In Dynamics 365 Finance & Operations (F&O), understanding where data lives behind the scenes can make a significant difference in how efficiently you work. Whether you’re collaborating with developers, configuring security, or validating data, knowing the underlying table for a field helps eliminate guesswork and speeds up problem-solving.

Fortunately, D365 F&O provides a built-in feature that makes this easy. Using form information, you can quickly identify the Data Source behind almost any field, directly from the form you’re working in.

Tip summary: Use form information to identify the table behind a field

Form information is a right-click feature that exposes metadata about a form, field, or control. One of its most valuable capabilities is showing the Data Source, which typically corresponds to the table where the field’s data is stored.

This allows users to quickly connect what they see on the screen to the underlying data structure, without needing to rely on trial and error.

Key benefits include:

• Quickly identify the table behind any form field
• Improve communication with developers on customizations
• Support security design and troubleshooting
• Enable easier data analysis and table-level validation
• Reduce guesswork when working in complex forms

When to use this tip:

This feature is especially helpful when:

• Communicating exact table and field names to developers
• Using tools like SysTableBrowser to review or validate data
• Designing or troubleshooting security permissions
• Investigating data issues or unexpected values
• Understanding how data is structured behind the user interface

Prerequisites:

• System Administrator access is required
• The field must be on a standard form (some embedded or computed fields may vary)
• The Administration section must be visible in the form information panel

Steps: How to identify the table behind a field

1. Navigate to the form that contains the field you want to investigate.
2. Right-click directly on the field (not the label, if possible).
3. Select Form information > Form name.

4. A side panel will appear on the right side of the screen.

5. Expand the Administration section (if it is collapsed).

6. Under Control information, locate the Data Source field.

The Data Source typically indicates the table where the field’s data is stored.

Tip note:

Many forms in D365 F&O pull data from multiple tables, and fields that appear simple may actually come from joined or related data sources. Without visibility into the underlying structure, it can be difficult to troubleshoot issues or communicate clearly with technical teams.

By identifying the correct table:

• Development discussions become more efficient
• Data issues can be validated more quickly
• Table-level analysis becomes significantly easier

This is especially valuable when reviewing data across all records or troubleshooting inconsistencies at scale.

Quick tips & tricks

• If the Data Source doesn’t look like a table name, the field may come from a query or joined data source
• Capture the Form Name and Menu Item Name while in form information, both are useful for security and troubleshooting
• Encourage power users to include table and field names when reporting issues to reduce back-and-forth
• This is a great technique to include in admin or super-user training

Final thoughts

Understanding where data lives in D365 F&O empowers users to work more efficiently across development, security, and data analysis tasks. Instead of guessing or relying on others to identify data sources, users can quickly access the information they need directly within the application.

This small but powerful capability improves communication, speeds up troubleshooting, and helps organizations get more value from their system.
