Best Approach to Manage Cost Centers at Position Level in Core HR (without Financials)

Hi everyone,

We are implementing the Core HR module and evaluating the best approach to manage Cost Centers.
The requirement is to associate the Cost Center at the Position level.

In previous implementations, when the Financials module was not in scope, we created custom fields to store the Cost Center and related attributes.

Our current question is whether it is appropriate to follow the same approach — creating custom fields — considering that Financials is not active and therefore the standard Cost Center fields would not be automatically populated.

Has anyone faced a similar scenario or could share best practices on how to handle this in Core HR?
