Using $FLEX$ to create cascading dependenciesUsing $FLEX$ to create cascading dependencies

Practice 6-2 InstructionsScenarioIn this practice, you will create a descriptive flexfield that uses cascadingdependencies to validate the values entered. The flexfield will track themanufacturer, model, and color of a vehicle. The possible model values will berestricted depending on the manufacturer value, and the possible color valueswill be restricted depending on the model value.To set up the cascading dependencies, you will create table-validated value setsusing the following tables:CAR_MAKERSMANUFACTURER_ MANUFACTURER_ MANUFACTURER_NAME DESCRIPTION IDFord Ford 01Nissan Nissan 02Chevrolet Chevrolet 03Chrysler Chrysler 04

Step 1: Define Value SetsUse the Value Sets window to define three value sets.

Define a table-validated value set named XX_MFG. Give the value set adescription, a format type of Char, and a maximum size of 10. Enablesecurity for the value set.

Specify the table CAR_MAKERS as the validation table. Assign theValue column the column name MANUFACTURER_NAME, a type of



Varchar2, and a size of 10. Assign the Meaning column the column nameMANUFACTURER_DESCRIPTION, a type of Varchar2, and a size of30. Assign the ID column the column name MANUFACTURER_ID, atype of Number, and a size of 2.

Define a table-validated value set named XX_MODEL. Give the value seta description, a format type of Char, and a maximum size of 10. Enablesecurity for the value set.

Specify the table CAR_MODELS as the validation table. Assign theValue column the column name MODEL_NAME, a type of Varchar2, anda size of 10. Assign the Meaning column the column nameMODEL_DESCRIPTION, a type of Varchar2, and a size of 30. Assignthe ID column the column name MODEL_ID, a type of Number, and asize of 3. Specify the following Where/Order By clause:

WHERE MANUFACTURER_ID = :$FLEX$.XX_MFG Define a table-validated value set named XX_COLOR. Give the value set

a description, a format type of Char, and a maximum size of 10. Enablesecurity for the value set.

Specify the table CAR_COLORS as the validation table. Assign the Valuecolumn the column name COLOR_NAME, a type of Varchar2, and a sizeof 10. Assign the Meaning column the column nameCOLOR_DESCRIPTION, a type of Varchar2, and a size of 30. Assign theID column the column name COLOR_ID, a type of Number, and a size of4. Specify the following Where/Order By clause:

WHERE MODEL_ID = :$FLEX$.XX_MODELORDER BY COLOR_NAME

Step 2: Define the Structure (Segments)After defining your value sets, use the Descriptive Flexfield Segments windowto define the structure for your descriptive flexfield. For the purposes of thispractice, use the same descriptive flexfield that you worked on previously toenter your new structure. Unfreeze the flexfield definition first so that you canchange the structure.Delete the segments that you defined previously for the Global Data Elementscontext. Then define three new segments for the Global Data Elements context.

Define a segment named Manufacturer, with a prompt of Manufacturer.Assign the segment the number 10, the column ATTRIBUTE1, and thevalue set XX_MFG.

Define a segment named Model, with a prompt of Model. Assign thesegment the number 20, the column ATTRIBUTE2, and the value setXX_MODEL.

Define a segment named Color, with a prompt of Color. Assign thesegment the number 30, the column ATTRIBUTE3, and the value setXX_COLOR.

Ensure that all three segments are displayed and enabled. When you finishdefining the structure, freeze and compile your flexfield definition.



After defining your value sets and segments, navigate to your descriptiveflexfield and test the results of your work. When you are finished, exit withoutsaving.
