On the Summary page of the Synchronization wizard, you can click Warnings to view information about unexpected behavior that may occur when you synchronize the databases, or reasons the script may fail. The warnings are graded according to severity.

You can copy the warnings so that you can paste them into another application by clicking Copy Warnings to Clipboard.
Some of the warnings that SQL Data Compare may display are explained below.
Possible truncation error
SQL Data Compare displays this warning when the length setting of a character or binary column has changed. Data may be truncated in the synchronization SQL script.
Possible rounding error
This warning is displayed when the scale setting of a decimal or numeric column has changed. Data may be rounded in the synchronization SQL script.
Possible overflow error
This warning is displayed when the precision setting of a decimal or numeric column has changed. There may be overflows when the data is synchronized.
Conversion to XML
