Prerequisites:


Step1 : Create the Element and Element links
Step2: write the fast formula
Step3: Attach the fast formula in Formula Results

Package used to call the fast formula from the backed : ff_exec

Simple Code Snippet below: 

      l_formula_id        NUMBER;
      l_element_inputs    ff_exec.inputs_t;
      l_element_outputs   ff_exec.outputs_t;
      l_in_count          NUMBER;
      l_out_count         NUMBER;
      l_pay_value         NUMBER;

   BEGIN

      BEGIN
         SELECT formula_id
           INTO l_formula_id
           FROM ff_formulas_f
          WHERE formula_name = ‘XX_PAYROLL_FORMULA’
          AND p_effective_date BETWEEN effective_start_date  
             AND effective_end_date;
      EXCEPTION 
      WHEN OTHERS 
      THEN
      DBMS_OUTPUT.put_line (‘NO formula exists’);
      END;

      IF l_formula_id IS NOT NULL

      THEN

— Insert FND_SESSIONS row ( Optional )

  INSERT INTO fnd_sessions
             ( session_id, 
               effective_date
             )
        VALUES 
            ( USERENV (‘sessionid’), 
              p_effective_date
             );


— Initialize the formula.


ff_exec.init_formula (l_formula_id,
                      p_effective_date,
                      l_element_inputs,
                      l_element_outputs
                      );


— Loop through the Input Values

FOR l_in_count IN l_element_inputs.FIRST .. l_element_inputs.LAST
    LOOP

    —
    — Pass The each Input value name and its Value : Eg: START_DATE and p_start_date
    —    
       IF (l_element_inputs (l_in_count).NAME = ‘START_DATE’)
        THEN
           l_element_inputs (l_in_count).VALUE :=
                fnd_date.date_to_canonical (p_start_date);
        END IF;

END LOOP;


–Run The formula


ff_exec.run_formula (l_element_inputs, l_element_outputs);


— Get the Out Put Values

FOR l_out_count IN l_element_outputs.FIRST .. l_element_outputs.LAST

    LOOP
      —
      — Get all the Out Put Values Here L_PAY_VALUE is the out put value
      —
      IF (l_element_outputs (l_out_count).NAME = ‘L_PAY_VALUE’)
        THEN
           l_pay_value := l_element_outputs (l_out_count).VALUE;
      END IF;

    END LOOP;

RETURN (l_pay_value);

END;

FND MESSAGES:
Here i am Explaining  how to create Fnd Messages  via  E-Business suite  and the implementation of message retrieval via the pl/sql API package provided with Oracle Applications.
Creating an Oracle E-Business Suite Message

To create a message in the E-Business suite message library you will need the “Application Developer” responsibility.
Navigate to Application Developer > Application > Messages. This will launch a form

Enter a unique name for your message
Eg: XX_CUSTOMER_MSG
Select the language that your message is written in and the application that the message belongs
Enter the message text in the “Current Message Text” box.
Eg: This is my first message
Click the save icon.

Retrieving a message using PL/SQL:

In order to retrieve the message from the database we need to use a standard API’s in the FND_MESSAGE package.
An E-Business suite message should be retrieved as follows:
1. Clear the current session of any message variables that may already be set
2. Tell E-Business suite which message you wish to retrieve
3. Retrieve the actual message string
4. Clear the session (Optional)

Below is the PL/SQL Block to retrive the message

DECLARE
 my_message VARCHAR2(100);

 BEGIN

  –Initialize Apps Session
  fnd_global.apps_initialize( user_id      => 1234
                             ,resp_id      => 1235
                             ,resp_appl_id => 1236
                           );
                         
  /*–Note: You will get the uer_id, resp_id and Resp_appl_id using below Query
    select fnd.user_id ,
         fresp.responsibility_id,
         fresp.application_id
  from   fnd_user fnd,
         fnd_responsibility_tl fresp
  where  fnd.user_name = ‘OEAG’
  and    fresp.responsibility_name = ‘Custom HRMS Responsibility‘;
  */
 
  –Clear the existing session
  FND_MESSAGE.CLEAR;

  –Tell e business suite which message you want (custom application short name/message name) 
  FND_MESSAGE.SET_NAME(‘XXERP’,’XX_CUSTOMER_MSG’);

  –Retrieve the message
  my_message := FND_MESSAGE.GET;  

  –Output the message
  DBMS_OUTPUT.PUT_LINE(my_message);
 END;

Output for the Above Block Is : This is my first message

Using Tokens in the message:

The Oracle E-Business suite allows the substitution of tokens within a message string to enable the programmer to add dynamic content to the message at run time.
Open the E-Business Suite message create a New Message
Navigate to Application Developer > Application > Messages. This will launch a form

Enter a unique name for your message
Eg: XX_UNAME_TOKEN_MSG
Select the language that your message is written in and the application that the message belongs
Enter the message text in the “Current Message Text” box.
Eg: This is my second message and the Token User name is &USERNAME
Click the save icon.
Note: In order to insert a token into a message it is necessary to prefix the token with a ampersand e.g. &USERNAME
Retrieving message With Token Substitution
Here USERNAME is called as TOKEN, we will Add the value dynamically

Example Block  is below:

DECLARE
 my_message VARCHAR2(100);
BEGIN
 –Initialize Apps Session
 fnd_global.apps_initialize( user_id      => 1234
                            ,resp_id      => 1235
                            ,resp_appl_id => 1236
                           );
                         
  /*–Note: You will get the uer_id, resp_id and Resp_appl_id using below Query
    select fnd.user_id ,
         fresp.responsibility_id,
         fresp.application_id
  from   fnd_user fnd,
         fnd_responsibility_tl fresp
  where  fnd.user_name = ‘OEAG’
  and    fresp.responsibility_name = ‘Custom HRMS Responsibility’;
  */
 
 –Clear the existing session
 FND_MESSAGE.CLEAR;

 –Tell e business suite which message you want (Application short name/message name)
 FND_MESSAGE.SET_NAME(‘XXERP‘,’XX_UNAME_TOKEN_MSG’);

  –Set the username message token with the current applications user
 FND_MESSAGE.SET_TOKEN(‘USERNAME’,FND_GLOBAL.USER_NAME);

 –Retrieve the message
 my_message := FND_MESSAGE.GET;

 –Output the message
 DBMS_OUTPUT.PUT_LINE(my_message);
END;

Out put for above block is : 

This is my second message and the Token User name is IAMKRISHNA

Downloading and Uploading Messages using the Generic Loader

To download our example message we would use the following command at the Unix prompt on the mid-tier:
 
FNDLOAD apps/apps 0 Y DOWNLOAD $FND_TOP/patch/115/import/afmdmsg.lct XX_UNAME_TOKEN_MSG.ldt
FND_NEW_MESSAGES APPLICATION_SHORT_NAME=’PER’ MESSAGE_NAME=”XX_UNAME_TOKEN_MSG”

To Upload our example message we would use the following command at the Unix prompt on the mid-tier:

FNDLOAD apps/apps 0 Y UPLOAD $FND_TOP/patch/115/import/afmdmsg.lct XX_UNAME_TOKEN_MSG.ldt

CURSOR : A cursors is a pointer used to fetch rows from a result set 
Two types of classification s:


I.STATIC CURSOR S: 
Static : Normal cursor (implicit or explicit)

Cursor attributes  for implicit and explicit:

%FOUND – records fetched successfully
%NOTFOUND – no records fetched
%ROWCOUNT – Number of records fetched
%ISOPEN – returns TRUE if cursor is open

a. Implicit : 
Cannot be opened outside the statement
More fast and less coding effort.
Will never raise INVALID_CURSOR error
Raises NO_DATA_FOUND and TOO_MANY_ROWS exceptions (eg: select <stmt>)

Example Implicit Cursor:

select * from emp

If SQL%FOUND then

v_count:= SQL%ROWCOUNT

end if;


b. Explicit : 2 network round trips. Store data first then retrieve data. 
More programmatic control.
Programmer could open; fetch data, close, check attributes etc.

Syntax:
open c1; — cursor c1 is select <stmt>

fetch <>

exit when c1%NOTFOUND

Example Explicit cursor:

Without Using Loop s
Declare

Cursor cur1 is

select ename,empno,sal from emp

where sal<50000 and deptno=50

begin

open cur1;

fetch cur1 into v_ename,v_empno,v_sal;

exit when cur1%notfound;

—<do processing>

close cur1;

end;

Using Loops:

Declare

Cursor cur1 is

select ename,empno,sal from emp

where sal<50000 and deptno=50

begin

For rec in cur1
loop
dbms_output.put_line(‘Employee Number ‘||rec.empno);
end loop;

end;

Using Loops with Cursor Parameters:

Declare

Cursor cur1( cp_deptNo Number) 
is
select ename,empno,sal from emp
where sal<50000 and deptno=cp_deptNo

l_deptNo Number :=50;
begin

For rec in cur1(l_deptNo)
loop
dbms_output.put_line(‘Employee Number ‘||rec.empno);
end loop;

end;

II. DYNAMIC CURSOR s : 

Oracle REF CURSOR Types:
With the REF_CURSOR you can return a recordset/cursor from a stored procedure
(i.e Ref Cursors can have Record/s as return types.)
Could be declared once and defined many times in different procedures. 

a)Strong : For the strong ref cursor the returning columns with data type and length need to be known at compile time.
b)Weak :For the weak ref cursor the structure does not need to be known at compile time.

Example For the Ref Cursor :


–SPECK PACKAGE 
CREATE OR REPLACE PACKAGE REFCURSOR_PKG
 AS
  TYPE WEAK_REF_CURSOR IS REF CURSOR; — Until 9i
  TYPE STRONG_REF_CURSOR IS REF CURSOR RETURN EMP%ROWTYPE;

END REFCURSOR_PKG;

The pl/sql procedure that returns a ref-cursor looks like this:


–BODY PACKAGE 
CREATE OR REPLACE PACKAGE BODY REFCURSOR_PKG
AS
— For Weak Ref Cursor: 
PROCEDURE 
WEAK_REF_CUR_PRC( p_deptno IN number,
                  p_cursor OUT REFCURSOR_PKG.WEAK_REF_CURSOR — Until 9i
                  —- From 9i (p_cursor OUT SYS_REFCURSOR )—-
                 )
IS

BEGIN

  OPEN p_cursor FOR
  SELECT *  FROM   emp
  WHERE  deptno = p_deptno;
end WEAK_REF_CUR_PRC;

— For Strong Ref Cursor: 
PROCEDURE 
STRONG_REF_CUR_PRC( p_deptno IN number,
                    p_cursor OUT REFCURSOR_PKG.STRONG_REF_CURSOR
                  )
IS

BEGIN
  SELECT *  FROM   emp
  WHERE  deptno = p_deptno;
  end STRONG_REF_CUR_PRC;
 END REFCURSOR_PKG;
