Standard Macro and Functional Module in HR -Programming.

Hi friends,
Could i know the difference between a standard macro and a function module in hr programming.
how do we have to use that and what are the different std macro's and functional modules used in HR-Programming...
Thanks in Advance..
Regards
Shiva

You will find the macros in table TRMAC .
Macros are set of pre defined instructions .
You can define your own macros in the program using 'definition' command or use standard macros.
you will find most of the HR function module starting with HR* or RH * .
You can get Macro definition / its fundamental difference with function module on web .

Diff b/w BAPI and Function Module.

What is the difference between BAPI and Function Module....
By Interface programming do we mean posting data thru BAPI,BDC....

Hi Alex,
BAPI: Standard Interface in the R/3 system that allows the system to communicate with components of other business suites.
FM: These are the procedures that are defined in the Function Groups and can be called from any ABAP Program. FM allow you to encapsulate and reuse global functions int he R/3 system.
The main basic difference between BAPI and FM are
1) All BAPIs are FM but not all FMs are BAPIs
2) BAPIs are remote enabled
3) BAPIs interface will not have a changing and exceptions. They can not be used to have use dialog.
Interface programs can post data to SAP either through a BDC, BAPI, IDOC etc. It depends on the type of requirement.
Hope this solves your question.
Enjoy SAP

Difference between bapi and function module

Can you guys tell me what are the differences in calling bapis and function modules?
I see we are calling both as the same way we call function modules. May be for bapis, we need to be careful in declaring and passing those exact structures. Can you please make it clear reg. the differences between them?
I appreciate it.
Thanks!

HI,
See these links on help.sap.com
<b>For BAPI:</b>
The data entered in the Internet is transferred to the R/3 System via BAPIs (Business Application Programming Interfaces).
Data in the R/3 System is accessed via BAPIs as well.

<b>For Function Module:</b>
The important use of functional module is it is used by Enhancements.
SAP Enhancements are used to expand the standard functionality within SAP.
Enhancements use function modules and are called from the standard SAP code.

Updating liveCache Data using Function Module or ABAP program.

Is it possible to update APO Live Cache using Function Module or ABAP Program.
Will the aggregation/disaggreagation remain the same if data is modified using Function Module or ABAP Program.

Vikas

ello Vikas,

& read about 'SAP liveCache'.
As you know objects stored in liveCache in the class containers can be accessed
and manipulated only via LCA routines which are methods of LCA objects.
The registration of the LCA routines is done automatically when
the liveCache is started by the LC10, check the lcinit.log file.
The shared procedures in the LiveCache are written in C++ and shipped
to the customers as binary shared libraries(LCA-Routines) < LCA build >
together with the LiveCache. The original C++ source code of the
libraries is not generally available to the customers.
The LCA routines could be called via "/SAPAPO/OM*" ABAP functions.
-> For SAP liveCache documentation in English:

In transaction LC10 for the LCA connection choose liveCache:Monitoring
then go to Problem Analysis -> DB Procedures=>
The system displays an overview of all database procedures loaded into
liveCache, their input and output parameters, and other details.
-> Tr. /n/SAPAPO/OM16 ( in further releases /n/sapapo/om19 ) is provided by
SAP to get information about data stored in the LiveCache. If you would
like to get your own views, you should write a special report in ABAP using

To use SubRoutines and function modules and include

Hellow Friends ,
Can any body suggest me at waht situations we have to use SubRoutines and function modules and include in an abap report and also i need the standards in an abap program.

Hi Rajesh,
You use create subroutines within your programs for those block of codes which are used often within the scope of the development. Function modules are like global subroutines , hence any number programs which might want to use the functionality within the function module can do so.
Creating includes is a good programming prctise, e.g. one for data declerations , one for subroutines, so that it makes the code more reader friendly and also helps in modularizing the program. Also once you put a subroutine in an include, you can use the same subroutine in other programs by referring to the include with the INCLUDE statement in your other programs.
Hence basically they are used for :
1. Reusability
2. Modularization of code (make it more readable)
Hope this is of some help.

Aditya

How to upload Excel file in BI using function module in abap program

How to upload Excel file in BI using function module in abap program?

Hi Anuj,
To upload the file , you can try a standard program "RSEPSFTP" .
while you execute the program , a selection screen appears in which the inputs should be give as
RFC destination - The target server name
FTP command- PUT
local file - your file name
local directory - path of your local file
remote file - your target file name
remote directory - where it has to be stored
Hope this is useful for you
Thanks & regards

Which is better Function modules or Include programs?

Hi,
I am working on an enhancement and it has lot of screens with a tree structure on the left. Now we are planning to have each screen to have its PAI/PBO and the processing logic to be in seperate include programs.
However in our team we have debate as to go in for include programs or for Function modules. The opinion here is that the program should not take long time to load if its going to be include programs.
Please suggest what approach is better, is it Function modules or include programs.
Any other suggestion is also welcome.
Thank You,
SAC.

Thank You all.
In this enhancement I have about 13 screens and has business logic in each. So if I go with each screens and business logic coding in seperate Function modules than includes under 1 function group is adviceable?
Using object oriented approach is really the best thing here, but however most of my team members are not welversed in OO concepts. The deadlines are very tight for grooming my team members as well.
My only concern is that with so much screens and business logic in 1 transaction should not bring down this programs performance when its executed.
Any other suggestions to keep in mind for this is appreciated.
Thank You.
SAC

What is the difference between subroutine and function module?

What is the difference between subroutine and function module?

Hi,
they can both return values.
FMs are mainly used when a routine is to be performed by many programs.
Subroutines (forms) are generally only executed within one program.
You can perform routines from other programs, but it's not often done.
both forms and FMs are reusable modularization units.
To distinguish we generally say that forms are used for internal modularization and
FMs are used for external modularization.
To decide on which to implement, consider whether you need the content to be used just for a limited program
or wheteher it can be called from many independent programs.
For the first purpose it is better to implement a form whereas for the second we implement an FM.
However, ABAP does not isolate the usage context.
That is; you can call a form from another program within whose code the form is not actually implemented.
However, this requires attention since the form may utilize global variables.
The same issue holds for FMs.
FMs are encapsulated in function groups and function groups may have global variables that can be globally
used by all FMs inside it.
Thanks,

The Problem is about Standard Back Button Function in the Report Program.

The Problem is about Standard Back Button Function in the Report Program.
In the Report,First call screen Then Using "write" output some information,That is ok. but In the GUI When I press back button that is standard button,it exit screen to program.
My question is how can i do When i press back button,the screen can be back forward first screen instand of exit screen to program. Thanks .

Hi,
You can define your own PF-STATUS and in that assign the function code for BACK button anything except 'BACK'.
The code would somewhat look like this:
SET PF-STATUS 'TEST'.
write : itab-col1,
itab-col2.
in the PF-STATUS 'TEST', assign the function code to BACK button as 'BCK'.
Now in your program you can use the event AT USER-COMMAND.
In this you can handle the functionality of BACK button.
Hope this helps.

Standard Remote-Enabled Function Module to display data.

Good afternoon,
Is there any Standard Remote-Enabled Function Module which can be used to display a list of material, supplier or stocks data?
First time, I was trying to use FM link to BW Extractor as MDEX_MATERIAL_MD for Material Attributes, but these kind of FM are not Remote-Enabled and not released.
My second solution is to find a Standard Remote-Enabled Function Module which can be used to display a list of material, supplier or stocks data, but I haven't it yet.
May someone help me in this?
Thanks in advance for your answers.
Best regards,
Paul d'ORIGNY

Hi,
Suppose you want to read data from the vbrk table in ECC through a function module, then you can define the function module as "remote-enabled"(attribute tab in se37-processing type). You can try the following code out:
FUNCTION Z_EM_INVOICE.
*""Local Interface:*
*" IMPORTING
*" VALUE(I_FKDAT) TYPE FKDAT OPTIONAL
*" TABLES
*" E_VBRK STRUCTURE VBRK
*select * from vbrk into table*
e_vbrk where fkdat = i_fkdat.
ENDFUNCTION.
From BI you can call the function odule as follows:Supposing that you are calling the function module in the start routine of a dso:
data : v_dest_system TYPE char255.
data: l_vbrk type table of vbrk.
v_dest_system = 'DRDCLNT010'
CALL FUNCTION 'Z_EM_INVOICE''
destination v_dest_system
EXPORTING
i_fkdat = <passing variable>
e_vbrk = l_vbrk.

Tracing Form and Function modules using SE30

Hi,
I want to trace only the Forms and function modules that are executed by a program using SE30. I have tried setting the variants in different ways but it still gives lot of junk information which i dont need. How can I set up the variant so that it only traces Forms and function modules executed by a program?
Will give points to right answer. Thanks for reading

Hi Srikrishna,
First of all create a vraian tin SE30. While creating the variant, in th Tab 'Duratn/Type' select the radio buton 'NONE'. Now execute yur program and then analyse.Select 'GROUP HIT LIST' Icon which gives Function Modules,Subroutines etc.

Function Groups and Function Modules

Hi,
Can anyone give me the detail steps for creating Function Group and then from that function group creation of function module with example?
Regards,
Chandru

Hi,
Function Group creation -
       A function group is a program that contains function modules. With each R/3 system, SAP supplies more than 5,000 pre-existing function groups.
     In total, they contain more than 30,000 function modules. If the functionality you require is not already covered by these SAP-supplied function modules, you can also create your own function groups and function modules.
      We can put all the relevant function modules under one function group and all the global variables can be declared in this FG.
FG Creation:
1)     Function group can be created in SE80. There choose the 'Function Group' from the list of objects.
2)    Then give a name for ur function group (starts with Y or Z) and press ENTER.
3)   The click 'YES' in the create object dialog box and give a short desc. for this FG and save.
Function Module:
             A function module is the last of the four main ABAP/4 modularization units. It is very similar to an external subroutine in these ways:
Both exist within an external program.
Both enable parameters to be passed and returned.
Parameters can be passed by value, by value and result, or by reference.
The major differences between function modules and external subroutines are the following:
Function modules have a special screen used for defining parameters-parameters are not defined via ABAP/4 statements.
tables work areas are not shared between the function module and the calling program.
Different syntax is used to call a function module than to call a subroutine.
Leaving a function module is accomplished via the raise statement instead of check, exit, or stop.
A function module name has a practical minimum length of three characters and a maximum length of 30 characters. Customer function modules must begin with Y_ or Z_. The name of each function module is unique within the entire R/3 system.
Defining Data within a Function Module
Data definitions within function modules are similar to those of subroutines.
Within a function module, use the data statement to define local variables that are reinitialized each time the function module is called. Use the statics statement to define local variables that are allocated the first time the function module is called. The value of a static variable is remembered between calls.
Define parameters within the function module interface to create local definitions of variables that are passed into the function module and returned from it (see the next section).
You cannot use the local statement within a function module. Instead, globalized interface parameters serve the same purpose. See the following section on defining global data to learn about local and global interface parameters.
Defining the Function Module Interface
To pass parameters to a function module, you must define a function module interface. The function module interface is the description of the parameters that are passed to and received from the function module. It is also simply known as the interface. In the remainder of this chapter, I will refer to the function module interface simply as the interface.
To define parameters, you must go to one of two parameter definition screens:
1) Import/Export Parameter Interface
2) Table Parameters/Exceptions Interface
Then in the FM interface screen, give the following
1) Import parameters
2) Export parameters
3) Changing parameters
Then give
1) Define internal table parameters
2) Document exceptions
You enter the name of the parameter in the first column and the attributes of the parameter in the remaining columns. Enter one parameter per row.
Import parameters are variables or field strings that contain values passed into the function module from the calling program. These values originate outside of the function module and they are imported into it.
Export parameters are variables or field strings that contain values returned from the function module. These values originate within the function module and they are exported out of it.
Changing parameters are variables or field strings that contain values that are passed into the function module, changed by the code within the function module, and then returned. These values originate outside the function module. They are passed into it, changed, and passed back.
Table parameters are internal tables that are passed to the function module, changed within it, and returned. The internal tables must be defined in the calling program.
An exception is a name for an error that occurs within a function module. Exceptions are described in detail in the following section.
Syntax for the call function Statement
The following is the syntax for the call function statement.
call function 'F'
    [exporting   p1 = v1 ... ]
    [importing   p2 = v2 ... ]
    [changing    p3 = v3 ... ]
    [tables      p4 = it ... ]
    [exceptions x1 = n [others = n]].
where:
F is the function module name.
p1 through p4 are parameter names defined in the function module interface.
v1 through v3 are variable or field string names defined within the calling program.
it is an internal table defined within the calling program.
n is any integer literal; n cannot be a variable.
x1 is an exception name raised within the function module.
The following points apply:
All additions are optional.
call function is a single statement. Do not place periods or commas after parameters or exception names.
The function module name must be coded in uppercase. If it is coded in lowercase, the function will not be found and a short dump will result.
Use the call function statement to transfer control to a function module and specify parameters. Figure 19.9 illustrates how parameters are passed to and received from the function module.

Function module or abap program

Hello ABAP gurus,
I need a function module or a program which can read and write into a transactional infocube. We have local currency as CAN and we wanted it to be overwritten as USD in the group currency. Here it is not a currency conversion as we are not changing the currency value but just the unit from CAN to USD. Note: No change with the transfer rules is allowed where USD can be given as a constant value. So the only option is either a function module or a ABAP program. So please any suggestion on this would be greatly appreciated.
Thanks,
anjali

Hi All,
Is there any to edit the existing code and/or parameters of an existing function module through another program.
Is there any FM known or any other technique ?
Please let me know.
Thanks in advance,
