Error Code Need Help

Dear Support

We are trying on the Asset Scanning.

Previously, we can successfully scan one of the workstation.

However, today i saw the item inside that workstation is duplicated.
4 x 1 GB become 8 x 1GB listed

So , firstly i try to rescan again to see whether it can be update,
it promoted some error where i have quickly skipped.

Then i deleted the workstation and try to rescan again.

It give me the following error

FAILURE :Database exception while discovering workstation. : Cannot delete or update a parent row: a foreign key constraint fails

Please report the problem to the system administrator, with the Error Code - 1,225,090,986,295.

Please kindly advice. Thanks

Clay
