Difference Between Update and Delta in SAP BW Data Loading Process

In the SAP BW data loading process, the main difference between Update and Delta lies in how they handle data extraction and loading.

Update: The Update process involves loading the entire dataset from the source system into the SAP BW system. This means that all records are transferred every time, leading to potentially longer loading times and higher resource consumption.

Delta: In contrast, the Delta process only transfers new or modified data records from the source system to the SAP BW system. This results in faster loading times and reduced resource usage since only the changes since the last extraction are brought over.

Therefore, choosing between Update and Delta methods in the SAP BW data loading process will depend on factors such as data volume, frequency of updates, and system performance requirements.
