Found the solution
In file Dataaccesslayer.sqlclient/StoredProceduresXml.cst
I've added to the if (IncludeGetList) section:
<%if (ActiveCol != null){%>
WHERE
Active = 1
<%}%>
And above in the
// Holds the ActiveCol column if there's any
ColumnSchema ActiveCol = null;
foreach (ColumnSchema column in cols)
{
if ( ! IsIdentityColumn(column) && ! IsComputed(column) )
colsUpdatable.Add(column);
if (column.NativeType.ToLower() == "timestamp")
RowVersion = column;
if (column.Name.ToLower() == "active" && column.NativeType.ToLower() == "bit")
ActiveCol = column;
}
