try any of these. Make sure that you have the backup of this table before running the DELETE command in case if you want to retain the data.
DELETE FROM AnotherTable 
      WHERE Part_Number IN (SELECT Part_Number 
                              FROM SAP_Table);

Open in new window

DELETE FROM AnotherTable 
      WHERE EXISTS (SELECT 1 
                      FROM SAP_Table 
                     WHERE AnotherTable.Part_Number = SAP_Table.Part_Number);
