Security consideration
Item I1 is used by formula F1, which is in turn used by formula F2. Both formula F1 and F2 are at a status 300. The current user has 0 security access to formula F1.
The user enters a search that asks for all formulas that consume Item I1 at any level and have a status 300. The search returns zero rows; it does not find F1 because of security and it does not find F2 because it did not find F1.
