Regarding creation of function module.

hi experts,
can anybody help me to know how to create a function module.
regards,
joy.

Hi joy,
Goto SE37, give a Z- or Y- name and hit create.
Assign it to an already existing function group (or create a new one thru SE80) give the short name.
Give the import & export parameters.
If import/export is gonna thru tables, fill out tables.
Fill the exceptions if you like to.
Then write your code in the source code tab.

BAPI creation versus function module creation...

Hi,
I know the difference between BAPI and simple function module. I have also created custom function module.
But I have not worked on creation of Custom BAPIs.
Is there a much differece in creation of function module and BAPI?
If there is please throw some light on main differences or stepwise differences when I create BAPI versus function module ?
Thanks.
Regards,
Tushar.

Hai Tushar
what is BAPI?
BAPI stands for Business API(Application Program Interface).
I have answered this question before..
A BAPI is remotely enabled function module ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
You can make your function module remotely enabled in attributes of Function module but
A BAPI are standard SAP function modules provided by SAP for remote access. Also they are part of Businees Objest Repository(BOR).
Please check out this thread..

Java Connector(JCO) can call not only BAPI's but also the function modules which are remotely enabled..
BAPI's as i said earlier are remotely enabled function modules..
Hence, JCO can call also BAPI's(n not only BAPI's as u mentioned).

Error with quantity field:Datasource Creation Using Function Module method

Problem with DATASOURCE Creation using Function Module method :
I have created a datasource ZSTANDARD_COST_PRICE using Function Module method . The datasource creation is successfull when I remove the quantity field from the Z table . If I dont remove the quantity field from my Z table it gives an error as "Units Field WAERS for field STPRS of datasource ZSTANDARD_COST_PRICE is hidden". I am not able to remove this error . Please someone guide.
Let me know if my explanation is not clear enough.
Thanks in advance,
Neha.
Z table definition is as below :
MATNR MATNR CHAR 18 0 Material Number
BWKEY BWKEY CHAR 4 0 Valuation area
LFGJA LFGJA NUMC 4 0 Fiscal Year of Current Period
STPRS STPRS CURR 11 2 Standard Price " Here the currency field is WAERS and table T001
PEINH PEINH DEC 5 0 Price Unit
VJSTP VJSTP CURR 11 2 Standard price in previous year
VJPEI VJPEI DEC 5 0 Price unit of previous year.
Edited by: Neha Rathi on Jan 30, 2009 3:03 PM

Hi,
You should add it as one of the main fields as you have added other fields and not as the currency fields...that is..it should be part of the data source and you should be able to see it in RSO2...
Also if added as i said then it will come as new field in the data source...you can either let it be there...or hide it..
also if you want to populate it then you will have to write the code for this fields as well.
Thanks

Regarding the Remote Function Module

hi,
Can any body can provide the brief information regarding the Remote Function Module.
1)How to create the remote function module
2)how it differ from the normal function module
3)any special features about this.
Thanks in advance

Hi
RFC (Remote Function Call) is similar to the general SAP fun module: except that in the attributes you click the radio button: RFC enabled;
and you will be passing an Import parameter DESTINATION to it.
Other code and usage will be similar to any fun module;
Have a look at any fun module in SE37 to understand better about the different components of Fun modules;
Refer this link:
http://help.sap.com/saphelp_nw04/helpdata/en/22/042518488911d189490000e829fbbd/frameset.htm

Function Modules;
Check this matter.
Function Modules are Global ABAP programs created by SAP for reusable purpose.they have IMPORT,EXPORT and TABLE parameters, and EXCEPTIONS to through when error occurs.
You can create them from TCode SE37.
Go through the following doc:
Function modules are cross-program, reusable procedures that are organized into function groups, and whose functions are implemented between the statements FUNCTION and ENDFUNCTION. Function modules and their interfaces are created in the Function Builder.
Function Module Interfaces
The parameter interface of a function module is defined in the Function Builder. It includes the definition of interface parameters and the specification of exceptions that can be triggered by a function module. The Function Builder automatically generates comment lines below the FUNCTION statement in the source code of the function module, which represent the interface of the function module with the following syntax:
Syntax
... [IMPORTING parameters]
[EXPORTING parameters]
[CHANGING parameters]
[TABLES table_parameters]
[{RAISING|EXCEPTIONS} exc1 exc2 ...]
The syntax and semantics of IMPORTING, EXPORTING, CHANGING, RAISING, and EXCEPTIONS mainly correspond to the definition of method interfaces with [CLASS-]METHODS. The additional option of defining table parameters using TABLES is obsolete.
Interface parameters
The interface parameters are defined on the relevant tab pages in the Function Builder.
IMPORTING parameters are input parameters. When the function module is called, a suitable actual parameter must be specified for every non-optional input parameter. The content of the actual parameter is passed to the input parameter when the call is made. The content of an input parameter for which 'pass by reference' is defined cannot be changed in the function module.
EXPORTING parameters are output parameters. When the function module is called, a suitable actual parameter can be specified for every output parameter. The content of an output parameter that is defined for 'pass by value' is transferred to the actual parameter if the function module is completed without errors. An output parameter that is defined for pass by reference is not initialized when the function module is called.
CHANGING parameters are input and output parameters. When the function module is called, a suitable actual parameter must be specified for every non-optional input or output parameter. When the function module is called, the content of the actual parameter is passed to the input/output parameter, and when the function module is completed, the content of the input/output parameter is passed to the actual parameter.
TABLES parameters are table parameters. Table parameters are obsolete CHANGING parameters that are typed as standard tables with a header line. If an internal table without a header line or a table body is passed as an actual parameter to a formal parameter of this type, an empty local header line is generated in the function module. If an internal table with a header line is used as an actual parameter, both the table body and the header line are passed to the function module. Pass by value is not possible in formal parameters defined using TABLES. Formal parameters defined with TABLES can be replaced by formal parameters defined with CHANGING. A local work area can be created for the internal table in the function module by using the addition LIKE LINE OF itab of the DATA statement.
Exceptions
The exception of a function module are defined on the Exceptions tab page in the Function Builder. Here you can select exception classes to define whether class-based exceptions are declared or non-class-based exception are defined. Class-based exceptions are represented in the above syntax by RAISING, and non-class-based exceptions are represented by EXCEPTIONS.
The addition RAISING is used to declare class-based exceptions that can be propagated from the function module to the caller. Exceptions in the categories CX_STATIC_CHECK and CX_DYNAMIC_CHECK must be explicitly declared, otherwise a propagation can lead to an interface violation. A violation of the interface leads to the treatable exception CX_SY_NO_HANDLER. Exceptions of the category CX_NO_CHECK are implicitly always declared. The declaration of exceptions of the category CX_STATIC_CHECK is statically checked in the syntax check. For exceptions of the category CX_DYNAMIC_CHECK, the check is not performed until runtime. In a function module in which class-based exceptions are declared with the RAISING addition, the statement CATCH SYSTEM-EXCEPTIONS cannot be used. Instead, the relevant treatable exceptions should be handled in a TRY control structure.
The addition EXCEPTIONS is used to define a list of non-class-based exceptions that can be triggered in the function module using the statements RAISE or MESSAGE RAISING. Exceptions defined in this way - as with formal parameters - are bound to the function module and cannot be propagated. If an exception of this type is triggered in a function module, and no return value has been assigned to it with the homonymous addition EXCEPTIONS of the CALL FUNCTION statement when the call was made, this leads to a runtime error.
Note
For new developments after release 6.10, SAP recommends that you work with class-based exceptions that are independent of the function module.
RFC is a technology which is used to access a functions (Modules) from
the remote systems.
If a function module is set as remote enabled which can be access from
the remote system via RFC.Eg: U can access the Remote enabled function modules in ur VB,Webdynpro,Java,Visual composer program.
A function module can be set as remote enabled by SE37->Go to ur FM->click the option Button "remote enabled".
But Normal function modules can not accessd from the remote system.
Good Example for RFC enabled function module is : BAPI(Business Application Programming Interface)
Note: All BAPIs are Remote enabled but not all remote enabled function modules are BAPI.
CALLING A FUNCTION MODULE:
1)In U ABAP Editor --> Click "Patter" ---> Selection Option Button "Call Function"
--> Write the Corresponding FM name --> Hit Enter
2)The appropriate import ,export Parameters will be displayed in ur editor
3)Pass the Values Here.

Save EAN11 field while creating POrder creation through Function module

Hi All,
I want to update EAN11 field in material master while creating Purchase Order through function module. I am using function module BAPI_PO_CREATE1 for creating purchase order. There are no structures in the PO creation FM in which EAN11 field is there. I have also tried using function module MEPO_DOC_ITEM_PROCESS for updating EAN11 field. It is not working. Please suggest some method to do that.
Note: I am receiving EAN11 through an external system by proxy.
Thanks,
Chinmay

Hi,
Use BAPI_MATERIAL_SAVEDATA to updat ean numbers for materials.
tables INTERNATIONALARTNOS is used to update EAN.

How to automate the creation of Function Module & Class Object (SE24)

Experts,
I have the requirement to automate the creation of any type of programs: ie function module (like how we normally create in SE37 together with the parameters), class object (like how we normally create in SE24 together with attribute & method), normal report (like how we did in SE38), module pool and so on.
For example. I backuped my program into a flat file (the entire source code in txt formal or HTML) through a download program and I need to upload back this flat file into another installation of SAP.
Does SAP provide any predefined FM to cater for the above cases or better still, does anyone know of any upload program which I can use for the above requirement.
Thanks in advance.

Hi Kris, I can't use the transport system as these are 2 separate SAP installation in a different place. The requirement came in the form of creation of program to be able to generate FM/Class/Report on the go.

Creation of function module for updating the ztable

Hi,
I am sending the requirement for ceation of function module for updating the ztable.
Requirement----
Table Updation rule (New record)
While creating a new record the calling function will export the following to the table handling function.
Table field     Probable Values
ZORDERNO------->     Sales Delivery no in case of sales orderShipment no in case of transfer order
UNAME----
>     User ID
ZORDTYPE----
>     SALEOR in case of sales orderTRANSF in case of transfer order
ZREFDOCNO----
>Sales Order no in case of sales orderPurchase Order no in case of transfer order
ZREFDOCNO1----
>Delivery no in case of transfer order
The table handling function will calculate the following fields
Table field     Probable Values
ZREQNO----
>Running serial number (incremented by 1 for each new record)
ZREQDAT     -
>System date
ZREQTIME----
>     System time
ZSTATUS----
>OPEN (for all new records)
Before inserting a new record the table handling function will always check if a previous record exists for the same order / shipment no. if record exists the function will not insert a new record.
Table Updation rule (Status Update)
While updating a record the calling function will export the following to the table handling function.
Table field     Probable Values
ZORDERNO----
>Sales order no in case of sales orderShipment no in case of transfer order
ZSTATUS----
>CANCEL if cancellation successfulERROR if cancellation not possible (order already processed)
The table handling function will calculate the following fields
Table field     Probable Values
ZSTATDAT----
>System date
ZSTATTIME----
>     System time

Do you have to create/update new record in Ztable through Function Module ?
or you need to write FM only for validation?
Any how, you need to create a Program with Input values for the fields of Ztable, and for rest of fields the Value can be calculated based on input as per your requirement.
Let me know clearly what exactly u need ?

Kiran

In creation of function module

hi,
i created one rfc enabled function module to update the database table agr_define. but, is it possible to create custom function module in updating the any database table by using one function module only by giving the table name and fileds of that table as input.
please help me in this case.

Hi Mukka,
We could update a table from the function module.
But take care that we should be locking and unlocking the object before and after updating respectively.

Regarding Error in Function Module in Update Task

Hi All,
If a function module is called in Update Task and there is some error generated from it, it comes as an exit message unlike in a normal function module.
Is there any possible way to avoid such an exit message?
Thanks in advance.
Regards,
Garima

Hi,
The problem is I am updating Z tables in a function and also calling a function in Update task to update a different set of tables.
Now, if for some reason there is an error in Update Function module, then my requirement is that rather than throwing an Exit message (which it is presently doing) the errors coming from the function should be captured so that the user knows what was wrong with the data he entered.
Is there any work around to the above requirement? Either all the tables should be updated or none of them should be updated.
Regards,
Garima Thapar.

Additional Qty calculation during Ticket creation using function modules

HI,
I am trying to create and actualize ticket using FMs in following seuence:
1) OIJB_TICKET_DEFAULTING
2) OIJ_EL_A_TICKETS_MAINTAIN_N
3) OIJB_GENERATE_DOCUMENTS_N
I am passing OIJ_EL_TKT_I_O1 details to FM OIJB_TICKET_DEFAULTING.
Requiement is based on OIJ_EL_TKT_I_O1, it should calculate additional quantities OIJ_EL_TKT_I_O2.
But it seems it is not populating OIJ_EL_TKT_I_O2.
Any Idea why FM does not calculate OIJ_EL_TKT_I_O2? Or do we need to calculate externally and then Pass it to FM? Which FM does this?
Thanks & Regards,
Umesh

Hi Umesh,
The function module OIJB_TICKET_DEFAULTING should do the conversion based on the parameters you pass via OIJ_EL_TKT_I_O1.
It will do this only if the parameter ET_TICKET_ITEM_O2 is requested.
Check if you are properly passing an internal table in this field.
Best Regards
Vishnu

Regarding the RFC Function Module call from PI

Hi All,
I am working on one File to RFC interface, in which File adapter picks the file, this file data has to goto 2 function modules in SAP system. For this i added 2 Inbound interfaces in INTERFACE DETERMINATION and I developed 2 RECEIVER AGREEMENTS. In 2 RECEIVER AGREEMENTS i added single receiver RFC Communication Channel.
Now i want assurance that once 1 st function module will execute completely, then only my second function module should be called. Is there any setting that i can do to make this sync?????.
what is the use of Send 'Confirm Transaction' in receiver RFC Communication Channel under Adavanced Mode.
Thanks,
Balu

Hi,
As per you requirement I would suggest to change your scenario as File To Proxy. It will much more easier and 100% sure to process second BAPI only after first gets successful inside the proxy.
Pass the data from file adapter to inbound proxy and then inside proxy code you first call the first BAPI and use commit wrok. Once commit work is successful then you call the second BAPI otherwise rollback the changes.
Example:
Call First_BAPI
<pass the data to it's import export parameters>
Commit work.
if sy-subrc =0.
Call Second_BAPI.
<pass the data to it's import export parameters>
Commit work.
endif.
Note: If you are not very much comfortable with ABAP the discuss this with your ABAP team mate.

Sarvesh

Regarding the obsolute function modules

Hi All,
below function module are obsolute in 4.6c ,what are the new function modules in ECC 6.0.
1.GRAPH_RECEIVE
2.GRAPH_SET_CUA_STATUS
already i search in sdn but i didnt get exact answer................
plz help me.....
Regards,
Madhu

Hi
Though these function modules are set to obsolete,they are still maintained and supported by SAP and can be used in your application further. They are set as obsolete in order to avoid the usage in new development projects. When starting new developments it is recommended to use class 'cl_gui_chart_engine' .
Hope this is helpful.

Task creation using function module

Dear Experts,
Im new to workflow.
I want to use a function module for defining a task.
i created a function module and declared the structures
ACTOR_TAB LIKE SWHACTOR
AC_CONTAINER LIKE SWCONT with in the function module
In the transaction PFAC i given the abbrname, name and category as Agent Determination: Function to be executed and the function module name
when i click on save im getting the error
Function module ZBAPI_PLANT_ADDR does not meet the workflow convention
kindly guide me to solve this issue
Regards
Arun.P

I created an extremely simple FM for role res.
FM: "Y_TEST"

ACTOR_TAB LIKE SWHACTOR
AC_CONTAINER LIKE SWCONT
Source:
BREAK-POINT ID zwf.
actor_tab-otype = 'US'.
actor_tab-objid = 'SAMPLRL'.
APPEND actor_tab.
created a simple role in PFAC using this Y_TEST FM and same cat as you used.
Works fine with bare min.
Would need to know a little more of what you are doing in the FM to assist.

Regarding certification in functional modules.

Like teched is anything for functional consultant to get certified.By taking only certification exams.
Or any other way to get certification in functional modules without studying in seimens or geneovate.By taking only certification exams.
I having SAP experience of 2years in cmm level 5 company.
Pl guide me to get certification.
Regards
Umapathy.M

Personally I felt CRM Sales 5.0 certification was quite easy and I think one can clear certification in this module without going through training academy at the above mentioned institutes. I have attended the academy for the above certification but I prepared for the exam properly only for 3 to 5 days and that was sufficient.
However, if you plan to go for certification without attending the academy then as far as I know your project manager or company needs to provide an experience letter stating you have 2 years of working experience in your stream of SAP for which you wish to write the exam. If your company provides you the experience letter then you can go for certification without attending the academy.
I am planning to go for another certification before the end of this year, may be CRM Webclient or CRM Services and i know i can go for it directly without attendin the academy.
Hope this helps!
Cheers!
AR!
