actually, you would need to do dbcc traceon(3605,11202,11203,11204,11205) - only problem is that it is global - the 11204 might make things easier as it would show the error message, so search for it to find the statement....you could try enabling at MYSERVER, but I would be tempted to enable on MYSERVER_REMOTE to see what it is catching.
There are CIS capabilities settings - am not sure what MYSERVER_REMOTE is set to - is it ASEnterprise or sqlserver??? Reason asking is CIS might be stripping the OR if it thinks remote can't handle it.
