Problem in Calling transactions from a program

former_member506713 — Wed, 20 May 2009 07:06:59 GMT

Hi Experts,

I have a requirement to process 3 transactions F-29, VA01 and F-32 in a program 1 after another.

So i tried like this.

call TRANSACTION 'F-29'.

call TRANSACTION 'VA01'.

call TRANSACTION 'F-32'.

This is working and posting also done correctly.

But problem is whenever i am clicking back button at any screen of program it should go to initial screen, i.e, F-29 initial screen.

But in my case if i m pressing back button while i am in F-29 screen, its going to VA01 initial screen and if back button is pressed in VA01, its going to F-32 screen.

Is there any possibilities to capture 'BACK' in Sy-UCOMM?

Please Suggest

Thanks in Advance

Lucky

Hi,

CASE sy-ucomm

when 'BACK'

Call the transaction 'F-29'.

ENDCASE.

Hope this will help.

Thanks Pinaki and thanks everybody.

I tried as per your suggestion.

But after pressing back button, its coming back to Z program but sy-ucomm contains nothing. I checked it by debugging that its finding nothing in sy-ucomm and going to next transaction.

Hi,

As because SY-UCOMM is initial , in case statement WHEN ' ' is checked.

Please check once please -

CALL TRANSACTION 'F-29'.
CASE sy-ucomm.
  WHEN space.
    CALL TRANSACTION 'F-29'.
ENDCASE.
CALL TRANSACTION 'VA01'.
CASE sy-ucomm.
  WHEN space.
    CALL TRANSACTION 'F-29'.
ENDCASE.

run the below code and check


DATA:   MESSTAB LIKE BDCMSGCOLL OCCURS 0 WITH HEADER LINE.
DATA:   BDCDATA LIKE BDCDATA    OCCURS 0 WITH HEADER LINE.

call TRANSACTION 'F-29' USING BDCDATA
                     MESSAGES INTO MESSTAB.
if not messtab[] is initial.
  refresh messtab.
  call TRANSACTION 'VA01' USING BDCDATA
                     MESSAGES INTO MESSTAB.
  if not messtab[] is initial.
    refresh messtab.
    call TRANSACTION 'F-32' USING BDCDATA
                     MESSAGES INTO MESSTAB.
  endif.
endif.

Hi All.

Back option is working fine. Thanks all for ur valuable suggestions.

can anybody tell how can i capture the values entered in the screen?

**********************************************************************

I tried using 'DYNP_VALUES_READ' FM like below.

DATA:

l_i_dynpfields TYPE STANDARD TABLE OF dynpread INITIAL SIZE 0,

l_wa_dynpfields TYPE dynpread,

l_carrid TYPE RF05A-NEWKO.

*Populate the Parameter Name whoso value is required

l_wa_dynpfields-fieldname = 'RF05A-NEWKO'. "Customer Account

APPEND l_wa_dynpfields TO l_i_dynpfields.

*Call the FM to read that value

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

dyname = 'SAPMF05A'

dynumb = '111'

TRANSLATE_TO_UPPER = ' '
REQUEST = ' '
PERFORM_CONVERSION_EXITS = ' '
PERFORM_INPUT_CONVERSION = ' '
DETERMINE_LOOP_INDEX = ' '

TABLES

dynpfields = l_i_dynpfields

EXCEPTIONS

invalid_abapworkarea = 1

invalid_dynprofield = 2

invalid_dynproname = 3

invalid_dynpronummer = 4

invalid_request = 5

no_fielddescription = 6

invalid_parameter = 7

undefind_error = 8

double_conversion = 9

stepl_not_found = 10

OTHERS = 11

IF sy-subrc = 0.

*Get the value

READ TABLE l_i_dynpfields INTO l_wa_dynpfields

WITH KEY fieldname = 'RF05A-NEWKO'.

IF sy-subrc = 0.

l_carrid = l_wa_dynpfields-fieldvalue.

ENDIF.

**************************************************

and also FM 'GET_DYNP_VALUE' as

*DATA : l_newko TYPE string.

*CALL FUNCTION 'GET_DYNP_VALUE'

*EXPORTING

*I_FIELD = 'RF05A-NEWKO'

*I_REPID = 'SAPMF05A'

*I_DYNNR = '111'

*CHANGING

*O_VALUE = l_newko.

****************************************************

But both are not able to collect values.

This is required so that account no of customer i can be used directly in 1st screen of transaction 'F-32'.

Thanks

Lucky

I don't know how to read items from screen, but of course you can get customer open items from BSIK table.

Got the solution finally taking directly from table BSEG considering posting document number.
