What is the DRB designed to do?
Using the DRB, you can display linked objects or documents. Generally, these are documents resulting from a common business transaction or belonging to a common process. The DRB groups the documents together across applications. Typical accounting and logistics documents are included in the DRB. As of SAP Web Application Server Release 6.20, workflow logs and Idocs are also displayed in the DRB. All objects are connected to the DRB so as to allow access to archived data.
