• Key Concepts: 
  Delta process is a process in SAP BW-WHM Warehouse Management that allows for the efficient transfer of data from the source system to the target system. It is used to update existing data in the target system with new data from the source system. The delta process only transfers the data that has changed since the last transfer, thus reducing the amount of data that needs to be transferred. 
  
  How to use it: 
  To use the delta process, you must first set up a delta initialization in the source system. This will create a snapshot of the data in the source system and store it in a delta queue. When new data is added to the source system, it will be compared to this snapshot and only the changed data will be transferred to the target system. 
  
  Tips & Tricks: 
  When setting up a delta initialization, it is important to ensure that all relevant fields are included in the snapshot. This will ensure that all changes are captured and transferred correctly. Additionally, it is important to regularly check and update the delta queue to ensure that all changes are being captured and transferred correctly.
