  Key Concepts: 
  Delayed update is a feature of the ABAP Runtime Environment (BC-ABA) in SAP that allows for the updating of database tables to be delayed until the end of a transaction. This feature helps to improve performance by reducing the number of database updates that need to be performed during a transaction. 
  
  How to use it: 
  Delayed update can be enabled in the ABAP Runtime Environment by setting the parameter “abap/db_update_delay” to “X”, where X is the number of seconds that should elapse before the database updates are performed. Once enabled, all database updates will be delayed until the end of the transaction. 
  
  Tips & Tricks: 
  When using delayed update, it is important to remember that any changes made to database tables during a transaction will not be visible until the transaction has been completed. This means that any queries or reports run during a transaction may not reflect any changes made during that transaction.
