I’ve got the error ‘object was open’. How to fix it?

These free steps will help you to overcome the error.

1. Try to increase query timeout in the ‘Remote server connections’ property.

2. One more advice on how to resolve this issue in synchronizing tools is using the 'Quantization' option. As the chances of errors occurring are higher in large tables, apply this feature to a table that has the 'object was open' error.
