Calling a mething
how to call a method in a program is there any way like pattern to call a function module.
Yes,
Use Pattern button and select ABAP object Pattern....
Then fill in the correponding fields for your needs
ie:
Instance lo_sender
Class/Interface IF_PURCHASE_ORDER_ITEM_MM
Method CREATE_ACCOUNT
Thats all
Dont forget to reward!!!

CALL METHOD ABAP run SQL wrong
Dear All
I have a problem in ABAP connect SQL,Below is my code snippet sentence.
CONCATENATE 'Insert Into [timportcortrol]'
'(zucode,zstate,zdate,zkind) Values('''
VG_PCID ''','''
'1'','''
SY-DATUM ''','''
'1' ''')'
INTO SQL.
CALL METHOD OF REC 'Execute'
EXPORTING #1 = SQL
#2 = CON
#3 = '1'.
IF NOT SY-SUBRC = 0.
MESSAGE I000 WITH 'Download to [timportcortrol] failure，Please Check the SQL Connect!!! '.
EXIT.
ENDIF.
Con:is the connect SQL String ,the connect SQL is Okay.
I debug this code,when I used u2018Select u2026sentenceu2019,the program can work.if I use u2018insert intou2019 then canu2019t work,but I copied the SQL of the u2018inset Into sentenceu2026u2019run it into SQL server then it can work also.
And I found the SY-SUBRC eq u20182u2019.whatu2019s mean about of the sy-subrc eq u20182u2019.
I think the insert into sentence in abap I have write the wrong ,but I canu2019t assurance.
The Insert Into Sentence is:u2019 Insert Into [timportcortrol](zucode,zstate,zdate,zkind) Values('20080807094713','1','20080807','1')u2019
Could you give me some advice for this issue?
Thanks of all
Sun.Have you checked whether it's a problem with mixed case? Some SQL dialects are case sensitive.
The not very helpful meanings of the sy-subrc value can be found in ABAP help.

ABAP OOP / Calling Method ...Help
Trying out few oop codes....
While calling class instance methods and passing parameters, when to use the following syntax.
data: cvar type ref to class1.
cvar->method( exporting variable1 = value )
(or) some time i see sample codes with out key word 'exporting'
cvar->method( variable1 = value ) .
(or)
cvar->method( value ) .
(or) some times with key word CALL METHOD
CREATE OBJECT cvar
CALL METHOD cvar->method
EXPORTING
variable1 = value.
Tried out a uniform way of calling ,but getting errors.Any inputs please..
Thanks,
BvanBhavan,
First declare the class.
Implement the class.
Declare the Class reference variable
Create the class object.
call the method.
data: cvar type ref to class1.
CREATE OBJECT cvar
Calling Methods
To call a method, use the following statement:
CALL METHOD <meth> EXPORTING... <ii> =.<f i>...
IMPORTING... <ei> =.<g i>...
CHANGING ... <ci> =.<f i>...
RECEIVING r = h
EXCEPTIONS... <ei> = rc i...
The way in which you address the method <method> depends on the method itself and from where you are calling it. Within the implementation part of a class, you can call the methods of the same class directly using their name <meth>.
CALL METHOD <meth>...
Outside the class, the visibility of the method depends on whether you can call it at all. Visible instance methods can be called from outside the class using
CALL METHOD <ref>-><meth>...
where <ref> is a reference variable whose value points to an instance of the class. Visible instance methods can be called from outside the class using
CALL METHOD <class>=><meth>...
where <class> is the name of the relevant class.
When you call a method, you must pass all non-optional input parameters using the EXPORTING or CHANGING addition in the CALL METHOD statement. You can (but do not have to) import the output parameters into your program using the IMPORTING or RECEIVING addition. Equally, you can (but do not have to) handle any exceptions triggered by the exceptions using the EXCEPTIONS addition. However, this is recommended.
You pass and receive values to and from methods in the same way as with function modules, that is, with the syntax:
... <Formal parameter> = <Actual parameter>
after the corresponding addition. The interface parameters (formal parameters) are always on the left-hand side of the equals sign. The actual parameters are always on the right. The equals sign is not an assignment operator in this context; it merely serves to assign program variables to the interface parameters of the method.
If the interface of a method consists only of a single IMPORTING parameter, you can use the following shortened form of the method call:
CALL METHOD <method>( f).
The actual parameter <f> is passed to the input parameters of the method.
If the interface of a method consists only of IMPORTING parameters, you can use the following shortened form of the method call:
CALL METHOD <method>(....<ii> =.<f i>...).
Each actual parameter <f i > is passed to the corresponding formal parameter <i i >.

Example program for returninng and importing with value addition
HI ,
I want few example programs on how to use the abap oops with returning addition and importing with value addition as Im getting syntax error for the Program when Im declaring them with these additions
Thnaks .Hello,
This statement declares a general instance method meth. Use additions ABSTRACT and FINAL to make the method abstract or final.
The additions IMPORTING, EXPORTING and CHANGING define the parameter interface of the method. After every addition, the corresponding formal parameters are defined by a specification of the list parameters.
The other additions determine which exceptions the method can propagate or trigger and determine whether the method is abstract or final.
Note
Within a method, you can use the logical expression IS SUPPLIED to check whether an actual parameter was assigned to an optional formal parameter at the call.
Addition 1
... IMPORTING parameters PREFERRED PARAMETER p
Effect
IMPORTING defines input parameters. When calling the method, you need not specify an appropriate actual parameter for every non-optional input parameter. During the call, the content of the actual parameter is passed to the input parameter. The content of the input parameter - for which the reference transfer is defined - cannot be changed in the method.
Use PREFERRED PARAMETER to identify an input parameter p1 p2 ... of list parameters after IMPORTING as a preferred parameter. This specification makes sense only if all input parameters are optional. When calling the method with the syntax
CALL METHOD meth( a ).
the actual parameter a is assigned to the preferred parameter if you have appropriate use of a functional method at an operand position.
Addition 2
... EXPORTING parameters
Effect
EXPORTING defines output parameters. When calling the method, you can specify an appropriate actual parameter for every output parameter. The content of the output parameter - which is defined for value transfer - is passed to the actual parameter at the call after the method has been completed successfully.
Note
An output parameter that is defined for the reference transfer is not initialized when the method is called. Therefore, no read access to it should take place before the first write access.
Addition 3
... CHANGING parameters
Effect
CHANGING defines input/output parameters. When calling the method, you must specify an appropriate actual parameter for every non-optional input/output parameter. The content of the actual parameter is passed to the input/output parameter at the call, and after the method has been completed, the content of the input/output parameter is passed to the actual parameter.
Example
The method read_spfli_into_table of this example has an input and an output parameter, which are typed fully by reference to the ABAP Dictionary.
CLASS flights DEFINITION.
PUBLIC SECTION.
METHODS read_spfli_into_table
IMPORTING VALUE(id) TYPE spfli-carrid
EXPORTING flight_tab TYPE spfli_tab.
ENDCLASS.
Addition 4
... RAISING exc1 exc2 ...
Effect
Use addition RAISING to declare the class-based exceptions exc1 exc2 ... that can be propagated from the method to the caller.
For exc1 exc2 ..., you can specify all exception classes that are visible at this position and are subclasses of CX_STATIC_CHECK or CX_DYNAMIC_CHECK. You must specify the exception classes in ascending order corresponding to their inheritance hierarchy.
Exceptions of the categories CX_STATIC_CHECK and CX_DYNAMIC_CHECK must be declared explicitly, otherwise a propagation results in a violation of the interface. An interface violation results in a treatable exception CX_SY_NO_HANDLER. Exceptions of category CX_NO_CHECK are always implicitly declared.
Notes
The declaration of exceptions of category CX_STATIC_CHECK is checked statically at the syntax check. For exceptions of category CX_DYNAMIC_CHECK, the check is executed at runtime.
In a method in which class-based exceptions are declared with the addition RAISING, you cannot use the statement CATCH SYSTEM-EXCEPTIONS. Instead, handle the relevant treatable exceptions in a TRY control structure.
Example
In class math, you can propagate all exceptions represented by class CX_SY_ARITHMETIC_ERROR and its subclasses from within method divide_1_by. If, for example, the input parameter operand is filled at the call with the value 0, then the exception CX_SY_ZERODIVIDE is triggered, propagated, and can, as shown in the example, be handled by the caller in a TRY control structure.
CLASS math DEFINITION.

IMPORTING result = res ).
text = res.
CATCH cx_sy_arithmetic_error INTO exc.
text = exc->get_text( ).
ENDTRY.
MESSAGE text TYPE 'I'.
Addition 5
... EXCEPTIONS exc1 exc2 ...
Effect
Use addition EXCEPTIONS to define a list of non-class-based exceptions exc1 exc2..., which can be triggered with the statements RAISE or MESSAGE RAISING in the method. You specify identifiers exc1 exc2 ... for the exceptions to be defined at will and directly. Exceptions defined in this way are bound to the method - similar to formal parameters - and cannot be propagated.
If such an exception is triggered in a method and no return value has been assigned to it in the addition EXCEPTIONS of the CALL METHOD statement in the method call, then a runtime error occurs.
Note
The additions RAISING and EXCEPTIONS cannot be used simultaneously. For new developments starting at release 6.10, we recommend to use class-based exceptions, which are independent of the respective method.
Example
In the class math, for method divide_1_by an exception arith_error is defined, which is triggered in the method with the RAISE statement if an arithmetic error occurs. If, for example, the input parameter operand is filled with value 0 at the call, the exception arith_error is triggered in the method-internal handling of exception CX_SY_ZERODIVIDE and handled after the call of the method by evaluating sy-subrc.

class a{
public void meth()
System.out.println("In a");
class b extends a{
public void meth()
System.out.println("In b");
public class Test extends b{
public static void main(String[]a)
}can i call the a's meth() from Test without creating an instance of a? This might be a simple question and i think i cant create it, but if this is possible please tell me how to do it. also im not referring to runtime polymorphism. without using runtime polymorphism, can i access a's meth()? i know by calling super.meth() in b's meth() will solve it but i do not want to go that way.
Thanks in advance,
Geetmeth is not a static method of the class a, so you can't really call it without instantiating class a.
If you meant "can I call method meth in class a with an instance of class b?",(note that an instance of b is an instance of a) the answer is no as well, because your method from class b has overridden it... Note that you CAN call the method from class a from within class b (but not from Test), by using the keyword super. -
Pass the internal table with different structures to the class module
Hi ,
I have created a class method to fill up the data in XML format. the method can be called from various programs with internal table with different structures. I want to pass it as dynamic How can I do that.
I tried to declare that as type any.
but not working.
regards,
MadhuriHi,
You could work with data reference.
Use GET REFERENCE OF itab INTO data_ref for passing the internal table to your method, and dereference it within the method with ASSIGN statement...
DATA: lr_data TYPE REF TO data.
GET REFERENCE OF itab INTO lr_data.
CALL METHOD meth EXPORTING pr_data = lr_data.
METHOD meth.
FIELD-SYMBOLS <fs> TYPE ANY TABLE
ASSIGN pr_data->* TO <fs>.

ICCMP_BT_FOUP - How to call meth. 'DO_HANDLE_EVENT other Component/View?
Dear Experts,
when changing the field CONC_KEY-BTN in view BTSHeader in component ICCMP_BTSHEAD (Interaction Record Component)
the method DO_HANDLE_EVENT of the view controller is called.
The standard coding of the method is:
method DO_HANDLE_EVENT.
* Eventhandler dispatching
CASE htmlb_event_ex->event_server_name.
WHEN others.
global_event = super->do_handle_event( event = event
htmlb_event = htmlb_event
htmlb_event_ex = htmlb_event_ex
global_messages = global_messages ).
ENDCASE.
endmethod.
The component ICCMP_BTSHEAD is used in component ICCMP_BT_INR. Also visible in component ICCMP_BT_INR is the component ICCMP_BT_FOUP (View:CREATEFOLLOWUP) used to create Follow-Up Documents like Service Tickets.
What I want to is that, if the value of the field CONC_KEY-BTN is '1', the fields of the view CREATEFOLLOWUP follow-up-document have to be not modifiable. If the value of field CONC_KEY-BTN is '2' the fields are modifiable and it is possible to create a Follow-Up Document. That is my basic requierement. Better would be if the view CREATEFOLLOWUP would not visible if the value of the field CONC_KEY-BTN is '1'. But that would be more difficult I think?
To make the fields not modifiable, I think I have to modify the Get and Set Methods of the specific Atributes. But my problem is how can I modify the above mentioned method 'DO_HANDLE_EVENT' (View: BTSHeader) so that the event 'DO_HANDLE_EVENT' of the view controller of view CREATEFOLLOWUP is called at the same time (The problem is that the 'DO_HANDLE_METHOD of view CREATEFOLLOWUP is not called when changing the field CONC_KEY-BTN of the view BTSHeader ).
Best Regards
OliverHi Oliver,
In my opinion, the logic is not to be controlled at the do_handle_event level. ICCMP_BT_FOUP is created as a component usage right? So in the component ICCMP_BT_INR, there will be a navigation link defined with source as outbound plug of ICCMP_BT_INR and target as inbound plug of ICCMP_BT_FOUP. In this outbound plug, you can fill the param IV_DATA_COLLECTION as follows:
data: lr_current type ref to if_bol_bo_property_access,
lr_col type ref to if_bol_bo_col.
lr_current = me->typed_context->YOUR CONTEXT NODE->collection_wrapper->get_current( ).
check lr_current is bound.
create object lr_col
type
cl_crm_bol_bo_col.
check lr_col is bound.
lr_col->add( lr_current ).
Now pass this collection to the target inbound plug.
In the inbound plug of the target, you can control the logic based on the value of the attribute field in the collection.
I think this should work.

How to take back the control from RFC function module to calling program
Hi,
In our system landscape, more than 200 child systems are connected to Solution manager(SMP). I have copied a RFC enabled function module into all the child systems and calling that FM from Sol Man in sychronous mode.
Here goes my code in SolMan.
LOOP AT it_dest INTO wa_dest.
CALL FUNCTION 'Z_GET_LOGIN_DETAILS' DESTINATION wa_dest-rfcdest
EXPORTING
date_fr = s_date-low
date_to = s_date-high
TABLES
tab_data = it_val
EXCEPTIONS
communication_failure = 1
system_failure = 2
OTHERS = 3.
IF sy-subrc EQ 0.
* Updates zuserlogon
MODIFY zt_logon_det FROM TABLE it_val.
COMMIT WORK.
WRITE:/'RFC for Destination', wa_dest-rfcdest, 'succesfully updated.'.
ELSE.
WRITE:/'RFC for Destination', wa_dest-rfcdest, ' failed.'.
ENDIF.
ENDLOOP.
Few child systems are very slow & takes more than 20 minutes(Many of the times system hangs) to return the result. But I should not wait for so long. Even if the child system doesn't return any values in 5 minutes I shoud continue with other system ignoring the current one.
I tried calling the FM in asynchronous mode(STARTING NEW TASK) but no success because only 6 DIA processes possible but as I said I have more than 200 systems connected to SolMan.
Please help me resolving this problem.
Thanks,
PrathapIf there are only few child systems with bad response time, use asynchronous call using a CALL FUNCTION func STARTING NEW TASK task DESTINATION dest PERFORMING subr or CALLING meth ON END OF TASK. Count asynchronous calls still running/waiting (increment a counter when creating a task (not the one used for task id). In the form/method performed at end of a call decrement the counter. When counter is lower than a limit, 4-5 if 6 processes (*), perform an asynchronous call else perform a synchronous call or wait until the counter falls below the limit.

Can any one please help me I am having problem with me Iphone4, looks like the mic of my phone is not working. no one can hear me if I make a call to them. I have tried all restoring options but no use. please help me
The mic on my iPhone4 has just quit also. Similar symptoms to yours in that people I'm talking to hear only static or my voice very faintly. The voice/memo recorder also only really records static.
It happened suddenly and seemed to get better after a day or two but then went completely after another day.
I'm returning it to Vodafone New Zealand shortly but will have to wait 5-10 days for a replacement. There are NO Apple accredited means to speed this procedure up in NZ.

Hello All,
First of all sorry for posting the question in general abap queries, since somehow I am not able to post in ABAP objects discussions.
My requirement is
Step 1 : To get table name as input and dynamically derive all fields which is going to be passed as parameters for a method
I did this using cl_abap_typedescr class
Step 2: Then Pass the values into the relevant fields using below code
ptab_line-name = 'DATA_TAB'.
ptab_line-kind =
cl_abap_objectdescr=>changing.
GET REFERENCE OF text_tab INTO
ptab_line-value.
INSERT ptab_line INTO TABLE ptab.
Step 3: Later I am calling dynamic class like
CALL METHOD (class)=>(meth)
PARAMETER-TABLE
ptab
EXCEPTION-TABLE
etab.
I have read most of the post using Class cl_abap_typedescr=>describe_by_name to get parameter where I have to give correct parameter type.
But my issue is that I also need to know which fields are acting as importing , exporting and changing parameter.
Is there anyway to determine and pass method's paramter type as well ?
Thanks!

RamyaMight be I can use table view VSEOMEPARA

Using a dynamic variable in the Import command of a Method call
Hi,
I am trying to make a Method call fully dynamic.
I have found out how to make the Method name dynamic, but I am having trouble figuring out how to make the Importing statement dynamic.
in my code below:
CALL METHOD o_main->(v_call)
IMPORTING
it_ekko = i_ekko.
I would like to know if it's possible to make both "it_ekko" AND "i_ekko" dynamic so I can use this same call for various tables.
Hope that makes sense...thanks for your help.

Using reflector to call a method on an objectRef
hey all! i have the following code to call a function to the objectRef that i keep in an array (jobServers) ...
// jobServers[0].objServerRef.addService(theCallbackObjectRef, number, jobServers);
Class c = Class.forName("WorkflowFramework.Job");
System.out.println(jobServers[0].functionName);
Method meth = c.getMethod(jobServers[0].functionName);
meth.invoke(jobServers[0].objServerRef, theCallbackObjectRef, number, jobServers);
but i get the following error :
addService
FileClient Error: WorkflowFramework.Job.addService()
java.lang.NoSuchMethodException: WorkflowFramework.Job.addService()
at java.lang.Class.getMethod(Unknown Source)
at Client.main(Client.java:123)
in the first line i print the name of the function (addService) that i want to be called, and it is correct. Then i see that the function is called on the WorkflowFramework.Job and not on the jobServers[0].objServerRef which is an object of instanse Job.
The addService function exists there because the declaration that is now in commends is running just fine if i take out the commends..
Do you think the problem lies in the fact that Job is actually an interface declared like :
//the job interface to enable client to choose services.
public interface Job extends JobOperations, org.omg.CORBA.Object, org.omg.CORBA.portable.IDLEntity
} // interface Job
the addService function is declared in the JobOperations...
any help plzzz?well.. you are kind of right...
i write them as a struct in the IDL and the it is
automatically transformed in the following java Class
public final class lineArrayServers implements
org.omg.CORBA.portable.IDLEntity
public WorkflowFramework.Job objServerRef = null;
public String functionName = null;
public lineArrayServers ()
} // ctor
public lineArrayServers (WorkflowFramework.Job
_objServerRef, String _functionName)
objServerRef = _objServerRef;
functionName = _functionName;
} // ctorand then i wrap it in an array of these.. the
jobServers...aha. so struct is an IDL construct in this case. I've never written any IDL, but I have written 'C', hence the confusion!

Calling methods from Command prompt
Hi,
OK this may seem crazy:).
Is it possible to call a method from the command prompt directly?.
For eg. I have a class UFOSeeker that has a static method getPosinSky.
Is it possible to just call this method directly form the cmd prompt?, something like this
[neo@zeno ~]java UFOSeeker.getPosinSky()
The . is wrong i know, but is there a way?.
Reason for asking this, just bored and wondering whether this would be possible?.
TIA,
krisYou could do it via another class and use reflection.
For example:
public class CallStaticMethod
public static void main(String[] args)
String className = args[0].substring(0, args[0].lastIndexOf('.'));
String methodName = args[0].substring(args[0].lastIndexOf('.')+1, args[0].indexOf('('));
try
Class clazz = Class.forName(className);
Method meth = clazz.getMethod(methodName, new Class[0]);
meth.invoke(null, new Object[0]);
catch ( Exception e )
e.printStackTrace();
}You would then run:
java CallStaticMethod package.Class.method()
or in your example
java CallStaticMethod UFOSeeker.getPosinSky()
The code above does not do anything about passing in parameters or getting return types. If you are really bored you could add it in. -
