Just for your update, i checked my profile option "User Type" for the responsibility Inventory and found that it was set to HR. I removed this option, and tried again to sign in as Inventory responsibility. The error this time has changed (see attached). What do i set the "User Type" profile option to for Inventory responsibility so that i can navigate to the organization menu. Eliminating this problem one by one is highly appreciated and your involvement is priceless. Thanks.
