How to create reports using dynamic array formulas in Planning Analytics TM1
In our previous blog (https://blog.octanesolutions.com.au/what-are-dynamic-array-formulas-and-why-you-should-use-them), we discussed about Dynamic Array formulas and highlighted the key reasons and advantages to start using DA formulas.
Renaming the element name – SwapAliasWithPrincipalName
In Realtime Scenarios, sometimes we get the requirement to correct/update the Principal element name(s) in a Dimension. This would relatively be easy if the dimension is being used in one cube. In case where the dimension is used in multiple cubes, updating element name(s) without affecting the data of all the cubes, is a bit challenging. Either we export data of the cube and change the element name(s), then import the data and validate cube before and after the element change. Or deploy the Bedrock process, which requires the reboot of Instance.
Many Developers like to stay away from the topic call Feeders in TM1 / Planning Analytics world but on the other side we cannot avoid Feeders as it plays the most crucial role while Modelling the data flow.
Sometimes, dealing with Feeders may result in 2 major issues:
1. Over Feeding
- Performance issue.
- RAM consumption.
2. Under Feeding
- Totalling issue
To avoid this there is a small concept called Feeder-Less Feeding where we can avoid writing Feeders and Feeder related issues.
Feeder-Less Feeding is a Concept of Modelling the data in such a way where you write a Rule in TM1 Rule file but you don’t need to write feeders for it, still using ‘Skipchecks’ (By having the sparse consolidation algorithm on).
To show the concept of feeder-less feeding we will proceed with an example where we are computing Travel Cost with Headcount and Rate.
Travel Cost = Headcount * Travel Rate
Here we can say Headcount is the Driver of Travel Cost and if we want to feed, we would have fed the Travel Cost with Headcount.
So, element Travel Cost and Driver: Headcount should be in same dimension and Driver should be the child of its Rule Driven element as below,
The Rule element should be the Parent (Consolidation) of its Driver to get fed automatically.
Now we have inputted some filled values in the Headcount and Travel Rate.
Here we have kept the Rates in the Same Cube to keep it simple.
You can have the Rates from the same Cube as well as from another Rate Cube depends on your way of Modelling.
The simple Cube Rule we can have for current formula and the resulted Value as below.
REST stands for REpresentational State Transfer. It is web standard-based architecture and uses HTTP Protocol. TM1 REST API is a type of web service which can be used to perform create, read, update, and delete operations on TM1 objects or data. Therefore, we can maintain a TM1 model, manage TI processes, chores, dimensions and query data that is stored in the model.
This blog explains a few TM1 tasks which can be automated using AutoHotKey. For those who don't already know, AutoHotKey is open-source scripting language used for automation.

As you plan to adopt IBM Planning Analytics cloud, it’s important to understand what it takes. This blog highlights areas you will be involved-in when you upgrade from on-premise TM1 10.x.x to Planning Analytics on Cloud.
This article talks about Business Intelligence and Business Analytics, things in common and about differences between one another. This blog also talks about the paybacks for an organization once these are adopted.
