-20: Duplicate key Locate the document in the library structure

Explanation:

There is already a table row with the key to be inserted.

User Action:

Check whether the existing table row contains the desired values. If this is not the case, check whether values in the existing table row can be replaced with the desired values. If a new table row must be inserted, change the value of the key to be inserted in the SQL statement in order to prevent key collisions.
