Suggestions for locking the value of branch-dependent cost centers

Summary:

The client where we are implementing a new company within the ERP has a particularity.

Unlike companies that are already in production today, they have a dependent relationship between the branch and cost center accounting segments.

Today, several mapping sets were mapped for accounting for other modules and integrations in Accounting HUB

We also thought about creating cross-validation rules, but this could generate future problems due to the fact that this relationship changes constantly.

The chart of accounts is the same as the one already in production, with independent characteristics for all segments. I would like any suggestions to make maintaining this relationship easier and without the risk of changing it in one place and forgetting another.
