Can I use NOT IN for 2 conditions

Question

My first SQL Query was written as so,
INSERT [rscalc].[Processing_Log] (Source_nm, Log_Type,[Message],Log_dt)
SELECT '[rscalc].[usp_Validate_Generation_Map]', @Log_Type_Id, 'Source Not Found =>' + tp.Source, GETUTCDATE()
FROM [etag].[Tag_Processed] tp
WHERE tp.Source NOT IN 
(SELECT bamap.Name FROM [rscalc].[BA_Area_Source_Sink_Map] bamap
INNER JOIN [rscalc].[VER_Generation_Map] ON Area_Source_Sink_Id = bamap.Id
INNER JOIN [etag].[Endpoint_Type_Map] emap ON emap.Id = bamap.Endpoint_Type_Id
WHERE emap.Endpoint_Type = 'Source' or emap.Endpoint_Type = 'Source/Sink')
I now need to include 2 conditions,
tp.Source NOT IN and tp.Source_CA NOT IN, I came up with something along the lines of below, but I don't think this is correct?
INSERT [rscalc].[Processing_Log] (Source_nm, Log_Type,[Message],Log_dt)
SELECT '[rscalc].[usp_Validate_Generation_Map]', @Log_Type_Id, 'Source:' + tp.Source + ',Source_CA:' +                              
                        tp.Source_CA + '=>Not Found', GETUTCDATE()
FROM [etag].[Tag_Processed] tp, [rscalc].[BA_Area_Source_Sink_Map] bamap
INNER JOIN [rscalc].[BA_Areas] bareas ON bamap.BA_Area_Id = bareas.Id
INNER JOIN [rscalc].[VER_Generation_Map] ON Area_Source_Sink_Id = bamap.Id
INNER JOIN [etag].[Endpoint_Type_Map] emap ON emap.Id = bamap.Endpoint_Type_Id
WHERE  
emap.Endpoint_Type = 'Source' or 
emap.Endpoint_Type = 'Source/Sink' AND
tp.Source <> bamap.Name AND
tp.Source_CA <> bareas.ETAG_source_nm

Sometimes the best option is to try it :-)
In this case the syntax is correct but we have no way to check in practice, unless you post the DDL+DML (queries to create the relevant tables and insert some sample data). In any case those not the same queries. You changed the logic of the query
and not just add 2 conditions. Most likely the execution plan will show you differance solution.
Can you please post DDL+DML?
