In reality it does not work for me. If I try to set summary type to formula - system tells me to enter formula first. I do that and try again:
I get the error.
The logic behind this formula is very simple. I have 2 lists with identical items, one of them is flat, with no parents. I want this formulat to take an item name from multilevel list and find corresponding element in second list (flat one). This formula makes sense for both leaf level and aggregated level items, but I can't get it to work.
If the dimension is "Account Hierarchy" and the lineitem format is "Account Hierarchy Deleveled", then the formula "FINDITEM(Account Hierarchy Deleveled, NAME(ITEM(Account Hierarchy)))" should work fine.
