I have a couple of theoretical questions relating to model building.
Thanks! Any help is appreciated!
@NicolasCadierhere are the responses to your questions:
Question 1 Response:
COLLECT() is a function used in conjunction with Line Item Subsets to dimensionalize line items back to a list.
For example, in our Statistical Forecasting Application, we have a Calculation module that with line items that calculate the final forecasts for each algorithm method.
Step 1: Identify Line Items to Dimensionalize/Collect
Step 2: Create a Line Item Subset and mark line items for inclusion
Step 3: In your list, create a property called Connect to Subset whose format is your line item subset:
Step 4: Create a module dimensionalized by this Line Item Subset and relevant properties, and call COLLECT()
Step 5: Create a module dimensionalized by your list, and reference the Subset module with a Lookup from the Connect to Subset property
Another example and more details on COLLECT() can be found here: https://help.anaplan.com/anapedia/Content/Calculation_Functions/All/COLLECT.html
Question 2 Response:
Refer to Rob Marshall’s example (link below), he gave a great response and we agree with it. Create a concatenated list of the intersections and use this flat list in your model. Create a module with properties to translate the Flat List to other levels of your hierarchy

Same as Nicolas, I have a question around the Collect() function.
Sometimes, we use it to show some KPIs (line items in the original module) and the the year on year growth using the formula "Collect / Collect [LOOKUP: Prior Year] - 1" where Collect is the line item using the formula collect()
The big problem, and I haven't found a solution that is satisfactory, is that we cannot set the summary = formula when using lookup. Hence, the YY% for the full year is not accurate.
Any suggestions? We use collect because we want to show the KPIs as row and the Forecast, Prior Year and Y/Y% as columns.
@fabien.junod — Great question!
I was able to get a solution by using the OFFSET() function instead of a [LOOKUP]. This will allow you to set the Summary to Formula.
In this module view, note that the FY20 result for KPI 1 is the correct result for the year.
This blueprint view shows the formulas and summary method used for the YoY KPI.

Based on suggestions from the last AMA Pierre Kerkinni & Jon Mavetz - Model Building Solutions I've changed my hierarchy. Now when trying to build modules that roll up to site sub sets I get an error about common anscestor...which was why I built the hierarchy the way it was before. We have several hierarchies that roll up to site but don't relate to each other. Any suggestions would be appreciated. I'm pasting the new & old hierarchy below:
Old (works but is clunky):
New (get common anscestor error):
The common ancestor happens when you share the same parent. We would need some more details on why it’s necessary to dimensionalize the module with a series of lists that all share the same parent. If that is needed then it would be best to revert back to the original hierarchy so that you can have the “Applies To” include the necessary dimensions.
