We would suggest the customer use the newest version of either CALYPSO 2022 or CALYPSO 2023 to have the most success when importing QIF files. Older CALYPSO versions had limited compatibility with QIF files and imports often failed. The import is very reliant on how the customer is setting up their models so one must make sure they are semantically correct to have success in CALYPSO.  In all, nothing older than CALYPSO 2022 version 7.4.16.
