Do our entities have to change their own chart of accounts?+
No. Each entity keeps its local accounts and dimensions in its own accounting system. The group structure sits in Control, and mappings connect the two without renaming or rebuilding the source systems.
What happens when an entity adds a new account?+
It arrives as a local account after the next sync and stays outside the group structure until it is mapped. With AI automapping on, Control posts one shared proposal when the mapping needs new group accounts, and the workspace reviews it.
Does editing a statement layout change the numbers underneath?+
No. A layout decides where a group account appears and how rows and formulas calculate. It does not change account mappings or source transactions. Changing a mapping, by contrast, can change values in every report that uses that group account.
Can an AI client read the group structure?+
Yes. Claude, ChatGPT, Codex and other MCP clients can read group accounts, dimensions and statement layouts over MCP, next to the statements built on them. Each user’s Control permissions still apply.
