MI:Toolbox displays the following error message when trying to delete records.
No records have been updated Exception while committing transaction to database
If your database is set with a maximum size and you have Autogrowth disabled you may have run out of space. Check the server log file and ask your database administrator to adjust database settings if necessary. This message may also occur for other reasons.
When records are deleted a summary of that data is stored in an SQL table. If you have run out of space this summary data cannot be written and MI:Toolbox will display the above error.
Please email support if you require further assistance.
