Value Set Basics in Oracle Apps R12

Value Set Basics in Oracle Apps R12

1.Overview

Value-set is a group of values. It can also be thought of as a container of values. The values could be of any data type (Char, Number etc.) A value set is used in Oracle Applications to restrict the values entered by a user. For example, when submitting a concurrent program, we would like user to enter only valid values in the parameter. This is achieved by associating a value set to a concurrent program parameter. 
A Value Set is characterized by value set name and validation. There are two kinds of validations, format validation and Value validation. In the format validation, we decide the data type, length and range of the values. In the value validation, we define the valid values. 
The valid values could be defined explicitly, or could come implicitly from different source (like table, another value-set etc.) 

2. Uses 
Value-set is an important component of Oracle Applications used in defining Concurrent program parameters, Key Flex field and descriptive flex field set of values.
Some of the scenarios where value-set is used are given below:
  1. In a concurrent program, we may want users to enter only number between 1 and 100 for a particular parameter.
  2. In a concurrent program, we may want users to enter only Yes or No for a particular parameter.
  3. Suppose a concurrent program has two parameters. First parameter is department and second parameter is employee name. On selecting a particular department, we want to show only those employee names which belongs to the selected department.
  4. In a descriptive flex field enabled on a particular screen, we want to show only a designated list of values for selection by a user.
  5. In case of accounting reports, we may want users to enter a range of key flex field values (concatenated segments).
3. Steps To Create Value Set:

Navigation:
Value Set Form:

The various fields are explained below:

Value Set Name         : Any user defined unique name

Description                 : Description of the value set

List type                      : Three choices are available for this field:
·         List of Values
·         Long List of Values
·         Pop-List

Security type              : Three choices are available for this field:
        • No Security
        • Hierarchical Security
        • Non-Hierarchical Security


Format Validation

Format Type
                Possible values for this field are:
                          Char
                          Date
                          Date Time
                          Number
                          Standard Date
                          Standard Date Time
                          Time

Maximum Size        : Maximum size of the value
Precision                  : Applicable when format type is number
Numbers Only         : When this is checked, only numbers are allowed
Upper Case Only     : This is applicable when Format type is Char
Right Justify and Zero-Fill Numbers: Applicable only for Numbers
Min Value                 : Min Value allowed
Max Value                : Max Value Allowed

Value Validation

Possible values of the value validations are as follows:
 None You use a None type value set when you want to allow users to enter any value so long as that value meets the value set formatting rules. That is, the value must not exceed the maximum length you define for your value set, and it must meet any format requirements for that value set.
Independent:
When this is chosen, the individual values are defined using the navigation shown below
Values Screen Navigation:
Values Find Screen:


Dependent:

Same like Independent Value Set, except the List of Values shown to you will depend on which the Independent value you have selected in the Prior Segment. Must define your independent value set before you define the dependent value set that depends on it. Must create at least one dependent value for each independent value

In the above Value set screen, if you choose type as “DEPENDENT” and clicked the “Edit Information” Button, we get the below screen

Table:

Ø      The list of value is created based on database tables.
Ø      Allows to write simple queries, joins, order by etc
Ø      The value, meaning and ID can be used to display a value, description to the value but return ID to the calling program or screen.
Ø      Additional columns can also be displayed.
Ø      Can also create dependent values to filter LOV data based on parameter value selected earlier. This can be done using :$FLEX:.value_set_name in the where clause.
In the above Value set screen, if you choose type as “TABLE” and clicked the “Edit Information” Button, we get the below screen

 Special & Pair Value Sets:

Pair validation value set allows to select a range of concatenated Flex field segments as parameters to the report. The special value set is used to perform special validation. This is used to enter the entire key flex field segment in the single parameter of the report/calling entity.
Special and pair value sets provide a mechanism to allow a "flexfield-within-a-flexfield". These value sets are primarily used for Standard Request Submission parameters. You do not generally use these value sets for normal flex field segments.
Special and Pair value sets use special validation routines you define. For example, you can define validation routines to provide another flexfield as a value set for a single segment or to provide a range flex field as a value set for a pair of segments.
In the above Value set screen, if you choose type as “SPECIAL” and clicked the “Edit Information” Button, we get the below screen


4. FNDLOAD & Value SETS:

FNDLOAD can be used to migrate the value set information from one instance to another and below is the code sample

<-- Command to be executed -->

FNDLOAD $usrname/$Passwd
                   O Y
                   DOWNLOAD
                   $FND_TOP/patch/115/import/afffload.lct
                   file_name.ldt
                   VALUE_SET   FLEX_VALUE_SET_NAME=LEARN_VALUESET
