to default the LT04 mode as 'Foreground' but this option is also ruled out.

[Sandra_Rossi]

S Nalluri What kind of field is it, a dropdown listbox? Can you post a screenshot?

[srikanthnalluri]

sandra.rossi It is a drop down field. Please find the screen shot.lt04-field-dunkl-field-issue.png

[Sandra_Rossi]

S Nalluri In dropdown listbox, you must enter the code, not the text. You may display the codes in the listbox via the SAP GUI settings > interaction > visualization 1 > checkbox display codes in listbox.

Oops Veselina Peykova has already explained the possible values:

• D for background
• H for foreground
• space for system-guided

I don't understand why you have an issue then...

[Sandra_Rossi]

NO ISSUE.

data(lt_bdcdata) = value bdcdata_tab(
    ( program = 'SAPML03T' dynpro = '0131' dynbegin = 'X' )
        ( fnam = 'LTAK-LGNUM'  fval = '240' )
        ( fnam = 'LTBK-TBNUM'  fval = '1' )
        ( fnam = '*LTBP-TBPOS' fval = ' ' )
        ( fnam = 'RL03T-DUNKL' fval = 'H' ) ).
call transaction 'LT04' using lt_bdcdata mode 'E'.

Could not find any particular reason for this issue, ended up writing two separate BDCs and handled the issue.

Thanks all for your suggestions.
