Upgrade 2017- Sync Issue while doing data upgrade

Hi All,

we are doing data upgrade from 2016 - 2017, After the upgrade, we have deleted the Table : Object Manager objects from the Db using Force sync Mode. The Objects were deleted successfully. Now while coming any table in the object we are facing the below issue.

---

Microsoft Dynamics NAV Development Environment

---

The following SQL Server error or errors occurred when accessing the Object table:

208,"42S02",[Microsoft][SQL Server Native Client 11.0][SQL Server]Invalid object name 'OM - Setup'.

SQL:
UPDATE [TEST2017-UPGRADE].[dbo].[Object] SET [BLOB Reference]= NULL WHERE ([Type]=1 AND [Company Name]='' AND [ID]=9183) AND ([timestamp]<=0x0000000004A95A7B)

---

OK

---

we have checked in Object Metadata Snapshot table also but, we didn't see any records for this table.

after that, we tried to import back all the objects which were deleted. System is not allowing them to import. And it is showing the same error.

please suggest..

Regards,
Teja. G
