What is left out on purpose?

Opening and closing models, bulk deletes, the calendar and version switchover, deleting files and user administration. Uploading an import file only fills the file: nothing is imported until the import that reads it runs.

Why does Anaplan refuse to show cells or change data?

Anaplan only lets a Workspace Administrator of that workspace read cells and change data through its API. Ask an Anaplan administrator for that role.

How much can it read or write at once?

A view comes back as up to 2,000 lines per call, and Anaplan refuses views over a million cells, so narrow the page or pick a smaller view. One write changes up to 10,000 cells.

Does ChatGPT see the password or key for Anaplan?

No. You sign in to Anaplan through Flowplane, which keeps that sign-in sealed. ChatGPT only gets a Flowplane sign-in for you, which you can revoke in the console.

Can ChatGPT change things in Anaplan without asking?

Not by default: every change in Anaplan waits for your approval in the browser. Your workspace’s rules decide, per tool.

Connect ChatGPT to Anaplan

ChatGPT reaches Anaplan through one Flowplane address. You add Anaplan once in Flowplane, add that address to ChatGPT, and sign in. Walk your Anaplan models, read views as tables, and write cells, change lists or run imports and processes after your approval by default.

Add Anaplan in Flowplane
In the Flowplane console, add Anaplan, choose your Anaplan environment (Global or your own region), paste the OAuth client ID and secret, and sign in with Anaplan.
Your Anaplan tenant security administrator registers an OAuth client in Anaplan once (Administration, Security, OAuth clients, type Authorization code grant, with the callback URL the Flowplane console shows and a rotatable refresh token). You paste its client ID and secret into Flowplane, and then each person signs in with their own Anaplan account, so the assistant acts as them. Flowplane keeps the secret and the login sealed; the assistant never sees them.

What it can do

What ChatGPT can do in Anaplan

Anaplan holds the planning models of finance, sales and supply chain teams. Through Flowplane an AI assistant can walk a model, its modules, line items, views, lists and versions, read a view’s cells as a table, and see which imports, exports and processes exist and how a run is going. It can also write cells, add, change or delete list items, upload an import file and run an action; those wait for your approval by default.

On ChatGPT Pro the connection only reads: write cells, add list items, update list items, delete list items, run an import, export or process, upload a file are not offered there.
