MB-310 Implement Financial Management Practice Question
When defining financial dimensions, what is the purpose of the 'Use values from' field in the Financial dimension setup?
⚠ Common exam trap
Candidates often believe this field allows manual text inputs or custom lookup lists, confusing it with standard dimension value creation.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
To enable the system to pull dimension values from an existing system entity.
The 'Use values from' field allows a financial dimension to draw its valid values from an existing entity, such as 'Customers' or 'Projects'. This automation eliminates the need for manual data entry and ensures consistency across the system. By linking the dimension to a master data entity, any changes made to the master entity are automatically reflected in the dimension, reducing maintenance overhead for administrators.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To define the default ledger account for the dimension.
Why it's wrong here
Financial dimensions do not have default ledger accounts. Ledger accounts are defined in the Chart of Accounts, and dimensions are attached to them via account structures. The 'Use values from' field merely acts as a lookup source for valid dimension values.
- ✗
To create a custom dimension that is independent of any system entity.
Why it's wrong here
Custom dimensions are created by leaving the 'Use values from' field blank. Selecting an entity from the list explicitly links the dimension to an existing data source, making it a system-defined dimension rather than an independent custom dimension.
- ✓
To enable the system to pull dimension values from an existing system entity.
Why this is correct
This field maps the financial dimension to a specific data entity in Dynamics 365, such as Vendors or Projects. When this is set, the dimension values are managed by the master record, ensuring data consistency and reducing manual entry requirements for users.
- ✗
To determine which users can enter values for this dimension.
Why it's wrong here
User access to financial dimensions is controlled through Security Roles and record-level security, not through the dimension definition itself. The 'Use values from' field is purely functional for populating the list of valid dimension values from master data.
