SAP NetWeaver BW 7.30
Load Hierarchy Data Using 7.0 Dataflow from Any Source

Learn how to load hierarchy data using 7.0 dataflow technologies, such as transformations and Data Transfer Processes, from any source.
Key Concept

SAP has enhanced the hierarchy loading method by allowing use of 7.0 dataflow technologies. With SAP NetWeaver BW 7.30, you can load hierarchy data using transformations and Data Transfer Processes. With prior versions of SAP NetWeaver BW, you could load hierarchy data using only the direct update method of loading master data and hierarchy. This older, inflexible method uses the dated 3.x dataflow, which has limitations. 

SAP improved dataflow technology with its release of SAP NetWeaver BW 7.0. I consider this feature a key reason for upgrading from SAP NetWeaver BW 3.x to the higher version.

Version 3.x’s processes were rigid. Source system objects were tightly coupled with BW InfoProviders, and there was no separation between the persistent staging area (PSA) loads and loads to InfoProviders in most cases. SAP NetWeaver BW 7.0 enabled you to load data to the PSA independently and provided more flexibility in building and maintaining the data warehouse. However, there was still a problem: Loading hierarchies still had to be performed using old dataflow methods. SAP decided to leave out Data Transfer Process (DTP) support for hierarchy load, leaving many users disappointed. SAP listened to its customers and now has enabled hierarchy load with new dataflow technology that uses transformations and DTPs. This new technology is known as 7.0 dataflow.

Note
Dataflow technology only has two versions: 3.x and 7.0. For any SAP NetWeaver BW 7.30 system, you use dataflow 7.0 technology.

Limitations of the Old Approach

Let’s look at the major pain points of loading hierarchy data using the old 3.x dataflow in an SAP NetWeaver BW 7.0 system.

With SAP NetWeaver BW 7.0, loading hierarchy data was via the direct update method, which had the following limitations:

  • After upgrading to 7.0, you could migrate all your master data and transactional dataflows to the 7.0 dataflows, but you had to retain the hierarchy flows in the 3.x dataflow. That limitation meant you had to maintain two sets of dataflows in your system.
