One perform with different internal table structure to 1 function module

former_member181966 — Fri, 21 Apr 2006 20:44:06 GMT

HI all,

I am downloading an internal table in to excel using function EXCEL_OLE_STANDARD_DAT'”

Here’s my code ..

PERFORM sub_excel_download2..

form sub_excel_download2

FM ::: call function 'MS_EXCEL_OLE_STANDARD_DAT'

exporting

file_name = 'C:\TEMP\file'

CREATE_PIVOT = 0
DATA_SHEET_NAME = ' '
PIVOT_SHEET_NAME = ' '
PASSWORD = ' '
PASSWORD_OPTION = 0

tables

PIVOT_FIELD_TAB =

data_tab = it_excel_tab2

file_not_exist = 1

filename_expected = 2

communication_error = 3

ole_object_method_error = 4

ole_object_property_error = 5

invalid_filename = 6

invalid_pivot_fields = 7

download_problem = 8

others = 9.

if sy-subrc <> 0.

write: / 'Error downloading to Excel'.

endif.

endform.

I have 3 internal tables which I want to download , but user has to select check box on selection screen . Remember my internal tables structures are different .

Q: Is there any way I can pass internal table dynamically to my perform as well as to call function 'MS_EXCEL_OLE_STANDARD_DAT' on the basis of user selection, using one perform ?

I want something like

Perform excel_download using dynamic table . ( where my excel table structures are different )

Form excel_download using dynamic table .

call function 'MS_EXCEL_OLE_STANDARD_DAT'

exporting

file_name = 'C:\TEMP\file'

CREATE_PIVOT = 0
DATA_SHEET_NAME = ' '
PIVOT_SHEET_NAME = ' '
PASSWORD = ' '
PASSWORD_OPTION = 0

tables

PIVOT_FIELD_TAB =

data_tab = dynamic_table

file_not_exist = 1

filename_expected = 2

communication_error = 3

ole_object_method_error = 4

ole_object_property_error = 5

invalid_filename = 6

invalid_pivot_fields = 7

download_problem = 8

others = 9.

if sy-subrc <> 0.

write: / 'Error downloading to Excel'.

endif.

Endform

Waiting for your input/suggestion.

Thanks

May be I am missing something but did you try

"Form excel_download tables dynamic_table"?

You can do this by using Field symbols.

Define

field-symbols <FS> type any table.

and assign you structure to <FS> and pass <FS> to the FM.

Sri,

I want a Dynamic internal table in Perform .

True, you have your dynamic internal table defined, filled and then this form is called. So I see it like this.

fill itab1.

perform download_table_to_excel tables itab1.

fill itab2.

perform download_table_to_excel tables itab2.

fill itab3.

perform download_table_to_excel tables itab3.

form download_table_to_excel tables itab.

call function ....

endform.

Isn't this your flow?

Do you mean that the name of the table should be dynamically determined or that the structure of the table itself is dynamic (or both)?

NO Sri, I have already 3 internal tables Itab1, itab2, itab3 .. which has different structures OK ..

Now I don’t want to write perform 3 times as well as I don’t want to call FM 3 times .

I am looking for that I write perform in which I pass internal table ( Itab1,itab2,itab3 ) dynamically as well as pass the IT structure to FM dynamically .

In this way my One perform can out put Itab,itab2 and itab3 when user select the different check box.

I hope I make my self clear .

Thanks

You don't have to specify the type of the tables parameter in your FORM definition.

Ok I think I understand it now. So you have one perform within which you want to dynamically download different itabs based on the checkboxes user selected.


  FORM download_itabs_to_excel.

    FIELD-SYMBOLS: <itab> TYPE STANDARD TABLE.

    IF p_chkbx1 = 'X'.
      ASSIGN itab1[] TO <itab>.
      CALL FUNCTION 'MS_EXCEL_OLE_STANDARD_DAT'
        EXPORTING
          file_name                       = p_file
*   CREATE_PIVOT                    = 0
*   DATA_SHEET_NAME                 = ' '
*   PIVOT_SHEET_NAME                = ' '
*   PASSWORD                        = ' '
*   PASSWORD_OPTION                 = 0
       TABLES
*   PIVOT_FIELD_TAB                 =
         data_tab                        = <itab>
*   FIELDNAMES                      =
* EXCEPTIONS
*   FILE_NOT_EXIST                  = 1
*   FILENAME_EXPECTED               = 2
*   COMMUNICATION_ERROR             = 3
*   OLE_OBJECT_METHOD_ERROR         = 4
*   OLE_OBJECT_PROPERTY_ERROR       = 5
*   INVALID_PIVOT_FIELDS            = 6
*   DOWNLOAD_PROBLEM                = 7
*   OTHERS                          = 8
                .
      IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
      ENDIF.
    ENDIF.

  ENDFORM.                    "download_to_excel

You have to repeat the IF P_CHKBX1 = 'X' for each of the checkboxes selected.

Hope I got it correct this time.

Yes you understand the one part of story. Now like you are passing internal table to FM in the above code.

Can I also pass internal table to

PERFORM download_itabs_to_excel using <dynamic table >?.

FORM download_itabs_to_excel using <dynamic_table>?.

Thanks a lot for your input and time ..

Let us say we can do this, what do you want to do with the <dynamic_table> inside the form? Just pass it to the function call? In that case you can put the function call in a form and don't use any parameters. Just make the previous field-symbol definition global. So now the flow more or less will be


form download_based_on_user_choice.

  if p_chkbx1 = 'X'.
    assign itab1[] to <itab>.
    perform download_itab_to_excel.
  endif.

  if p_chkbx2 = 'X'.
    assign itab2[] to <itab>.
    perform download_itab_to_excel.
   endif.

  if p_chkbx3 = 'X'.
    assign itab3[] to <itab>.
    perform download_itab_to_excel.
  endif.

endform.

form download_itab_to_excel.

  call function .... table ... = <itab> ...

endform.

If this what you want?

No:( . never mind !!!!

Let say

itab1 "Filled with data for excel

itab2 :filld with data for excel

itab3 : filled with data for excel .

I only want only one perform

I do this ... and Its working :)

if p_chkbx1 = 'X'.

assign itab1[] to <itab>.

elseif p_chkbx2 = 'X'.

assign itab2[] to <itab>.

elseif p_chkbx3 = 'X'.

assign itab3[] to <itab>.

endif.

*"Where out tab could be 1,2, or 3 on user slection

perform download_excel using <Itab>.

form download_excel using Itab

CALL FUNCTION 'MS_EXCEL_OLE_STANDARD_DAT'

EXPORTING

file_name = p_file

CREATE_PIVOT = 0
DATA_SHEET_NAME = ' '
PIVOT_SHEET_NAME = ' '
PASSWORD = ' '
PASSWORD_OPTION = 0

TABLES

PIVOT_FIELD_TAB =

data_tab = <itab> "Could be 1,2, or 3

FILE_NOT_EXIST = 1
FILENAME_EXPECTED = 2
COMMUNICATION_ERROR = 3
OLE_OBJECT_METHOD_ERROR = 4
OLE_OBJECT_PROPERTY_ERROR = 5
INVALID_PIVOT_FIELDS = 6
DOWNLOAD_PROBLEM = 7
OTHERS = 8

IF sy-subrc <> 0.

You didn't mention that they are radiobuttons. I thought they are real checkboxes where the user can choose all or some or none of the options. Yes if they are just radiobuttons, then you can do the way you explained. I see that you figured it out already.
