There are a few possible causes of this error.
1. The Dynamics GP User ID does not have correct SQL permissions to access the table. See this link for more information:
2. The table is a temp table that no longer exists. Does the error message look like this?
Invalid object name '##0100819'
If so, it is a SQL temp table. If GP has been open for a long time it may have lost its connection to the SQL server and it cannot find the table. Or, the SQL server may have been restarted and the temp tables were dropped. Or a network issue has caused GP to lose its connection. Try restarting your Dynamics GP client. If the issue persists with similar errors, please contact WilloWare Support.
3. The table if a physical table that does not exist. Does the error message look like this?
Invalid object name 'W6992Setup'
Compare this table name to a temp table name, such as ##0100819. Temp tables are prefixed with ## but physical tables are not. A common cause of this is that the WilloWare product installation has not been run. Please see the link below for instructions on re-running the installation:
