- AMOUNT(S$) => At last, it will calculate Total Amount in $
- % OF AMOUNT
- CUML OF Total amount
- NO OF PO
- NO OF ITEMS
 TOTAL: 0.00 0
Function module is used to convert the amount from Singapore$ to local curreny.
(Suppose, total amount is S$100, and u r calculating for US, FM will convert the S$100 into corresponding value in US$ or
Let us take India - For India, say S$1 = INR 27, then say the supplier from India, quotes Rs. 2700, it will then be converted and shown as S$27)
Hope this will be useful to understand

I need to know thelist of bapi's and function modules used for transaction

I need to know thelist of bapi's and function modules used for transaction in order to use these FM or BAPI in reading some fields of equipment master and functional loocation.Can any one suggest me some methods...or do i need to write a report for the same.

Steps to find the BAPI/function modules used in a transaction
1) Find the package of the transaction thro' SE93.
For example the package for the transaction VA03 is VA
2) Go to Se80, key-in the package (say VA)
3) You can see the function modules under the folder finction group and
you can see the BAPI's under the folder Business Engineering-> Business Objects-> double click on the released methods of the Business Objects

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.

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 .

What are function modules used in alv,and its explanation

what are function modules used in alv,and its explanation

hi..
The important function modules are
Reuse_alv_fieldcatalog_merge
Reuse_alv_list_display
Reuse_alv_events_get
Reuse_alv_grid_display
Reuse_alv_commentary_write.
REUSE_ALV_FIELDCATALOG_MERGE
 This function module is used to populate a field catalog which is essential to display the data in ALV.
 If the output data is from a single dictionary table and all the columns are selected, then we need not exclusively create the field catalog. Its enough to mention the table name as a parameter (I_structure_name) in the REUSE_ALV_LIST_DISPLAY. But in other cases we need to create it.
Note : Fieldcatalog can be filled manually also by filling up all the required details into the internal table
The important parameters are:
 1. Export:
 a. I_program_name : report id
 b. I_internal_tabname : the internal output table
 c. I_inclname : include or the report name where all
 the dynamic forms are handled.
 2. Changing
 ct_fieldcat : an internal table with the type
 SLIS_T_FIELDCAT_ALV which is declared in the
 type pool SLIS.
REUSE_ALV_LIST_DISPLAY
This is the function module which prints the data.
The important parameters are:
1. Export:
 I_callback_program : report id
 I_bypassing_buffer : X
 I_buffer_active :
 I_callback_pf_status_set : routine where a user can set
 his own pf status or change the
 functionality of the existing pf status.
 I_callback_user_command : routine where the function codes are
 handled.
 I_structure name : name of the dictionary table
 Is_Layout : structure to set the layout of the report
 It_fieldcat : internal table with the list of all fields and their
 attributes which are to be printed (this table
 can be populated automatically by the function
 REUSE_ALV_FIELDCATALOG_MERGE
 It_events : internal table with a list of all possible events
 of ALV and their corresponding form names.
2. Tables:
 a. t_outtab : internal table with the data to be output
REUSE_ALV_EVENTS_GET: 
 Returns table of possible events for a a list type
1. Import:
 Et_Events :
 The event table is returned with all possible CALLBACK events for the specified list type (column NAME). For events to be processed by the Callback, their FORM field must be filled. If the field is initialized, the event is ignored. The entry can be read from the event table, the field FORM filled and the entry modified using constants from the type pool SLIS.
2. Export:
 I_list_type:
 0 = simple list REUSE_ALV_LIST_DISPLAY
 1 = hierarchical-sequential list
 REUSE_ALV_HIERSEQ_LIST_DISPLAY
 2 = simple block list REUSE_ALV_BLOCK_LIST_APPEND
 3 = hierarchical-sequential block list
 REUSE_ALV_BLOCK_LIST_HS_APPEND
REUSE_ALV_GRID_DISPLAY
A new function from 4.6 version, to display the results in grid rather than a
preview.
Parameters : same as reuse_alv_list_display
REUSE_ALV_COMMENTARY_WRITE
This is used in the Top-of-page event to print the headings and other
comments for the list.
It_list_commentary : Internal table with the headings of the type
 slis_t_listheader.
 This internal table has three fields:
 Typ : H - header, S - selection, A - action
 Key : only when typ is S.
 Info : the text to be printed
plz reward pts if helpful.

vijay.

Calling a report from function module

Hi Friends,
I have requirement for Function Module i.e. we will add the button to the standard T-code and ( Function added in config ) then
Function to be called from Customizing
Program A called from customizing function
CalculationPDFFunction is called from program A.
So can any one help me the logic for "calling a report from function module ".
Thanks in Advance.
Regards,
OSReddy.
Edited by: OSReddy on Sep 23, 2011 7:31 AM

Hi Jaya,
Yes. It is possible to call ur custom program using SUBMIT statement.
1. If u have data to pass then build table type RSPARAMS and use below statement.
data:
      rspar_tab TYPE TABLE OF rsparams,
      rspar_line LIKE LINE OF rspar_tab,
SUBMIT report1 WITH SELECTION-TABLE rspar_tab
               AND RETURN.
1. If u want to create variant to the program and use that. use the below statement .
SUBMIT report1 USING SELECTION-SET 'VAR1' "variant
               AND RETURN.

Call report in function module

Hi All,
Please tell me how to call report in function module. i want input parameters of function module with same selection screen parameters of report. please tell to me .if possible provide the code.
Thanks,
Raju.

Hi Kumar,
Incorporate the below logic in the FM that you have developed.
SUBMIT zreport WITH s_vbeln IN t_saleorder_range
WITH p_file EQ w_file
AND RETURN.
Note: Here, t_salerder_range is an internal table of type range. It has four fields just like selection-options...SIGN,OPTION, LOW and HIGH. Whatever the values that you pass here would be taken as the selection screen values for the report that you are calling.
Hope this is helpful

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.

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.
Regards,
Aditya

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

Plz hlp me in understanding thz report and function modules used in it
