User receives a notice when trying to create a Landed Cost Category even though there are no other cost categories, active and inactive, with the same name.
Solution
The behavior can be caused by either of the following:
1. Standard Costing feature is disabled for the account
2. The Cost Type, Landed, is selected before typing the Name. Please ensure to type the Name first before choosing the corresponding Cost Type.
3. One-time system lapse
Usually, this is resolved after a few tries of creating the Landed Cost Category or after a short span of time after the notice is received the first time.
