In my test system were installed all the required components for SAP Assortment Planning for Retail and I've made the settings described in
CAR 2.0 - Installation Guide and CAR 2.0 - Master Guide. I have customized replication of data from the ERP system and
configuration the DDF. Locations were replicated from ERP and displayed if we choose Fiori app "Manage location".
(see screenshot). In transaction /IWFND/ERROR_LOG errors are not displayed, also there are not dumps in backend system.
