Call function RFC in a loop and kill old session

Hi,
we have a problem with a program.
here's a part of the code:
DO.
    CALL FUNCTION 'YC_REFRESH_GPT_START_CM25' STARTING NEW TASK 'TEST'
      EXPORTING
        i_profile       = p_prfl
        i_werks         = p_werks
        i_arbpl_low     = s_arbpl-low
        i_arbpl_high    = s_arbpl-high
      TABLES
        t_arbpl = it_arbpl.
    PERFORM wait_for_refresh.
    PERFORM terminate_session.
ENDDO.
So the program does a call function, waits a while, then terminates the session and recalls the function.
Apparently, like this the data should be updated.
But in the terminate session, the session is terminated using:
CALL 'ThUsrInfo' ID 'OPCODE' FIELD opcode_delete_mode
                   ID 'MODE'    FIELD l_mode.
And it works the first time, but the second time there is a dump.
So, is there another way to achieve what this program is trying to do?
Or is there another way to kill the session?
Thanks!!

Hi,
the DLL will stay in memory as long as there is a program running which has not closed (unloaded) the DLL.
Doing repetitive calls to the DLL is irrelevant in this context. LV opens the DLL as soon as needed and will only unload it when there is no VI in memory which has a CLN to that DLL...

Call function module in backgrouns task and in update task

Hi Gurus,Pls crear me on the " <b>Call function module in backgrouns task and in update task</b>".
how it works and waht is the link with LUW releated to these .
also heard that commit work statement aslo linked with this.
Pls clarfiy me with expalnation of code.

Hi sridhar,
the explanation already given is correct and good. Small add-on:
All functions called during one LUW with addition IN UPDATE TASK are stored together with their actual parameters in a temporary memory area. The moment a COMMIT WORK is issued, the functions are released to be executed by a so-called update task which is running in the background. This explains why functions called in update task never return anything, no SY-SUBRC and no export or table parameters If a function called in update task raises an exception or runs into an error the calling user will get an express message informing about this. Also, all database updates done by this update process are rolled back to keep consistency.
This proceeding helps to keep database tables consistent and allows the user to keep on doing his work before all database updates are complete. You may have seen messages like "material will be changed" after saving. If you open the same material immediately, you'll get a message "object locked by...<yourself>". This means the update task is still running.

Computer name in R3 when call function RFC from CRM to R3

Hi all,
i nead the computer name in R3 when I come to R3 from CRM .
In R3 i call function 'TERMINAL_ID_GET' in R3   but I don't retrieve the computer name.
i tried also to call function 'TERMINAL_ID_GET' in destination 'CRM'   but I don't retrieve the computer name.
The code in R3:
CALL FUNCTION 'TERMINAL_ID_GET' DESTINATION 'R3GETCRM'
      EXPORTING
        username             = sy-uname
      IMPORTING
        terminal             = l_terminal_usr41
      EXCEPTIONS
        multiple_terminal_id = 1
        no_terminal_found    = 2
        OTHERS               = 3.
This function works ok when i call her direct from R3 or direct from CRM,
but not give me in R3 the computer name when i came to R3 From CRM.
Thanks for your cooperation.
dany

thats because 'TERMINAL_ID_GET' is not a RFC (check the attributes tab of the FM from SE37)
if you dont find a RFC to do t his you can wrap this FM with a custom RFC and use it.
if you want all the logged on users info (computer name and other info) then you can use THUSRINFO FM which a RFC

Call Function - RFC

We are in the process of provding interface while creating production order. We would like to check certain paramters and receive some paramters from our legacy system ( Oracle 8i based). I have gone through help file and understand that RFC API can help. But the problem is I am not familiar with C or C++. Can I develop same type of process <u>in VB</u> i.e. sending parameters to legacy and receive from legacy at the time of saving Production Order .

Closing and Killing Portal Session Error

Hi Experts,
I'm getting some problems with my killing sessions. We did some implements with Integrated Planning and repots are running in the portal. I have noticed a dramatic low performance in my portal and I realized that sessions are not closing in the portal. I've been trying log our from the portal session and the session still alive (I seem them in SM04 transaction). How Could it be possible if I'm logging out properly?..... Is there something I've been missing???? What else Could I do for fixing the problem???
Thanks for your help (Any help would be rewarded).
David

Hi,
As far as understand you are running reports from an ABAP backend system in the portal and the sessions in the ABAP backend system are not closed by the portal.
Which technology are the reports based on (BSP, transaction) ?
It seems to me the Distributed session management(DSM) in the portal is not working and therefore not triggering the closing of the sessions in the backend when the user logs off or navigates to another page.
(it might also be that the BSP is defined as stateful )
See http://help.sap.com/saphelp_nw04/helpdata/en/ca/a9a7408f031414e10000000a1550b0/frameset.htm for more info on DSM

How to return out of a subVI into a calling VI and not stop the calling function

I am writing a program that consists of a calling VI and a sub VI. I want the calling function to be running continuously and be able to trigger the sub VI (via voice activation). I want the sub VI to time out automatically after 10 seconds and return to the calling (master) VI, which will continue running until the sub VI is called again.
I found a way to time out the sub VI using the "stop" command, but this quits the calling VI too, which cannot happen. I know there is no "return" or "soft stop" in LabVIEW, but does anyone know a way to do this?
Solved!
Go to Solution.

I am a student working on a project involving voice activation. the overall idea is to have a person say a command (like go or something) that then gives them a 10 second window to say other commands and have them recognized by the program. The idea is to eliminate false positives by nesissitating a calling command that is not spoken very often, and then having 10 seconds to activate what we are trying to vocally control. I hope that helps clarify the intent of the program.
I was using a flat structure just because I sucessfully got the sub VI to time out using a flat structure with a boolean false on one side with a wait of 10 seconds, then a boolean true on the other that triggered a stop. this successfully ran the sub VI for 10 seconds and then stopped it; however, it also stopped the calling VI which is my problem. right now, I have a while loop in the calling VI that contains an elapsed time timer and the sub VI and it works (kind of). it sucessfullly calls the sub VI, but not for any given amount of time. it changes each time it runs; sometimes it stays running for 10 seconds before returning to the calling VI, sometimes it just flashes, and sometimes it just doesn't return. I am also experimenting with mathscript code.
My partners and I are all new to labVIEW, so if something seems less than optimal, it is because of our inexperience.
Thanks again for your help.

ABAP Dump when calling Function Module Starting New Task

Hi all. I have a tricky situation now, I am doing a POC on parallel processing.
I am getting an ABAP dump on the following Call Function line which is in class lcl_steer_114numc (See below for full program):
METHOD start.
    CALL FUNCTION 'Z_ZZCLS_STEER_114NUMC'
      STARTING NEW TASK me->id
      CALLING me->finish ON END OF TASK.
ENDMETHOD.                    "start
However I get the following ABAP dump:
Short text
    Statement "CALL FUNCTION .. DESTINATION/STARTING NEW TASK/IN BACKGROUND TASK"
The function module only contains a wait statement to simulate parallel processing. It is strange that it dumps here, because when I change the FM call to another call that has been triggered successfully from other classes, it still produces the same ABAP dump.
The background of the Proof Of Concept is to see if I can get an event to trigger the next process that depends on the outcome of the previous process. Parallel processes are run in the start methods by calling RFC.

Well, the thing is I did manage to run 3 other Function Modules asynchronously succeesfully prior to that function call, with the same exact function call syntax. Further more, I have tried editing it with your suggestion but I get the exact same dump.
The complete function group can be downloaded here (slinkee file):

First call function problem

hello there,
i am using labview's first call function inside a for loop, inside a sequence structure. inside the for loop the function works fine activating a true/false structure, however, when i attempt to do the same thing outside the for loop i get a broken arrow. It says that the the tunnel of the case structure, to which i have wired the first call function, is missing an assignment to it. Cant understand why it is fine in one part and not in the other. Perhaps somebody has encountered this before? I have atttached the relevant code
Thank you
Dave

Stranger, I think if you will look closely at the case statement you will see that you have inadvertently added an output tunnel. Either delete the case and redo it or just click on the input tunnel and move it down enough to see and delete the unwired output tunnel.

GuiXT call function

Hi, how can i use call function in guiXT with import and export parameter?
please give me some pointers..
thanks!

no need to answer.. not possible for me since im not using the licensed GuiXt.. =)

Trouble calling function

I am having trouble calling simple functions and/or procedures for my database. First of all, here is the DDL to create a single table with a single entry:
CREATE TABLE Security (SSN char(9) NOT NULL, PASSWORD char(10) NOT NULL);
INSERT INTO Security ('123456789', 'mypass');
Now, I want to create a function that takes an SSN and password and returns true if they are associated, and false otherwise. I was able to successfully create the function with no errors using the following:
CREATE OR REPLACE FUNCTION CheckPassword(inSSN VARCHAR2, inPASS VARCHAR2)
RETURN BOOLEAN
IS
valid_pass BOOLEAN;
selected_pass char(10);
BEGIN
SELECT password INTO selected_pass FROM security WHERE ssn=inSSN;
RETURN selected_pass = inPASS;
END CheckPassword;
show errors
However, now I cannot call the function. I have been looking online and the references say to use "call" or "execute", and I have tried both with no luck.
When I try to use "call CheckPassword ('123456789', 'mypass');"
call CheckPassword ('123456789', 'mypass')
ERROR at line 1:
ORA-06576: not a valid function or procedure name
When I try to use "execute CheckPassword ('123456789', 'mypass');"
BEGIN CheckPassword ('123456789', 'mypass'); END;
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00221: 'CHECKPASSWORD' is not a procedure or is undefined
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
It keeps saying undefined or not a valid function or procedure, but it is. I've created it and can see that it is exists and is valid by using "select * from user_objects". I have also tried "call function CheckPassword..." and "execute function CheckPassword..." but neither work. What am I doing wrong?
Thanks
Blake

You've created a function which returns a boolean type. You can't just ignore the return value of a function.
Oh, and another thing...the table you created uses CHAR types, but your function uses VARCHAR2. This can lead to some bugs.
Are you sure you need CHAR types in your table?

Populate SELECT-OPTIONS default value using CALL FUNCTION

Hi Experts,
I would like to populate SELECT-OPTIONS s_currm default with value in w_currm, however, it doesn't seem to work. Can you please advise what the correct syntax is.
Note that CALL FUNCTION 'GET_CURRENT_YEAR' is working correctly and populating w_currm (as I can use it in a SQL SELECT statement), however, it does not seem to work for SELECT-OPTIONS s_currm.
Thank you for your time.
Code snippet is as a follows:
REPORT Z_DOWNLOAD_BSIS_TEST.
*Data Declaration
DATA: w_currm TYPE BSIS-MONAT.
*Define current fiscal month
CALL FUNCTION 'GET_CURRENT_YEAR'
EXPORTING
    BUKRS         = 'X999'     " Company Code
    DATE          = SY-DATUM   " Date to find fiscal year for
IMPORTING
    CURRM         = w_currm.   " Current Fiscal Month
SELECT-OPTIONS s_currm FOR w_currm
               DEFAULT w_currm. " The default value is NOT being populated (appears blank)

Hi Venkat.O,
Thank you for your clear response. I have implemented your suggestion and it works, however, I now have a new problem.
Each time the report is executed or the "multiple selection" button is clicked the selection fields are populated once again with the default (low) values.
For example, when report is first opened the s_curry field displays '2010'. Clicking "multiple selection" results in another '2010' being populated. After executing the report the selection screen is populated again with '2010' (so we now have '2010' listed 3 times in the s_curry field).
How do I prevent the default values from repeating?
REPORT Z_DOWNLOAD_BSIS_TEST
*Data Declaration
DATA: w_currm TYPE BSIS-MONAT,
       w_curry TYPE BSIS-GJAHR,

How to kill the session after the user exit the ADF application

Dear all
I have a problem
The problem is the session still exist after the user close the application and the browser. I want to kill all sessions that is not active.
This is my test scenario:
1- I open IE and run my ADF application that is deployed on weblogic. http://192.168.100.17:7001/myapp/faces/login
2- At the same time I issue this SQL command to view the sessions for user 'ADFUSER' - the "ADFUSER" is the schema user.
SELECT USERNAME,STATUS FROM v$session
WHERE USERNAME = 'ADFUSER';QUERY RESULT IS
USERNAME                       MODULE                                           STATUS
ADFUSER                         JDBC Thin Client                                 INACTIVE3- Now the user close the browser
4- Run the SQL again and I notice that the session still exist
SELECT USERNAME,STATUS FROM v$session
WHERE USERNAME = 'ADFUSER'RESULT:
USERNAME                       MODULE                                           STATUS
ADFUSER                        JDBC Thin Client                                 INACTIVE5- now the user open the URL again http://192.168.100.17:7001/myapp/faces/login
6-Run the SQL again , and I notice that the old session still exists and a new session created too.
SELECT USERNAME,STATUS FROM v$session
WHERE USERNAME = 'ADFUSER'RESULT:
USERNAME                       MODULE                                           STATUS

2 rows selected.and every time I login to the application , a new session is open and the old session still exist
I do not know why this happens
I want to kill old session when the user close the application.
These sessions are cleared only when i restart the weblogic domain.
here is some information about my development environment:
Jdeveloper 11.1.2.3
WebLogic Server Version: 10.3.5.0
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
thanks in advance

Hi,
for performance reasons you should not use dedicated user connections to the database. Instead you use JDBC data sources (default in JDeveloper for ADF BC) that you can configure the database connection pooling for. This means that your v$session will always show a set of active session, which however are shared among users. Assuming you use ADF BC, this is what happens
- A user requests a data bound page
- The ADF BC checks out an AM and connects to the database using one of the database connections in the pool
... user work here ...
- user exits application
- ADF BC returns AM to pool and passivates pending user state (if application is left with dirty transaction)
- Database connection is available in pool as soon as AM released
This also happens between requests. Long story cut short: v$session doesn't give you a true picture

RFC enabled function module for insert update and delete in a Ztable..

friends..
Is there any standatd RFC enabled function module to insert , update and delete data in a custom database-table (Ztable)? if not how can we create it? plz give me the details steps..
what are the import, export parameters and how to develop and process it.. (for example: suppose fields in the table is Emp_Id, Name, Address)
Thanks and Regards

Problem while calling an RFC Function Module in Background

Hello,
I have created a RFC function module for reading data from an external DB system. The FM calls an external RFC program (coded in C++ using RFC SDK), which delivers the required data. This external program is maintainged as an TCP RFC Connection in SM59.
Further I have created a report, that calls the RFC function module to get the data from the external RFC programm.
My problem is, when I call the report in foreground, everything works OK, the RFC connection works and data can be read from the external program.
However, when I schedule the report to run in background as a job, the report is stating in the protocoll that there was a problem calling the defined RFC connection (although the connection is working properly at that time).
More funny is, this particular problem with running in background occurs only in the productive system, in test and development system the report works correctly also while running as a job in background.
Can you suggest the solution to this problem? Could it be something with authorisations or server settings?
I will be on holiday for the next 6 weeks, so take your time to answer .
Regards,
Dusan.

Please read the forum rules about u r g e n t ...

This is an external RFC server program, not a remote enabled ABAP RFC function module as the others seem to be assuming, right?
Is it possible that your DEV and QAS systems only have one application server, but the PROD has many and dedicated one(s) for processing low priority background jobs?
It might be that the target server of your TCP connection is not this BTC instance, and your RFC server is returning the data "locally" - so, into nirvana...
Just guessing, but might be worth checking.
Cheers,
Julius
