One of our applications report

string or binary data would be truncated in table '******', column '******'. Truncated value: '******'

instead of

String or binary data would be truncated in table 'mytable', column 'mycolumn'. Truncated value: 'myvalue'.

which I get with SSMS.

What setting do I need to change to get the full message?

I've tried to search for this, but all I get is that I need to set VERBOSE_TRUNCATION_WARNINGS to ON and compatibility_level to 150. Which I've done ages ago.
