When I edit the format and switch from text to list, I get the following error message: "Format of mapping used for lookup doesn't match any dimension of the source."
How do I fix this?
That error indicates that the line item which format you are attempting to change is being used / referenced by other line items, and the new format is not accepted by the formulas downstream.
If you go to the blueprint of the module where the LI is, and scroll all the way to the right, you will see the last column of the blueprint called "referenced by", which includes a list of all the modules.line items or list.properties that reference to this particular line item.
at this point you can either cut out those formulas until no other line item or property reference the one you wish to change, then change the format to list and then past back the formulas where they were. Some formulas wont work anymore and you will have to either change the format or the formula of those downstream line items
Before changing the format of any lineitem , you need to go to blueprint view of that module and check the references of that line item and copy formula of all reference line items and then remove the formulas and references and after changing the format of line item then you need to update the formula of all referenced items
Hi everyone 👋 If you build or maintain Anaplan models, you've probably hit the same walls I kept hitting. Some basic questions about a model's structure have no single screen to answer them. You end up clicking through modules and pages one by one, or writing API scripts just to get a list. These were the gaps that…

We've been building a tool called aplan4sheets and we'd genuinely like input from this community — both on what we've built so far and on what we should prioritize next. The problem we set out to solve: Anaplan's Excel add-in is Windows-centric, and there's no real native way to pivot Anaplan data in Google Sheets. We…
