Enable support for worksheet function DefineCalc in Websheets

In an enterprise Planning Analytic model, reports are often presented in PAW and in a structured way. I.e. there are timescales, approval hierarchies etc etc, formal processes.

In other words, it isn't users making things up on the fly.

A cornerstone of reporting are Custom reports created in Excel and then presented in Planning Analytics Workspace. The function DefineCalc allows for great flexibility when creating custom reports and avoids the need to build hierarchies and consolidations.

However, because DefineCalc is not supported in websheets this means they cannot be used for reports in Planning Analytics Workspace, which means they cannot be used in the formal reporting of many organisations, as these are presented in PAW.

This means the scope of DefineCalc is severely limited.

One of the selling points of Planning Analytics is that it can move organisations away from excel based applications, but having such a powerful function only available in Excel contradicts this message.

These limitations make DefineCalc almost next to useless in my opinion.

    Another reason why this has become increasingly important is the move towards Planning Analytics SaaS.

    For centrally authored reports, we need a way to create dynamic consolidations or custom roll-ups without permanently changing the model.

    DefineCalc provides exactly this flexibility in PAfE. However, without Websheets support, this approach cannot be carried over to PAW.

    If the traditional UDC approach is also not available in the same scenarios, the gap becomes even more significant.

    Is there currently a recommended approach for this use case in Planning Analytics SaaS?

    Hi,

    just following up on this idea as we are now in September 2026.

    In August 2025, there was still no support for DefineCalc in TM1 Web, and the public roadmap was mentioned as showing Q2 2026 for this functionality.

    Has there been any update since then? Is DefineCalc now supported in Websheets, or is this still planned for a future release?

    It would be great to get an update on the current status.

    hello,
    what is the current update for this?
    As far as I know, in 2025 it has no functionality in tm1web, isn't it?

    Moved to future consideration. Support for the DefineCalc function in Websheets will be considered for the 2024 roadmap or beyond.
