Financial dimensions

This topic explains the various types of financial dimensions and how they are set up.

Use the Financial dimensions page to create financial dimensions that you can use as account segments for charts of accounts. There are two types of financial dimensions: custom dimensions and entity-backed dimensions. Custom dimensions are shared across legal entities, and the values are entered and maintained by users. For entity-backed dimensions, the values are defined somewhere else in the system, such as Customers or Stores entities. Some entity-backed dimensions are shared across legal entities, whereas other entity-backed dimensions are company-specific.

After you've created the financial dimensions, use the Financial dimension values page to assign additional properties to each financial dimension.

You can use financial dimensions to represent legal entities. You don't have to create the legal entities in Microsoft Dynamics 365 for Finance and Operations. However, financial dimensions aren’t designed to address the operational or business requirements of legal entities. The interunit accounting functionality in Finance and Operations is designed to address only the accounting entries that are created by each transaction.

Before you set up financial dimensions as legal entities, evaluate your business processes in the following areas to determine whether this setup will work for your organization:

  • Inventory
  • Sales and purchases between financial dimensions and legal entities
  • Sales tax calculation and reporting
  • Operational reporting

Here are some of the limitations:

  • You can use sales tax functionality only with legal entities, not with financial dimensions.
  • Some reports don't include financial dimensions. Therefore, to report by financial dimension, you might have to modify the reports.

Custom dimensions

To create a user-defined financial dimension, in the Use values from field, select < Custom dimension >. You can also specify an account mask to limit the amount and type of information that you can enter for dimension values. You can enter characters that remain the same for each dimension value, such as letters or a hyphen (-). You can also enter number signs (#) and ampersands (&) as placeholders for letters and numbers that will change every time that a dimension value is created. Use a number sign (#) as a placeholder for a number and an ampersand (&) as a placeholder for a letter. The field for the format mask is available only when you select < Custom dimension > in the Use values from field.


To limit the dimension value to the letters "CC" and three numbers, enter CC-### as the format mask.

Entity-backed dimensions

To create an entity-backed financial dimension, in the Use values from field, select a system-defined entity to base the financial dimension on. Financial dimension values are then created from that entity. For example, to create dimension values for projects, select Projects. A dimension value is then created for each project name. The Financial dimension values page shows the values for the entity. If those values are company-specific, the page also shows the company.

Activating dimensions

When you activate a financial dimension, the table is updated so that it includes the name of the financial dimension. Deleted dimensions are removed. You can enter dimension values before you activate a financial dimension. However, a financial dimension can't be consumed anywhere until it's activated. For example, you can't add a financial dimension to an account structure until the financial dimension has been activated. When you click Activate, all dimensions are updated and show status changes.


On the Text translation page, you can enter text for the selected financial dimension in various languages. On the Main account translation page, you can enter text for the main account in various languages.

Not all dimensions are valid for all legal entities. Additionally, some dimensions might be relevant only for a specific period. In these cases, you can use the Legal entity overrides section to specify the companies that the dimension should be suspended for, the owner, and the period when the dimension is active.

Deleting financial dimensions

To help maintain referential integrity of the data, financial dimensions can rarely be deleted. If you try to delete a financial dimension, the following criteria are evaluated:

  • Has the financial dimension been used on any posted or unposted transactions, or any type of dimension value combination?
  • Is the financial dimension used in any active account structure, advanced rule structure, or financial dimension set?
  • Is the financial dimension part of a default financial dimension integration format?
  • Has the financial dimension been set up as a default dimension?

If any of the criteria are met, you can't delete the financial dimension.
