Application log & Assertion Faild problem

Former Member — Wed, 11 Jan 2012 15:53:53 GMT

Dear SAP community,

does SAP support writting log messages not into database but into log file?

My Problem:

I am trying to check if the bal messages would be saved in database even if an ASSERTION_FAILED occures. As you see in the report below, the function 'BAL_DB_SAVE' doesn't really save the logs directly into the database table but it waits until a COMMIT WORK is executred which means if any ASSERTION-FAILED occurs in between no BAL will be saved and I'll loose the traces of my program flow which I've written in that BAL handler.

Thank you in advance.

Here is a short report demonstrating my problem.

put the flag i_in_update_task = ' X'

this case irrespective of the assert statement it will wait for a update task to occur, when that occurs it will save the log.

if you dont pass the flag, database update will be called but not in update task and your assert statement wont let it reach the commit.

Thank you for the fast reply,

I tried to set the flag flag i_in_update_task = ' X' too but it seems that doesn't help too. the COMMIT WORK will never be executed when assertion_failed occurs.

Does anybody know an alternative to BAL ? for example writing the logs into a file instead into database?

Since this was the first search result for this issue I want to share some solutions from Application Logging in SAP Using ABAP - Code Gallery - SCN Wiki (and the comments, h/t Ben Meijs) which should work in most scenarios:

As of 731:

Use second connection parameters (2th +2th_commit) of BAL_DB_SAVE set to abap_true

Legacy handling:

Issue explicit Commit (e.g. COMMIT WORK) directly after BAL_DB_SAVE with update task parameter
Call BAL_DB_SAVE inside an RFC-Wrapper with destination NONE

Also I should note another finding: BAL_DB_LOAD only exports a handle if the log is not already loaded yet -> use parameter i_exception_if_already_loaded, catch the exception and use BAL_GLB_SEARCH_LOG to find a recently saved log which is still in memory

Hi,

I solved my problem regarding your comment. Thanks.

I used parameters (2th +2th_commit) of BAL_DB_SAVE set to abap_true.
