RFC (Remote Function Call)

Function Module:-

1. Normal Function Module
2. RFC ( Remote Function Calling).
3. Update Module.
1. Start Immed.
2. Immed Start no Restarting.
3. Start delayed
4. Coll Run

Normal Function Module:

RFC(Remote Function Module):- A Remote Function call is a call to a function module running in different system . RFC allow to calls between SAP to SAP and SAP to Non SAP system.
RFC Consists of following interface.
1. A Calling interface for ABAP Program.
ABAP program can call the a remote function using the
CALL Function .........Destination Statement.
Destination parameter displays an entry in the RFCDES table (Which is defined with the transaction SM59).
2. Calling Interface for Non-SAP program
To help implement RFC partner program in non-sap Systems Sap provides the
External Interface.

Transactional RFC(tRFC) - To make the execution of RFC function more reliable , safe, and independent from the availability of the RFC server system, this is ensure that the called function module is executed only once in the RFC server system.
transaction call RFC data must store temporary in sap data base in the RFC client systems. when processing is completed this must be reported back to the calling ABAP Program.
All transactional remote function calls are stored in the tables ARFCSSTATE and ARFCSDATA.

SMARTFORMS

SMARTFORMS:-

Smartforms are the word process tool to print the business documents.
smartforms is the smartest way to work with forms.

T-code- SMARTFORMS

A forms consists of

Navigation tree
Maintenance screen
form painter

Types of Window:-

Main window:- For text and data we can defined only one main window and can place up to Main98.
main window is used to print the dynamic length data, such as purchase order , sales order.
secondary window:- We can print data in predefined output Area. fixed length data such as Company
add,vendor address.
copies window:- For print the only on the copy or only on the original. we can use system variable
SFSY-COPYCOUNT and SFSY-COPYCOUNT0.
final window:- In this window if u want to name the grand total in the letter text of an invoice. in such case we use final window.
Communication between Driver program and Smartforms
Database we retrieve the data from the database table through the driver program and linked with the smartform function module to form.

CONSTRUCTOR ( OO ABAP)

Constructor:-

A constructor is special methods used for initialize the attributes of the class.
It is special because called Implicitly whenever an object is created or whenever a class is loaded.
It never returns any values.
They are two types of constructor Instance constructor and Static constructor.

Instance Constructor:-

It's declared by using keyword 'CONSTRUCTOR'.
It's executed whenever the class is instantiated i.e whenever a new object is created.
It is object specific.
It contains only importing parameter's and exceptions.
It's executed only one'sin the life time of a Object.

Static Constructor:-

It is declared by using keyword 'CLASS-CONSTRUCTOR'.
It will executed whenever a class is loaded.
The class is loaded in two cases- (a) whenever we access the static component of the class using the class name before creating any objects (b) when we create the first object of the class.
It cannot contain any parameters and exceptions.
It is not object specific.
It is executed only one's in the life time of a class.

(Static constructor are executed first and then Instance constructor)

REPORT  ZRDD_OOPS16.

    methods constructor.  "instance const
    methods m1.  "instance normal method

  endmethod.

endclass.

data ob1 type ref to abc.
create object ob1.

call method ob1->m1.
call method ob1->m1.

data ob2 type ref to abc.
create object ob2.

   write :/ 'inside static const'.
endmethod.
endclass.

     methods m1.

    write :/ empno,ename.
  endmethod.
endclass.

  start-of-selection.
  data ob type ref to abc.
  create object ob.

  call method ob->m1.

Hierarchy of constructor execution:-

Whenever the super class as well as the subclass contains instance & static constructor's it must for sub class instance constructor to call the super class instance constructor explicitly this done by using super keyword.
This is the only place where a constructor can be or has to called explicitly .
In this case if we instantiated the sub class then first static constructor are executed from super class to subclass and then instance constructor are executed from sub class to super class.

Example 1:

REPORT  ZRDD_OOPS27.

class abc definition.
  public section.
    methods constructor.
    class-methods class_constructor.
endclass.

class abc implementation.
  method constructor.
    write :/ 'inside instance const - super class'.
  endmethod.

  method class_constructor.
      write :/ 'inside static const - super class'.
  endmethod.
endclass.

class pqr definition
      inheriting from abc.

endclass.

start-of-selection.
data ob type ref to pqr.
create object ob.

  method class_constructor.
