TM1 IDE — The Complete IDE for IBM Planning Analytics / TM1

Author: flameY3T1

Turn VS Code into a full TM1 development environment. Write TI processes and rules with real autocomplete and a server-backed compile check, edit cubes and dimensions visually, run MDX, trace call graphs, test processes without touching your data, and mirror everything to Git — from one tree, across as many servers as you like.

What you get

• TI process editor — 4-section Monaco editor, live linter and server compile-check on save (bad code never lands), Rename Symbol, Find References, call-graph, resolver tab.
• Rule editor — context-aware autocomplete ([→dims, DB(...)→cubes/elements, !Dim→vars), CheckRules on save, Qualify Elements.
• Cube Viewer — drag-and-drop pivot, write-back, spreading, suppress zero, save views, paged loading for huge cubes.
• Dimension Editor — drag-and-drop hierarchies, multi-edit attributes, usage-check before delete.
• MDX Runner — F5 to run, autocomplete, live validation, pivoted results, history, cell-limit guard.
• Configurable linter + formatter — per-server rule sets and severity. Strict on Prod, relaxed on Sandbox.
• TI test framework (beta — use at your own risk) — record-and-replay tests that run against a clone, so your cubes stay untouched.
• Threads, Message Log, Security Manager, Chore Manager — live ops from the tree.
• Git mirror — processes and rules as files, drift detection, Pull / Push / Diff. Server stays source of truth.

Getting started

1. Install — Extensions (Ctrl+Shift+X) → search "TM1 IDE" → Install → fully restart the IDE.
2. Add a server — click the TM1 Explorer icon → Add Server. A guided quick-pick walks every field (name, URL, auth, user, password, SSL). Passwords go to the OS keychain (VS Code SecretStorage), never plain text.
3. Browse — connected servers show Cubes, Dimensions, Processes, Chores, Views, plus Files, Threads, Message Log, MDX Runner. Hold multiple connections open at once.

Click any process or rule → it opens in a Monaco editor. Edit, Ctrl+S, and TM1 IDE compiles it on the server first — on error nothing is saved, you get a red banner and a line marker.

⚠️ The TI test framework is beta — just a little experiment. It clones and rewrites your process to redirect writes, then runs it. A fun gimmick, not a production tool: try it on a Dev/Sandbox server first — use at your own risk.

Shortcuts

Debugging a process needs EnableTIDebugging=T on the server.

Security & privacy

Built for corporate environments:

• No telemetry — nothing leaves your machine.
• Credentials in the OS keychain — never in plain text or config files.
• Direct connection only — your machine straight to your TM1 servers. No third-party endpoints.
• Per-profile SSL — disable self-signed verification only on trusted networks.
• Disabled in Restricted Mode — because it can deploy and run TI code. Mark the folder Trusted to use it.
• Remote-ready — runs as a workspace extension (Remote-SSH / WSL).

Thanks to the best TM1 community in the world — at Deutsche Bahn — for the inspiration, and for finding the bugs. This exists because of you.

And a tip of the hat to linti, the inspiration behind this extension's linter. 😉
