Select record that have part level 0 and not have map from with the table in SQL Server

How to get Part Id that have part level 0 and not have map from ?

I work on SQL server 2012 I face issue I can't get Parts that have map to and not have map from for part level 0

So Firstly I get parts that have part level 0 then secondly

if part have code type to 1273200 then it must have code type from 974451

if part have code type to 194480 then it must have code type from 7320911

So I need to display parts that have code type 1273200 for part level 0 and not have map from 974451

OR

parts that have code type 194480 for part level 0 and not have map from 7320911

 create table #codes
 (
     PartId int,
     CodeTypeId  int,
     Partlevel int
 )
 insert into #codes(PartId,CodeTypeId,Partlevel)
 values
 ---this is correct----

 (5020,7320911,1), --where map from 7320911 for part id 5020 for partlevel 0 if 1 then it is not exist
 (5020,194480,0),  --map to
   
    
  ---map from 974451 not exist for part id 7050 but not care because I need only parts have partlevel 0
 (7050,1273200,1), ---map to
 (7050,7320911,1), ---map from
 (7050,194480,1),  --map to

  ---map from 7320911 not exist for part id 8900 for partlevel 0 if part level 1 then not exist 
 (8900,7320911,1), ---map from
 (8900,194480,0),  --map to
    
  ---map from 7320911 not exist for part id 9200 for partlevel 0
