I have seen that I am not the only one facing the issue that there is property or lineitem which is neither a code or name of list but it is needed for identification, like a WHERE statement in SQL.
Might it be possible to extend the FINDITEM function by an optional parameter to reference a property or lineitem which has the list as dimension.
FINDITEM(List or Time, Item to find, [Property or Line Item to use for comparison])
We have different systems connected to Anaplan which have different codes e.g. for projects and I need this feature to identify them correctly without changing the code property on every import or creating help tables with cross mappings.
