Source system provides cube capable delta handling with

generic strong monotone increasing delta criteria

– For example: FI DataSource 0FI_GL_11

Virtual InfoCube gives direct access to this source

Latency near-zero

Delta volume to be acquired depending on BWA load cycles

For Direct Access only, simple transformations allowed and DTP without filtering

BW query reads BWA Index and selects everything above the latest delta pointe r via

Direct Access

Prerequisite: Source system allows reporting workload
