Define a Descriptive Flexfield with None Validation

I'll be using the following DFF for this domostration.
− Descriptive Flexfield Title: Journal Categories
− Navigation Path: Setup > Journal > Categories
This practice reinforces the concept of global segments for a descriptive flexfield and demonstrates the use of the None validation type. In this scenario, you will define a descriptive flexfield to track the following information about employees:
• The person who referred the employee
• Height
• Weight
Define your Value Sets
Responsibility: System Administrator
1-(N) Application > Validation > Set. Enter the information for the first value set in the following fields:
• Value Set Name: INAM_WHO_REFER
• Description: INAM Who Refer Value Set
• Security Type: Non-Hierarchical Security
• Format Type: Char
• Maximum Size: 3
• Validation Type: Independent
Save work
2- Enter the information for the second value set in the following fields:
• Value Set Name: INAM_EMP_HEIGHT
• Description: INAM Employee Height Value Set
• Format Type: Number
• Maximum Size: 4
• Precision: 2
• Validation Type: None
Note: You cannot enable security for a value set of validation type None.

Save work.
3- Enter the information for the third value set in the following fields:
• Value Set Name: INAM_EMP_WEIGHT
• Description: INAM Employee Weight Value Set
• Format Type: Number
• Maximum Size: 3
• Precision: 0
• Min Value: 90
• Max Value: 700
• Validation Type: None
Save work.
