How to create a Function Module

Hi
Please tell me the procedure to create a function module.
Thanks in advance,
Priya

Hi Srinivas,
In order to create a function module firstly you need to assign it to a function group.
In order to create function group goto t-code se37.
Choose Goto->Function groups-> Create group .
Give the function group name.
Then come back to se37 type in the name of your FM and then press <b>CREATE</b> button.

How to create RFC function module and how to call this function module

Hi,
i want to know step for creating RFC function module and then How to use this function module from some other sap system.
Thnaks,
jigar

Jigar,
To implement a remote function module in ABAP, perform the following steps:
Register the module as remotely callable in the RFC server system.
In the function module Administration screen (transaction code SE37), set the field Can be called via REMOTE CALL. Registering a module as remote causes an RFC stub to be generated for it.
Write the code for the function module.
Create the destinations.....................
Displaying, Maintaining and Testing Destinations
To display, create or modify destinations, choose Tools ® Administration ® Administration ® Network ® RFC destinations or enter transaction code SM59.
Remote Destinations are stored in table RFCDES. The RFCDES table describes logical destinations for remote function calls.
It is not possible to maintain the RFCDES table directly.
You can also access logical destinations via the Implementation Guide (IMG) by choosing Tools ® AcceleratedSAP ® Customizing ® Execute Project ® SAP Reference IMG.
In the Implementation Guide, expand the following hierarchy structure:
Basis
Application Link Enabling (ALE)
Sending and Receiving Systems
Systems in Network
Define Target Systems for RFC Calls
Displaying Destinations
The initial screen for this transaction displays a tree:
Different connection types (i.e. partner systems or programs) are possible. For further information, see Types of Destinations.
To display all information for a given destination, double-click it, or place the cursor on it and press F2 .
To search for a destination, press the Find button and specify your selection. You get a list of all entries matching your selection. Place the cursor on the one you want, and press F2 or simply double-click the destination. All information for the given entry appears.
Creating Destinations
On the destinations overview screen (transaction code SM59), the connection types and all existing destinations are displayed in a tree structure.
All available connection types are explained in Types of Destinations.
To create a new RFC destination, press the Create button. A new screen is displayed with empty fields for you to fill in.
If you want to create a new destination
As you create a remote destination, you can specify a particular application server or a group of servers for a balanced distribution of system load.
For details of the destination parameters, see Entering Destination Parameters.
Changing Existing Destinations
On the destinations overview screen (transaction code SM59), the connection types and all existing destinations are displayed in a tree structure.
You can display all information for a given destination by double-clicking it or pressing F2 on it.
To change an existing destination, double-click it, or place the cursor on it and press the Change button.
For details of the destination parameters, see Entering Destination Parameters.
Testing Destinations
To test a destination, choose the appropriate function from the Test menu.
Connection (also available via the Test connection pushbutton)
Authorization (checks logon data)
Local network (provides a list of application servers)
You can use the CALL FUNCTION statement to call remote functions, just as you would call local function modules. However, you must include an additional DESTINATION clause to define where the function should run:
CALL FUNCTION RemoteFunction
DESTINATION Dest
EXPORTING
f1 =...
f2 =...
IMPORTING
f3 =...
TABLES
t1 =...
EXCEPTIONS......
The field Dest can be either a literal or a variable: its value is a logical destination (for example, "hw1071_53") known to the local SAP System. Logical destinations are defined in the RFCDES table (or the TRFCD table in R/2 Systems) via transaction sm59 or the following menu path: Tools ® Administration, Administration ® Network ® RFC destinations. You can also access logical destinations via the Implementation Guide (IMG) by choosing Tools ® Customizing ® Enterprise IMG. In the Implementation Guide, you can then choose Cross-application components ® ALE ® Communication ® Define RFC destination.
The remote function call concept, for example, allows you to access a function module in an R/2 System from an ABAP program in an R/3 System. If you want to read a customer record from your R/2 Systems database, create a remotely callable function module in the R/2 environment which retrieves customer records. Call this function from your R/3 System using a remote function call and listing the destination for the target R/2 System:

Hi,
You can create a lock on a object of SAP thorugh transaction SE11 and enter any meaningful name start with EZ Example EZTEST_LOCK.
Use: you can see in almost all transaction when you are open an object in Change mode SAP could not allow to any other user to open the same object in change mode.
Example: in HR when we are enter a personal number in master data maintainance screen SAP can't allow to any other user to use same personal number for changes.
Technicaly:
When you create a lock object System automatically creat two function module.
1. ENQUEUE_<Lockobject name>. to insert the object in a queue.
2. DEQUEUE_<Lockobject name>. To remove the object is being queued through above FM.
You have to use these function module in your program.
Hope this will give a basic idea.

How can create a function module for currency and quantity fields

hi,
i want to create a function module with some fields.when i activated it give some errors for
netpr,menge,wemng fields(currency, quantity fields).error is it asks for reference fields.
please send me solution for it.
sreenu.

Hi Sreenu,
While creating CURRENCY/QUANTITY fields in the DataBase Table, you have to enter a REFERENCE TABLE and a REFERENCE FIELD to the field.
For that, after entering the field name and the data type in the correcponding columns, you have to place the cursor on the data type of the required field and click the CURRENCY/QUANTITY FIELDS tab. You will find two columns called REFERENCE TABLE and a REFERENCE FIELD.
you have to enter a reference table in which a currency/quantity field is used and a reference field which is a currency/quantity field in that table.
For Example, below is the table details.
FIELD DATATYPE LENGTH DEC.PLACES REF.TABLE REF.FIELD
1.SNO     CHAR 5
2.AMOUNT CURR 10     2          T001      WAERS
3.NOS     QUAN 5                 KNA1      /VSO/R_PAL_UL
Here Field 2(AMOUNT) is a CURR field whose Ref. Table is T001 and Ref. Field is WAERS and Field 3(NOS) is a QUAN field whose Ref. Table is KNA1 and Ref. Field is /VSO/R_PAL_UL.
Hope this will help you.

How two create UPDATE FUNCTION MODULE

Hi,
I have 2 tables to update one after the other...
I have geard it is advisable to use update function module for this..
can any1 tell me how to create and work with update function modules...
Answers will be rewarded....

Abhay,
How an update function module works is, the execution of the FM is delayed to until when a COMMIT WORK statement is executed.
Hence if you have the data available for updating the two DB tables at the time of calling the FM, you can pass the tables to the same FM and program the DB update for both in the same FM.
However the COMMIT WORK should be outside the FM further down in the calling program.
This link is very good and easy to follow

How to keep multiple function modules under one Web service

Hi Experts,
I have Three RFC function modules and i need to create one web service for these three RFC function modules. I know How to crearte a web service for one function module.
please suggest me How to keep multiple function modules under one Web service.
Thanks in advance
Lakshminarayana

Hi Lakshmi,
The best way to do it is to assign all the three RFC Enabled FM's to one function group. Later on the top menu in Utilities you get an option to Create a Webservice from a Function Group.
You can create one single Webservice using all the the 3 FM's.
I hope this helps.

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.
