Question about exceptions in function module GUI_DOWNLOAD

To all,
I add the function module 'GUI_DOWNLOAD' in the ABAP report program. After the user download the data to excel, the program also displays a report on the screen for print output.
If the user keep the excel file open and tries to replace the file on download, the program gives an error message 'Access to file denied' and the program ends without displaying a report on the screen.
Is there any way not to end the program even if download is failed?
I would like the program displays a report after it gives an error message.
So I am trying to use exceptions. But if I code to give messages, the programs ends as above. And if I just make exit when it happens, no error message and the program displays a report but the user don't know if the excel file was updated or not.
Could anybody kindly let me know how to code exceptions and messages if it is possible the program works I hope.
Thank you very much in advance.
Best regards,
Miki Komatsu

　I figured out how to do that.
Thanks.
Best regards,
Miki

Function Module GUI_DOWNLOAD: Type String Issue

I am working in 4.6C. I have used this Function Module many times in the past without issue, but not at this site. It abends and gives me the error message:
The call to the function module "GUI_DOWNLOAD" is incorrect:
The function module interface allows you to specify only fields
of a particular type under "FILENAME". The field "FNAME" specified here
has a different field type.
Here is the field declaration in the code:
PARAMETER: fname type rlgrap-filename DEFAULT 'C:/New_PO_Format.xls'.
The import parameter in GUI_DOWNLOAD for FILENAME is type STRING. When I double click on STRING in the FM I get "Unable to find a tool to process request". And, TYPE STRING does not exist in the system? I started making a Z version of GUI_DOWNLOAD, but it started giving me headaches because I had to start copying other SAP function modules.
Am I missing something? Or, is there a new and improved version of GUI_DOWNLOAD to use?

data : v_file type string.
PARAMETER: fname type rlgrap-filename DEFAULT 'C:/New_PO_Format.xls'.
start-of-selection.
v_file = fname.
use v_file in gui_download parameter.
Thanks

advance thanks,
Warm regards,

Hi,
if that condition is not satisfied,and u didn't handle that exception while calling function module then in the runtime error u will get the text as the description of the exception in function module definition.

How to write the exceptions in function module

dear all,
how to write the exceptions in function modules with example.
thanq
jyothi

Hi,
Raising Exceptions
There are two ABAP statements for raising exceptions. They can only be used in function modules:
RAISE except.
und
MESSAGE.....RAISING except.
The effect of these statements depends on whether the calling program handles the exception or not. The calling program handles an exception If the name of the except exception or OTHERS is specified after the EXCEPTION option of the CALL FUNCTION statement.
If the calling program does not handle the exception
· The RAISEstatement terminates the program and switches to debugging mode.
· The MESSAGE..... RAISING statement displays the specified message. Processing is continued in relation to the message type.
If the calling program handles the exception, both statements return control to the program. No values are transferred. The MESSAGE..... RAISING statement does not display a message. Instead, it fills the system fields sy-msgid, sy-msgty, sy-msgno , and SY-MSGV1 to SY-MSGV4.
Source Code of READ_SPFLI_INTO_TABLE
The entire source code of READ_SPFLI_INTO_TABLE looks like this:
FUNCTION read_spfli_into_table.
""Local Interface:
*" IMPORTING
*" VALUE(ID) LIKE SPFLI-CARRID DEFAULT 'LH '
*" EXPORTING
*" VALUE(ITAB) TYPE SPFLI_TAB
*" EXCEPTIONS
*" NOT_FOUND
SELECT * FROM spfli INTO TABLE itab WHERE carrid = id.
IF sy-subrc NE 0.
MESSAGE e007(at) RAISING not_found.
ENDIF.
ENDFUNCTION.
The function module reads all of the data from the database table SPFLI where the key field CARRID is equal to the import parameter ID and places the entries that it finds into the internal table spfli_tab. If it cannot find any entries, the exception NOT_FOUND is triggered with MESSAGE ... RAISING. Otherwise, the table is passed to the caller as an exporting parameter.
Calling READ_SPFLI_INTO_TABLE
The following program calls the function module READ_SPFLI_INTO_TABLE:
REPORT demo_mod_tech_fb_read_spfli.
PARAMETERS carrier TYPE s_carr_id.
DATA: jtab TYPE spfli_tab,
wa LIKE LINE OF jtab.
CALL FUNCTION 'READ_SPFLI_INTO_TABLE'
EXPORTING
id = carrier
IMPORTING
itab = jtab
EXCEPTIONS
not_found = 1
OTHERS = 2.
CASE sy-subrc.
WHEN 1.
MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno.
WHEN 2.
MESSAGE e702(at).
ENDCASE.
LOOP AT jtab INTO wa.
WRITE: / wa-carrid, wa-connid, wa-cityfrom, wa-cityto.
ENDLOOP.
The actual parameters carrier and jtab have the same data types as their corresponding interface parameters in the function module. The exception NOT_FOUND is handled in the program. It displays the same message that the function module would have displayed had it handled the error.
Or
just have to decide what exceptions u want and under what conditions.
then declarethese exeptions under the exceptions tab.
in the source code of ur function module.
if
like this u can code .
now when u call the function module in tme mainprogram.
if some error occurs and u have declared a exception for this then it will set sy-subrc = value u give inthe call of this fm.
in the fm u can program these sy-subrc values and trigger the code for ur exception.
Please reward if useful

Some question about the renegotiation function in SRM Contract (GOA)

Hi All Expert,
We are on SRM 5/4.6, there is a question about the renegotiation function in SRM GOA.
Can we renegotiate the price for some parts in the GOA items with this function ( e.g. Only renegotiate one item in the contract) ?
Will the item price updated automatically after the renegotiation?
Many thanks in advance!!!

Hi Sanjeev,
Many thanks for your help.
One more question, if I add a new item when we renegotiation, will it be transfered to contract and create a new item after that?
Thanks and best regards

Questions about user-defined functions

Hello all,
I've got some questions about user-defined function in a message mapping:
1) How can I get the current date/time in format yyyy-mm-dd hh:mm:ss ? What is the java code for this?
2) I want to use the StreamTransformation constant TIME_SENT, only this is not in the right time-zone.
It is GMT and it should be CET (1 hour difference). How can I convert this in Java?
Can somebody help me with this?
Thanks in advance.
Kind regards,
Marco van Iersel

Hi Marco,
If the date format is fixed as you have mentioned,please use this:
                                String test = "2009-03-27 23:15:30";
          String test1 = test.substring(11,13);
          if(!test1.equals("23"))
          int a = Integer.parseInt(test1);
          int b = a+1;
          System.out.println("b"+b);
          String c = Integer.toString(b);
                                test = test.substring(0,10)+" " + c + test.substring(13,19);
                                return test;
          if(test1.equals("23"))
          test = test.substring(0,10)+ " 00" + test.substring(13,19);
          return test;
                                else return "";
Kindly let me know if this works.
Thanks.

Exceptions in function module

Hi,
What are the exceptions in function module.
Thanks in advance

HI,
Exceptions are used to return the error which happens in function module to the calling program.
You can't show error messages directly from Function modules. So when there are some error occurs in function module it raises the desired exception. and this exception number is passed back to calling program. in this way calling program can trace out the error happens in function module.
REgards,

What is the Exceptions in function module

Hi,
wt is the exceptions in function module? can anyone tell me?
Thanks
swathi

Exception is the mechanism by which you can give the error messages back to the program.
Say for the REUSE_ALV_GRID_DISPLAY, we have so many exceptions. Every exception has some meaning. Say the exception PROGRAM_NOT_FOUND will be raised when you had passed wrong program name in the CALLBACK program.
PROGRAM_NOT_FOUND = 1...
If the exception was raised than this value will be set to the SY-SUBRC.
SO, by accessing SY-SUBRC, you can get to know which exception was raised.

Help! Question on calling a function module

Hi,everybody.
I have a problem about function module. I created a normal function module which would call itself when user double clicked some screen elements. But when I exit the function called in second time, the value of the global variants in function called in first time changed to the value in function called in second time. It seems that they shared the global variants. So is there any ease approach to recover the data to the original value?
Thanks for any help!

Hi Dan,
you can use field-symbols instead.
check the following code
IM_TEST is the importing parameter
EX_TEST is the exporting parameter
FUNCTION ZTEST_RECURSION.
*"*"Local interface:
*" IMPORTING
*"     REFERENCE(IM_TEST) TYPE C
*" EXPORTING
*"     REFERENCE(EX_TEST) TYPE C
field-symbols : <var> type c.
if im_test = 1.
assign im_test to <var>.
*<var> = 4.
elseif im_test = 3.
assign im_test to <var>.
endif.
if im_test = 1.
CALL FUNCTION 'ZTEST_RECURSION'
EXPORTING
    IM_TEST       = '3'
endif.
ex_test = <var>.
ENDFUNCTION.
i hope this will help you.

Question about PL/SQL Function in report

Hi all. I have a (basic) question about using a PL/SQL function in a report. In my report page I have an item (PL/SQL function) that has the following syntax:
return username from t1
where username like 'Le%'
I reference this item in an email process. Ideally this function would return all usernames that begin with 'Le' in the drafted email; however, its not looping so I'm only getting a return on the first name.
I have a few books on PL/SQL but I'm not exactly sure where to start - I imagine there is a loop process I need to integrate into the function but, like I said, I'm not sure.
I would have posted this to the PL/SQL forum but also wanted some feedback on whether or not using this method is the best way forward. Essentially I have a table with usernames and just want to send email messages based on some simple logic.
Thanks!
Len

Hi Sergio,
First, it's an honor to have you reply to my post. Thanks!
To be more specific,
T1 is a table containing the results from a user security scan. Username is a column in this table containing user names. What I have done is create a page in HTML DB with the following elements:
1. An 'Item' containing the PL/SQL function that is hidden. The purpose of this Item is to generate information from T1 that meets the simple logic parameters - in this case, the user names that begin with "Le". I have called this Item P145_TT
2. A 'Process' containing references to HTMLDB_MAIL. The 'Process' looks similar to this:
HTMLDB_MAIL.SEND(
P_TO => '[email protected]',
P_FROM => 'Anon Email Account',
P_BODY => 'Note: This message was automatically generated. Do not attempt to reply to this email.
These are the users that begin with Le: '||:P145_TT||' ',
P_SUBJ => 'Summary');
3. A 'Button' to submit the process and (hopefully) send the message containing all users that adhere to the logic in the function.
4. If I use 'return username from t1...' I will get a username generated, but like I said previously, it only gives me the first and does not loop.

Raise exception in function module call from SAP owned program

I need to raise an exception in a function module to terminate a transaction, display a error message and return to to previous selection screen so the user can fix the error before moving forward.......
How do you do this when the program using the function module is SAP owned?
Thank You!
Jeff

Hi,
After calling the function module, you can do something like this.
IF SY-SUBRC <> 0.
RAISE EXCEPTION.
ENDIF.
