Hi everyone,
I am working through a Territory Model project and came across a really weird issue and I was wondering if anyone else in the community has a reason for why the error message came up.

In the calculation itself, I am using a lookup function to bring in data from a calculation module to a data module but for some reason I get the error code above. I believe there is something going on with the naming convention and how it is being referenced? I managed to figure out a fix by doing the below, but was wondering if anyone knew why Anaplan is saying that the referenced line item is not being recognized properly.
Solution: Changing the line item naming convention to something like "test", then after the calc references it I changed the line item back to what it originally is supposed to be
