When you write data to SAP BW, you can configure dynamic partitioning to optimize the mapping performance.
When you configure dynamic partitioning, the Data Integration Service determines the number of partitions that it must create at run time. It scales the number of partitions based on factors such as the maximum parallelism value defined for the Data Integration Service and the mapping, and the number of CPUs available on the nodes where the mappings run.
For more information about configuring the maximum parallelism value, see the
