How to call different viewer according its filetype?

[Former Member]

Hi guys,

there is a requirement. We write a custom report which shows all the attachments of a project. and the ALV report needs the drill down function too.

So the question is that how it can determine its viewer in pc according its file extension, such DOC calls MSdoc,PDF calls Adobe Reader?

Thanks very much!!

[athavanraja]

how are you opening the file? when the user clicks (drill down) what exactly you are doing?

Hi Raja,

Thanks.

Do you remember the last my question? In last question, I said I was writting a custom report show the projects and its attachment in the ALV.

So now requirement is that when user click the attachment title, the program should show it. If it's a PDF, call PDF reader. etc.

Currently I call the function 'SO_DOCUMENT_VIEW_MANAGER'.

Notice: INSTID_B you can refer the FM"BDS_GOS_CONNECTIONS_GET" as you told me:)

-Begin of Code--

---

LS_DOC-FOLTP = WA_DATA-INSTID_B+0(3).

LS_DOC-FOLYR = WA_DATA-INSTID_B+3(2).

LS_DOC-FOLNO = WA_DATA-INSTID_B+5(12).

LS_DOC-OBJTP = WA_DATA-INSTID_B+17(3).

LS_DOC-OBJYR = WA_DATA-INSTID_B+20(2).

LS_DOC-OBJNO = WA_DATA-INSTID_B+22(12).

LS_DOC-FILE_EXT = WA_DATA-EXT.

CALL FUNCTION 'SO_DOCUMENT_VIEW_MANAGER'

EXPORTING

DOCUMENT = LS_DOC

• FOLMEM_DATA = folmem_data

• HEADER_DATA = header_data

• RECEIVE_DATA = receive_data

FUNCTION = 'DISP'

• SELECTIONS =

OWNER = SY-UNAME

• IMPORTING

• DOCUMENT = LS_DOC

• FOLMEM_DATA = folmem_data

• HEADER_DATA = header_data

• RECEIVE_DATA = receive_data

• FOLMEM_DATA =

• HEADER_DATA =

• RECEIVE_DATA =

• NEXT_FUNCTION =

EXCEPTIONS

FUNCTION_NOT_AVAILABLE = 1

OTHERS = 2

.

IF SY-SUBRC <> 0.

MESSAGE 'Can''t the documents!' TYPE 'E'.

ENDIF.

end of code----

yes. It can call Excel or Adobe Reader. But both the Application said they can't open the file ( saying the file is corrupted, etc)

Hope someone can give some suggestions

[Former Member]

In fact, I have test the class CL_GOS_SERVICE. IF there is one project A, and it has three attachments( one is Notes, another is PDF, the other is XLS). The class can show the three attachments onetime. But it's not what I need. What I need in in the following senario:

there are now records show in the ALV grid.

project-name attachment-title attachment-icon

A notes notex-icon (in the program i set it as ICON_RTF)

A PDF-XXXX PDF-icon (this attachment is PDF)

A XLS-XXXX XLS-icon (XLS file)

When the user double-click the 'attachment-title' ,such as PDF-XXXX , I want to the program can directly call Adobe Reader to open the file.

BTW: 'SO_DOCUMENT_VIEW_MANAGER' can call the Adobe reader, but it said the file is broken.

Thanks!
