How to Dynamically Assign Data based on Selection in a Planning Model

How to create a planning model where users can enter and select variables in one location and TM1 then assigns the data dynamically to all required dimensions.

Feeding from a Consolidation to a Leaf Element in TM1

How, in TM1/Planning Analytics, to feed from a consolidated element in one cube to a leaf element in another cube using a single consolidation feeder with a worked example.

Persistent Feeders in TM1 – Explanation and Implementation

Persistent Feeders can dramatically decrease the time required to restart a TM1 model. Here is an explanation of what Persistent Feeders are and instructions on how to implement them in your TM1 model.

Over Feeding in TM1 – What is it and How to Avoid it

Overfeeding is where TM1 feeders are targetting more cells than are required. This can lead to excess memory consumption and reduce performance. Here we explain over feeding and how to avoid it.

What is Skipcheck in TM1?

Skipcheck in TM1 forces the TM1 engine to “skip the checking” of empty cells in a cube. So if you had 30 days in a month and data in only 9 of them, only 9 cells would be aggregated to get the total for the month. With the the skipping of blank cells disabled, all 30 cells would be checked to get the month total – three times more inefficient. … Continue Reading

CubeProcessFeeders – Forcing TM1 to Reprocess Feeders

In the rules for many cubes we work with there are conditional feeders. These often cause us problems where the evaluated value changes from a zero to a non-zero value and the fed cell does not get initiated and therefore the rule does not calculate. Background on Feeders As you would undoubtedly be aware, TM1 is an in memory application and extremely efficient with utilising that memory. It is also … Continue Reading

First TM1 Feeder!

So I just added my first ever Feeder in TM1.  Woah, that was confusing.  But I’ll get over it and it worked first go!  Let me explain. I have a cube, Opex, that is to be used in a rolling forecast model for forecasting Operating Expenses.  I have a Scenario dimension with Actual and Current Forecast in it (amongst others).  I have a TI script that is loading Actual values … Continue Reading

Conditional Feeders

Conditional feeders can be used to minimise the storage impact of rule feeders. This post goes through the various ways to utilise conditional feeders and workaround to issues that can arise implementing them.
