Calling two BAPIs in the sequence in same transacon

Hi ,
I am caling Two BAPIs in a sequnce in MII Transaction. I am using Jco Interface for this. My first Bapi is getting called and for second bapi call , I am etting the following error.
Problem retrieving JCO.Function object: Function [] not found.
Now I would like use session action and in session I will be calling two function with bapis and if something goes wrong i have to roll back the session. suggest me the sequnce of steps.
Thanks, Eswar

Hi Rohit,
Thanks for the reply.
I have used JCo interface for calling two bapis and i have given time delay of 5 seconds between calls and it served my purpose.
Thanks , Eswar

How can I call a function via two different eventListener, is it possible?

Hi...
I want to call one function two different way... I write following code, but an error appears..
Could you help me.. ?
Thanks...!
/******************************** LET'S CALL VIA TWO DIFFERENT EVENTLISTENER A FUNCTION ***********************************************/
var trigger:Timer = new Timer(1000, 10);
function showAll(evt:TimerEvent, olay:MouseEvent):void{
/* code blocks */
increase_btn.addEventListener(MouseEvent.CLICK, showAll);
trigger.addEventListener(TimerEvent.TIMER, showAll);
trigger.start();

var trigger:Timer = new Timer(1000, 10);
function showAll(evt:*):void{
/* code blocks */
increase_btn.addEventListener(MouseEvent.CLICK, showAll);
trigger.addEventListener(TimerEvent.TIMER, showAll);
trigger.start();
Just change the showAll as shown - * is a wildcard - any object/event will work.
You can also do like:
function showAll(evt:* = null):void{
By putting the = null you can call it with the events or just call it like showAll(); if you need.

Can two functions call each other?

I'm converting some code and have run into two functions that call each other. While I seem to have converted both functions to plsql ok, they do not compile, seemingly because they ref each other. As soon as I de-reference one one function's call to the other function they both compile.
I know that Oracle 10g supports recursion; and on the surface of things, this situation does not seem much different than recursion. If both functions are well formed, I would hope that they'd compile.
I wasn't able to find much by searching the forums on this topic...but I'm hoping that someone will have some info on this issue.

Passing arrays with Call Library Function does not work after application builder

Calling a DLL with Call Library Function which requires an array of data works correctly in Labview, but after building an exe with application builder, the call no longer works. Dereferecing the pointer in the DLL retuns all 0s and not the actual values.
Solved!

I did not run your code because it is a little unclear to me what it does.
Two things:
First, is the DLL you are calling the DLL-ified version of PopUpNames.vi? Then the problem is likely that the panel is not being built into the DLL.
When LabView builds an application / dll, it strips the front panel and block diagram from all VIs that it doesn't think need to show a panel at run time. This reduces file size and increases code security. The App Builder's panel inclusion logic can be overridden by Build Specifications -> Source File Settings -> Remove front panel. A better method is to put a property node on a control in a window you want to show marking it "visible"; this is sufficient to tell the App Builder it should keep the panel.
Currently Source File Settings shows "no dependencies" (clearly incorrect---another evil side effect of Express VIs I guess) but if you change the settings as shown below to keep ALL panels, one might hope the App Builder can figure it to keep the panel when it deconstructs the Express VI. (Alternatively convert the Express VI into a regular one.)
A second comment: I am a bit flummoxed at the larger goal here. You are calling LabView DLL from LabView, which doesn't make a lot of sense, so I assume your larger goal is to call LabView from C or vice-versa. In that case be aware that your DLL is x86 (32-bit) but you are passing 64-bit ints as your pointers. In this case it is 32-bit LabView with 32-bit pointers in embedeed in 64-bit containers calling 32-bit LabView with 32-bit pointers in embedeed in 64-bit containers, so it all works, but if your going to call this from C or whatnot you're going to have to follow that same design.
When calling C code the LabView Call Library Function does have a "unsigned pointer-sized integer" data type that always appears to be 64 bits in the dev env but which actually passes a 64 or 32-bit int to the DLL depending on the environment. The "pointer sized int" has to be 64 bits in the "LabView" part of the code because LabView's strong typing requires the data type to be determined at compile time. Casting all pointers to the largest data type in LabView makes it possible to write platform-independent code, but down at the Call Library level you still have to put the right number of bytes on the stack.

Bug in Apex 2.2.1.00.04 in overload call of function?

We are having custom table defined as:
CREATE TABLE HTMLDB_USERS (
ID             INTEGER               CONSTRAINT HTMLDB_USERS_ID_NN NOT NULL,
USERNAME       VARCHAR2(64 BYTE)     CONSTRAINT HTMLDB_USERS_USERNAME_NN NOT NULL,
desc htmldb_users Name                                      Null?    Type
ID                                        NOT NULL NUMBER(38)
USERNAME                                  NOT NULL VARCHAR2(64)
...Where ID is primary key and on USERNAME there is unique index defined.
In package we have two overload functions defined as:
FUNCTION update_password (
            p_id       IN HTMLDB_USERS.ID%TYPE
           ,p_password IN HTMLDB_USERS.PASSWORD%TYPE
          ) RETURN PLS_INTEGER;and later declared:
FUNCTION update_password (
            p_username       IN HTMLDB_USERS.USERNAME%TYPE
           ,p_password IN HTMLDB_USERS.PASSWORD%TYPE
          ) RETURN PLS_INTEGER;which should be correctly determined in call according different data types. In our page we had a call like:
:P102_STATE :=#OWNER#.pkg_auth.update_password(:P102_ID,:P102_NEW_PASSWORD2);
...Call was going to correct function (the one with ID in parameter).
In trace (have special pragma function for writing values to database) we get that passed values all the time was "-2", regarding that "P102_ID" was having correct INTEGER value ("3", "4", "7" etc...).
Interesting thing was that call with v('P102_ID') in function results OK!
When we place call by reference
p_id=>:P102_ID,p_password=>:P102_NEW_PASSWORD2);Then all was OK!
We are pointing to this bug because it may raise many problems to users....
select * from v$version;BANNER

TNS for 32-bit Windows: Version 10.2.0.1.0 - Production

Vikas,
all clear but that v('P102_ID') call is bothering me!
And other thing....I was debugging in first function (with number parameter)...and if API is making VARCHAR2 value, then in no circumstances first function (with number) cannot be called but only second one (with two VARCHAR2)...which was not called !!!!
To make more clear, create two function (in this order in package):
FUNCTION update_password (
            p_id       IN HTMLDB_USERS.ID%TYPE
           ,p_password IN HTMLDB_USERS.PASSWORD%TYPE
          ) RETURN PLS_INTEGER;
BEGIN
dbms_output.put_line(v('P102_ID'));
dbms_output.put_line('Number called function "'||to_char(p_id)|'"');
return null;
END;
FUNCTION update_password (
            p_username       IN HTMLDB_USERS.USERNAME%TYPE
           ,p_password IN HTMLDB_USERS.PASSWORD%TYPE
          ) RETURN PLS_INTEGER;
BEGIN
dbms_output.put_line(v('P102_ID'));
dbms_output.put_line('VARCHAR2 called function "'||p_username||'"');
return null;
END;and make a call like in my case.
This is most interesting of all! Intersting which function will be called!
Maybe this note helps someone to be mislead...

How to call two RFC in a single JAVA method.

Dear all,
I just want to know that how to call two RFC in a single java method which is defined in CRM implementation file. I'm using NWDS as the customization IDE & working on ISA 7.0.

Hi Sunil,
In the Backend Implementation class, in any method you can call multiple RFCs.
It will be the same way as you do for the single RFC call.
Following syntax is for your reference.
Get the JCO connection
JCoConnection connection = getDefaultJCoConnection();
JCO.Function func = connection.getJCoFunction("ZXXXXXXX");
set the import parameters
Execute it.
connection.execute(func);
get the data from export / table parameters
Now call the second RFC
func = connection.getJCoFunction("ZYYYYYYYYYY");
set the import parameters
Execute it.
get the data from export / table parameters
close the connection
Hope this will help you.
-Chandra.

How to call two data blocks at a time.

hi all
i want to call two data blocks at a time on function when button pressed.
how can I it?
many thanks

Many thanks that you people reply,
I am working in oracle form developer 6i and database 10g.
I have a form that have three data blocks,
first block have text boxes and search button,and next two blocks display records on the basis of search criteria that is inserted in the first block and when is clicked on save button.
the data that is to b displayed is from two different tables.
i used Go_block('my_block')
and call other block with the same method.
kindly guide me how can i do it.
Thanks in advance

Calling a function module from within a transformation routine

I created a routine within a transformation and experience the following weird behavior now:
When I call a function module within that routine, the load fails with the following error message:
Exceptions in Substep: Rules
When I click on the button next to this text, it point me to my function module call.
What I do not understand is, that the following two scenarios work fine:
- Having the same function call (with fake values) in a plain ABAP program works beautilfully
- If I copy the content of my function module directly into my transformation routine, everything works fine as well
I am now wondering whether the routine does not "see" the function module I am calling. The module resides in a different package. Is that a problem? Do I have to include something first?
Here is the code that calls my FM (
CALL FUNCTION 'Z_CA_CONVERT_US_COST'

       OTHERS                    = 3.
Thanks a lot for your help. Points will be assigned.

Good catch, BI Learner. This was exactly it: when assigning the values from SOURCEFIELDS directly to the import/export parameters, you have to make sure that the types are EXACTLY the same, otherwise it will not work (the routine stops with an error when calling the FM, but there is no dump).
Therefore, to solve my problem, I created the declarations precisely as expected by the FM and assigned the values to these fields:
DATA:
      SOURCEVAL TYPE /BIC/OIINVQTY,
      SOURCEUOM TYPE /BIC/OIUSUOM,
      USITM TYPE /BIC/OIUSITM,
      TARGETUOM TYPE /BIC/OIUSUOM,
      CONVERTED_COST TYPE /BIC/OIINVQTY.
DATA PRODUCTION_UOM TYPE /BIC/OIUSUOM.
" get the Production UOM
    SELECT SINGLE I~/BIC/USPRDUOM
      FROM /BIC/PUSITM AS I
      INTO PRODUCTION_UOM
      WHERE I~/BIC/USITM = SOURCE_FIELDS-/BIC/USITM AND I~OBJVERS = 'A'.
    IF ( SY-SUBRC = 4 ). " no records found
      "RAISE PARTNO_NOT_FOUND.
      RAISE EXCEPTION TYPE CX_RSROUT_SKIP_RECORD.
    ENDIF.
" load the parameters
    SOURCEVAL = SOURCE_FIELDS-/BIC/USFRZMFC.
    SOURCEUOM = SOURCE_FIELDS-BASE_UOM.
    USITM = SOURCE_FIELDS-/BIC/USITM.
" then you can call the FM
    CALL FUNCTION 'Z_CA_CONVERT_US_COST'
      EXPORTING
        PSOURCEVAL                = SOURCEVAL
        PSOURCEUOM                = SOURCEUOM
        PUSITM                    = USITM
        PTARGETUOM                = PRODUCTION_UOM
      IMPORTING
        PTARGETVAL                = CONVERTED_COST
      EXCEPTIONS
        CONVERSION_NOT_MAINTAINED = 1
        PARTNO_NOT_FOUND          = 2
        OTHERS                    = 3.

Calling GUI_DOWNLOAD Function

i would like to store my internal table into my local disk , there are two functions GUI_DOWNLOAD and WS_DOWNLOAD.
how do i call these functions.
if i want to specify the file name in my selection screen what should be the data type of the file name.
when i call the function GUI_DOWNLOAD , there is an error saying mismatch of datatype of filename.

Dear Rajarshi,
I gave the file name as a paramater with type c length 30 , but it is still showing the same error
The message is given below --
'The function Module interface allows you to specify only fields of a particular type under"FILENAME". The field PATH specified here has a different field type'
Please do suggest some solution.

SQL query slow with call to function

I have a SQL query that will return in less than a second or two with a function in-line selected in the "from" clause of the statement. As soon as I select that returned value in the SQL statement, the statement takes from anywhere from 2 to 5 minutes to return. Here is a simplified sample from the statement:
This statement returns in a second or 2.
select A.pk_id
from stu_schedule A, stu_school B, stu_year C, school_year D,
(select calc_ytd_class_abs2(Z.PK_ID,'U') ytd_unx
from stu_schedule Z) II
where B.pk_id = A.fk_stu_school
and C.pk_id = B.fk_stu_year
and D.pk_id = C.year
and D.school_year = '2011';
if I add this function call in, the statement runs extremely poor.
select A.pk_id,
II.ytd_unx
from stu_schedule A, stu_school B, stu_year C, school_year D,
(select calc_ytd_class_abs2(Z.PK_ID,'U') ytd_unx
from stu_schedule Z) II
where B.pk_id = A.fk_stu_school
and C.pk_id = B.fk_stu_year
and D.pk_id = C.year
and D.school_year = '2011';
Here is the function that is called:
create or replace FUNCTION calc_ytd_class_abs2 (p_fk_stu_schedule in varchar2,
p_legality in varchar2) return number IS
l_days_absent number := 0;
CURSOR get_class_abs IS
select (select nvl(max(D.days_absent),'0')
from cut_code D
where D.pk_id = C.fk_cut_code
and (D.legality = p_legality
or p_legality = '%')) days_absent
from stu_schedule_detail B, stu_class_attendance C
where B.fk_stu_schedule = p_fk_stu_schedule
and C.fk_stu_schedule_detail = B.pk_id;
BEGIN
FOR x in get_class_abs LOOP
l_days_absent := l_days_absent + x.days_absent;
END LOOP;
return (l_days_absent);
END calc_ytd_class_abs2;

Query returns anywhere from 6000 to 32000 rows. For each of those rows a parameter is passed in to 4 different functions to get ytd totals. When I call the functions in the in-line view but do not select from them in the main SQL, the report (oh, this is Application Express 4.0 interactive reports, just an FYI) runs fast. The report comes back in a few seconds. But when I select from the in-line view to display those ytd totals, the report runs extremely slow. I know there are the articles about context switching and how mixing SQL with PL/SQL performs poorly. So I tried a pipeline table function where the function for the ytd totals populate the columns of the pipeline table and I select from the pipeline table in the SQL query in the interactive report. That seemed to perform a little worse from what I can tell.
Thanks for any help you can offer.

How to call a function module in VC

Hi,
I want to call a function module for an addition formula which shall calculate and infer the value.
eg. quantities of 5 different characteristics (of numeric data) is to be summed up and inferred against the 6th characteristic.
I want to know the detailed process to create a Variant Function and use it in a dependency.
Request to please advise the steps, type of dependency and its code.
Regards,
Rajesh Mohapatra

Dear Rajesh,
I also wanted to learn how to do that, your post motivated me to use a bit of freetime and investigate on the subject. I finally made my function work, so here are the tips.
The example is very simple, just a variant function with two inputs and which multiplies inside the input values and transfer that result to the output ( 3 x 4 => 12 ).
Deducting how to add five values or any other logic would be easier starting from there.
STEP 1: Create Variant Class for the product. I imagine you already have that. In my case its name is ZVC_CLASS, you have already a material assigned to the class, a configuration profile, etc....
STEP 2: Create Three Characteristics Z_NUM_CH_1,Z_NUM_CH_2,Z_NUM_CH_3 the three of numeric type
STEP 3: Assign characteristics from step 2 into class ZVC_CLASS
STEP 4: Create the function module with the code given below. I put the name ZVC_FUN_TEST
FUNCTION ZVC_FUN_TEST.

STEP 5: Activate the function module for Variant Configuration in transaction CU65, put there your function module, release int and in button characteristics write Z_NUM_CH_1,Z_NUM_CH_2,Z_NUM_CH_3. Flag the first two lines as they are inputs.
STEP 6: Create a Dependency ZVC_PROC_TEST of type Procedure to call the function with this code:
000010 Function ZVC_FUN_TEST
000020 (Z_NUM_CH_1 = $root.Z_NUM_CH_1,
000030 Z_NUM_CH_2 = $root.Z_NUM_CH_2,
000040 Z_NUM_CH_3 = $self.Z_NUM_CH_3)
STEP 7: Lets say I want to calculate the multiplication only upon the selection of another characteristic "Calculate" YES/NO. For this I create a characteristic in CT04 Z_CALCULATE type CHAR 1 with possible values Y or N. For the value Y y add the procedure ZVC_PROC_TEST so that formula only activates on Y.
STEP 8: Add characteristic Z_CALCULATE to class ZVC_CLASS
STEP 9: VA01, it should work

Can one call a function module in Calculated Key Figure?

Can one call a function module in Calculated Key Figure? If yes how, if not, what is the solution if formula does not suffice?
I want to convert duration which is in seconds to Duration in Hours and Minutes. There is a function module for doing it. Not sure how to do it in a formula.

One option you have is a Virtual Key Figure and User Exit to use the Function Module to convert the time from seconds to HH:MM. Here are two documents on this subject to help you create them, based on the technology your comfortable with:

Can I call a function from a dll in LabVIEW that returns:double*string and int.?

I have a function from a dll that return a double* string and an integer. How can I call this function from LabVIEW? There is a possibility to work in LabVIEW with a double* string?

Two difficulties I can see with this.
First the application seems to allocate the array of references
internally and return a pointer to that array. In that case there must
be another function which then deallocates that array again.
Then you would need to setup the function call to have a pointer to an
int32 number for the deviceList parameter and another pointer to int32
one for the plItems parameter.
Then create another function in your DLL similar to this:
HRESULT WRAPIEnumExtractDevice(WRAPI_NDIS_DEVICE *lpDeviceList, long i,
CHAR lpszDeviceName, LONG lenDeviceName,
CHAR lpszDeviceDesc, LONG lenDeviceDesc)
if (!lpDeviceList)
return ERROR_INV_PARAMETER;
if (lpDeviceList[i].pDeviceName)
WideCharToMultiByte(CP_ACP, 0,
pDeviceList[i].pDeviceName, -1,
lpszDeviceName, lenDeviceName,
NULL, NULL);
if (lpDeviceList[i].pDeviceName)
WideCharToMultiByte(CP_ACP, 0,
pDeviceList[i].pDeviceDescription, -1,
lpszDeviceDesc, lenDeviceDesc,
NULL, NULL);
return NO_ERROR;
Pass the int32 you got from the first parameter of the previous call as
a simple int32 passed by value to this function (and make sure you don't
call this function with a higher index than (plItems - 1) returned from
the first function.

Can I call a function in another package?

Dear all,
Can I call a function in another package?
Say I have package A, and package B.
Is it possible for me to call a function in inside package A, within a function inside package B?
If yes, what's the syntax.
Thanks in advance!

The variable in the calling package that will receive the value of the function in the other package needs to be defined based on that type in the other package directly:
sql>create or replace package pkg_a
2 is
3    type testTable is table of varchar2(10) index by binary_integer;
4
5    function f_a return testTable;
6 end;
7 /
Package created.
sql>create or replace package body pkg_a
2 is
3    function f_a
4      return testTable
5    is
6      v_table testTable;
7    begin
8      v_table(1) := 'One';
9      v_table(2) := 'Two';
10      return v_table;
11    end;
12 end;
13 /
Package body created.
sql>create or replace package pkg_b
2 is
3    procedure p_b;
4 end;
5 /
Package created.
sql>create or replace package body pkg_b
2 is
3    procedure p_b
4    is
5      v_table pkg_a.testTable; -- this variable has to be based on the type in pkg_a
6    begin
7      v_table := pkg_a.f_a;
8      for i in 1..v_table.count loop
9        dbms_output.put_line( v_table(i) );
10      end loop;
11    end;
12 end;
13 /
Package body created.
sql>exec pkg_b.p_b
