FNRCE0043E: E_NOT_UNIQUE A uniqueness requirement has been violated.
Explanation
The server has discovered a uniqueness constraint violation. This error can occur due to a server-imposed uniqueness constraint (for example, no two class definitions can have the same SymbolicName values) or a database-imposed constraint of a unique index (for example, no folder can have contained items with the same names).
Administrator response
Check the reason for the constraint and modify the inputs so that uniqueness is preserved.
