Behavior:
When attempting to store a document into a File Cabinet, you receive the error:
 
"Cannot create a file when that file already exists"

Solution:
This behavior occurs when the Last_ID value of Type 1 in the FileCabinetName_IDT table does not match the highest DWDOCID from the main  FileCabinetName table. These tables would be located in the dwdata table.

***Note: Be sure to alter the FileCabinetName accordingly to match your File Cabinet table names.***

To resolve, a restore workflow must be ran to bring the database tables back in line with each other. 
Follow KBA-36290 which will instruct you on how to run a restore workflow.

Once completed, you will be able to store documents into the File Cabinet without error.
