• Key Concepts: 
  Delta Queue is a feature of SAP Business Information Warehouse (BW) that allows for the efficient transfer of data from source systems to BW. It is a queue-based system that stores data in a queue and then processes it in batches. This allows for the efficient transfer of large amounts of data without overloading the system. 
  
  How to use it: 
  To use Delta Queue, you must first configure the source system to send data to the queue. This can be done by setting up an extraction job in the source system. Once the job is configured, the data will be sent to the queue and stored until it is processed. The queue can then be monitored and managed using the BW administration tools. 
  
  Tips & Tricks: 
  When configuring an extraction job, it is important to ensure that the data is sent in batches rather than all at once. This will help to ensure that the system does not become overloaded and that the data is processed efficiently. Additionally, it is important to monitor the queue regularly to ensure that all data is being processed correctly.
