In your Fiori Launchpad search for application :- Application Logs
Key Features
You can use this reuse library to:
- view application log details
- filter the logs by severity
- search for message texts
- display the message details
Steps Involved:-
- Create Application log Object, Subobject and External reference in ADT.
- Create Job Catalog entry.
- Create Application Job template.
- Writing code in job template class using provided interfaces- IF_APJ_DT_EXEC_OBJECT, IF_APJ_RT_EXEC_OBJECT.
- Writing code for Application Logs
- Execute Job.
Details:
Log Object, SubObject in ADT.
New Object > Others > Application Log Object.
Add your object and Subobject like below code
{
"formatVersion": "1",
"header": {
"description": "new log",
"originalLanguage": "en",
"abapLanguageVersion": "cloudDevelopment"
},
"subobjects": [
{
"name": "ZSUBOBJECT1",
"description": "Subobject 1"
}
]
}Create Job Catalog
New > Others > Application Job Catalog Entry
Here add a custom class
Application Log Catalog Entry
Create Application Job Template
New > Others > Application Job Template
Here provide your created catalog
Application Job Template
Now let's add very simple required code in the class
Interfaces: The two interfaces used are related to job execution, one gets parameters for the job other executes the code, If_oo_adt_classrun is just a reuse interface to run code as an ABAP application to debug or test.
With cl_bali_log=>create_with_header, cl_bali_header_setter=>, Provide your Object and subobject to initiate log object.
Then with cl_bali_message_setter,cl_bali_freetext_setter,cl_bali_exception_setter we have formed all type of logging type messages.
l_log->add_item, adds item to logs.
Then method save_log will write the logs in database.
it may require COMMIT WORK.
Also notice in the code we have a parameter assign_to_current_appl_job, This will attach the logs to the running Application Job itself.

This short blog can help ABAP devs create Application logs and attach it to the Application Jobs with newer approach. Also since this is a reuse logging mechanism this can leveraged in other applications as well.
Since i am also new to ABAP cloud , Expert suggestions & feedbacks are much appreciated.
If you like this blog post you can follow me for more blogs i will try to make in coming future specifically related to ABAP in cloud.
