Sorry that i piled things up. I appreciate your patience. As requested, i have checked the MO:Operating unit profile as well as the MO: Security profile. For the first one, my MO:Operating Unit for the Responsibility USI IC Payabales is USI IC OU, while the MO: Security profile is blank for the same responsibility. However, the Site has USI Consulting as value (see attached). As to how i was able to create the Inventory Organization, i was able to navigate through the menu without any problem initially. Guess i must have messed up on some profiles that changed things badly. Thanks so very much for your patience and help.
