LOV stands for List of Values. It looks simple, but it is one of the most important tools for controlling data quality in Teamcenter. Good LOV design reduces wrong input, improves reporting, and keeps data consistent.
Quick Summary
- LOV controls what values a property can accept
- It improves data consistency and user experience
- Main LOV types are static, dynamic, and dependent
- The wrong LOV design can create usability and performance issues
What is LOV?
LOV is a predefined set of values available for a property. Instead of free text, the user selects from controlled values.
Why do we use LOV?
- Reduce incorrect input
- Keep values standardized
- Improve reporting and filtering
- Make the UI easier for users

LOV sits between a property and the user to control which values are allowed.
Types of LOV
1. Static LOV
Static LOV contains a fixed set of values that are manually defined.
Example: Draft, Released, Obsolete
2. Dynamic LOV
Dynamic LOV gets values from a query or runtime source. It is useful when the list changes over time.
Example: Supplier list, project list, user list
3. Dependent LOV
Dependent LOV changes based on another selected value.
Example: Country → City
When to use which LOV
- Static LOV: when values are fixed and small in number
- Dynamic LOV: when values are large or frequently changing
- Dependent LOV: when value selection depends on another field
Real-world examples
- Status field → static LOV
- Supplier field → dynamic LOV
- Region and plant field → dependent LOV
Common mistakes
- Using static LOV for data that changes frequently
- Creating overly large LOV lists without filtering
- Ignoring performance impact for dynamic LOV queries
- Not validating business meaning before creating values
