If you’re working with SAP RAP, you’ve probably encountered the infamous BEHAVIOR_ILLEGAL_STATEMENT dump.
This dump could occur when the following statements are made in a RAP context:
Explicit use of COMMIT WORK or ROLLBACK WORK statements – the transaction handling and database commit is exclusively handled by RAPCalling update or enqueue functions that bypass RAP’s controlled transaction flowDirect database modifications outside of RAP’s managed approach.
Understanding the Core Challenge
The core challenge lies in RAP’s approach to transaction management. The RAP transactional model is built on the concept of Logical Unit of Work (LUW), which ensures data consistency and integrity by treating all operations within a transaction as a single, indivisible unit. It includes a late-save phase followed by a cleanup. RAP follows a controlled Logical Unit of Work (LUW) pattern with two distinct phases:
Interaction Phase: Data modifications are stored in a transactional bufferSave Sequence: Data is validated and persisted to the database
On the other hand, a COMMIT WORK statement that immediately persist changes to the database. When these two approaches collide, you get runtime errors that can halt your application.
Available Solution or Workaround
Our goal is to call our explicit commit or any other ‘Illegal statement’ in a different task. There are four ways to do that:
BGPF (Background Processing Framework)
SAP Documentation – : Background Processing Framework | SAP Help Portal
Parallel Processing
Implementation Examples :- ABAP Cloud – Parallel processing , Two Different types of Parallel Processing example… – SAP Community
Application Jobs for background Processing
Implementation Examples :- Example Implementation Using Interfaces IF_APJ_DT_EXEC_OBJECT and IF_APJ_RT_EXEC_OBJECT | SAP Help Portal ,
RFC Workaround (On-Premise Only)
We can create a wrapper RFC FM with our logic and call that using DESTINATION ‘NONE’ statement. Which will be called in a different task.
Note : This workaround are not supported by Cloud Environments.
