Enable the debug profiles for concurrent program or API

For Concurrent Program:

FND: Debug Log Enabled YES 
FND: Debug Log Filename NULL 
FND: Debug Log Level STATEMENT   -- Unexpected, Error, Exception, Event, Procedure, Statement
FND: Debug Log Module %


SELECT log.module , log.message_text message
FROM fnd_log_messages log,
            fnd_log_transaction_context con
WHERE con.transaction_id = < request_id >
AND con.transaction_type = 'REQUEST'
AND con.transaction_context_id = log.transaction_context_id

ORDER BY log.log_sequence;


For API:

1) Execute below before API call:

fnd_global.apps_initialize(fnd_user_id, fnd_resp_id, fnd_appl_id);
fnd_profile.put('AFLOG_ENABLED', 'Y');
fnd_profile.put('AFLOG_MODULE', '%');
fnd_profile.put('AFLOG_LEVEL','1'); -- Level 1 is Statement Level

fnd_log_repository.init;

2) Find the current max log sequence value

SELECT MAX(LOG_SEQUENCE)

FROM FND_LOG_MESSAGES;

3) Call API

4) Execute below after API call:

fnd_global.apps_initialize(fnd_user_id, fnd_resp_id, fnd_appl_id);
fnd_profile.put('AFLOG_ENABLED', 'N');
fnd_profile.put('AFLOG_MODULE', '%');
fnd_profile.put('AFLOG_LEVEL','1'); -- Level 1 is Statement Level

fnd_log_repository.init;

5) Run the below query 

SELECT module, message_text

FROM fnd_log_messages

WHERE log_sequence > &max_log_from_step2

ORDER BY log_sequence;

Query to find the current running sql query of the concurrent program

select hash_value,sql_text
from v$sqltext
where hash_value in (select vs.sql_hash_value
                    from v$session vs
                    where vs.module like '%CONC_PRGO_SHORT_NAME%')
order by hash_value,piece;
