•D. Flexible Enterprise Data Warehouse Core layer: This is the layer of the layered scalable architecture (LSA++) of SAP BW/4HANA that is designed as the main storage for harmonized consistent data. The Flexible Enterprise Data Warehouse Core layer contains the Corporate Memory and the Quality & Harmonization layers, which are used to store and harmonize data from different sources and systems.

Open ODS views are used to associate an InfoObject with a characteristic hierarchy without changing the existing data flow. Open ODS views can be created on top of any source system and can be used as a source for other objects such as CompositeProviders or BW queries. Open ODS views can also leverage the LSA++ concept by using different layers such as staging, quality, and harmonization. References: 12

The delta merge process is used to transfer data modifications from the delta storage to the main storage in SAP HANA database. It can be initiated in SAP BW/4HANA in the following ways:

•By using a specific process type in a process chain, called Trigger for DB Merge. This process type can be added to a process chain and linked to the loading processes that require a delta merge. The process type allows specifying the object type and name for the delta merge.

•By using the SAP BW/4HANA data load monitor, which is a web-based tool for monitoring and managing data loads. The data load monitor has an option to trigger a database merge for an object after a successful data load.
