The Execution_method_code field in the fnd_concurrent_programs table gives a single alphabet value that determines the Execution Method Code for that concurrent program type.

Note: In this example – taking the Executable Name of Autoinvoice Master Program i.e., RAXMTR

SELECT DECODE (execution_method_code,
               'X', 'FlexRpt',
               'F', 'FlexSql',
               'H', 'Host',
               'S', 'Immediate',
               'K', 'Java Concurrent Program',
               'J', 'Java Stored Procedure',
               'M', 'Multi Language Function',
               'P', 'Oracle Reports',
               'I', 'PL/SQL Stored Procedure',
               'E', 'Perl Concurrent Program',
               'B', 'Request Set Stage Function',
               'L', 'SQL*Loader',
               'Q', 'SQL*Plus',
               'R', 'SQL*Report',
               'Z', 'Shutdown Callback',
               'A', 'Spawned')
           Execution_Method
  FROM FND_EXECUTABLES
 WHERE executable_name = 'RAXMTR'; --- Concurrent Program Executable Name

The above query gives the Execution Method name for the Executable using the Execution_Method_code technically.

Also, these values are stored in the “CP_EXECUTION_METHOD_CODE” lookup. And can be derived using the query below.

SELECT lookup_code      Exection_method_code,
       meaning          execution_method,
       enabled_flag     Enabled_Flag
  FROM fnd_lookup_values
 WHERE LOOKUP_TYPE = 'CP_EXECUTION_METHOD_CODE' AND language = 'US';
