Debugging Fast Formula when logs are not generating

There are multiple processes in HCM which generates log through which we can easily traverse our FF code. Examples - Quick Pay, Accrual Run and many others.

But there are cases which does not generate logs, and it becomes very difficult to debug and traverse our FF code. Examples are - Checklist FF, Compensation Default and Validation FF and many others.

Below snippet if we will add to our FF, it will create log which can be accessed through SQL query, making it easy for us to track how FF is processing :

seq = 1
l = add_rlog(-123456, seq, 'This is my message')
seq =seq + 1

We can go into BI and query the log rows with below SQL :

select log_text from HWM_RULE_FF_WORK_LOG where ffs_id = -123456 order by log_id, rule_id
