Value Sets and Validation in EBS
Explain the different value set validation types used across flexfields, concurrent program parameters, and profile options
A Value Set defines the format, length, and validation rule for a value entered anywhere in EBS that accepts user input tied to metadata — flexfield segments, concurrent program parameters, and some profile options. Value sets are reusable, meaning a single value set like 'XX_YES_NO' can be attached to many different parameters or segments across the system.
A value set is like a dropdown menu template that a restaurant chain can reuse across every location's ordering kiosk — define 'Valid Toppings' once, and every kiosk (form/parameter) that references it automatically shows the same governed list, updated centrally.
Key Concepts
1
EBS supports several validation types: None (free text with just format/length checks), Independent (values validated against a fixed, standalone list you define), Dependent (values validated against a list that's filtered based on a related independent value, like Cities depending on selected State), Table (values validated dynamically against a query on any application table), and Special/Pair (used specifically for flexfields with complex cross-validation logic).

Table-validated value sets are especially powerful and commonly used for concurrent program parameters, since they let you write a custom SQL query (with bind variables like :$FLEX$ or :$PROFILES$ for context) to dynamically source valid values and their displayed meaning directly from application tables, keeping parameter lists always in sync with live data.

Interviewers often ask candidates to design a value set for a specific scenario (e.g., a concurrent program parameter that should list only active cost centers for the user's operating unit) to test practical, hands-on value set configuration skill, including use of :$PROFILES$.MO_OPERATING_UNIT style bind variables inside the validation SQL.
