In the previous parts (Part 1, Part 2, Part 3, Part 4, Part 5) we focused mainly on customers either without a complete DWH or with a custom DWH solution ( Part 5). In Part 6 we looked at customers that are using SAP NetWeaver BW without SAP HANA and in this part we will look at customer that are using SAP NetWeaver BW on SAP HANA.
In our scenario we are looking at a customer that has a heterogeneous landscape, with parts being based on SAP systems such as SAP ERP or SAP CRM, parts being based on non-SAP, and parts being based on standard relational databases.
In our scenario the customer made the choice to implement SAP NetWeaver BW on SAP HANA as EDW.
In Figure 2 you can see a scenario where the customer would use SAP NetWeaver BW on SAP HANA as EDW, but without fully leveraging all the capabilities SAP BW on SAP HANA is offering. In this option the customer is just replacing the database from SAP BW with SAP HANA and does not leverage any of the new options – such as a mixed scenario.
Figure 3 shows the first option how customers could leverage some of the new capabilities with SAP NetWeaver BW on SAP HANA. In this scenario the customer not only loads the data from the source systems into SAP NetWeaver BW but instead also replicates the data from the SAP ERP system into a SAP HANA managed schema.
In the situation where the customer is using SAP NetWeaver BW on SAP HANA, there are tables in SAP HANA managed by SAP BW and you can also have tables managed by SAP HANA (using SAP HANA Studio) – as shown in Figure 3. In our example the customer replicates the data from SAP ERP in real-time to the SAP HANA system. In addition the customer is also loading unstructured information – such as Twitter feeds – into SAP HANA directly.
With the data now in SAP HANA the customer can generate a Transient Provider in SAP BW on top of the SAP HANA Analytical models and then leverage the Composite Provider capabilities and combine for example data from SAP NetWeaver BW with the information in SAP HANA without having to load the data from SAP HANA into SAP NetWeaver BW.
Figure 4 shows another example how customers can leverage the new options with SAP NetWeaver BW on SAP HANA. In our next example (Figure 4) the customer is using SAP NetWeaver BW on SAP HANA like before and also replicates the information from SAP ERP into a separate schema in SAP HANA.
In this example all the unstructured information is already stored in HADOOP and the customer is not planning on moving the data from HADOOP into SAP HANA – and he does not have to do so. With Smart Data Access from SAP HANA the customer can then point to the information in HADOOP and – as pointed out in Figure 3 – then leverage the information and combine the data with data in SAP BW.
In Figure 3 and 4 we have seen options to create a Transient Provider based on the model in SAP HANA and then to combine the data from SAP NetWeaver BW with the information in SAP HANA – a so called “mixed scenario”. Figure 5 now shows another option where our customer is generating a SAP HANA model based on information that was modeled in SAP BW. With SAP NetWeaver BW on SAP HANA customers can also leverage existing assets – such as a BEx Query or a InfoProvider – and generate an SAP HANA analytical model, which then can be accessed directly by connecting to SAP HANA.
A good example for this scenario is the usage of SAP Lumira, SAP BusinessObjects Explorer, or SAP Predictive Analysis in combination with data from SAP NetWeaver BW. In such a use case – knowing that these three BI clients can not connect to a BEx query directly – customers could use the integration of SAP NetWeaver BW on SAP HANA and generate the model in SAP HANA and connect the BI clients to the generated model.
So how about SAP NetWeaver BW on SAP HANA and SAP HANA Live ?
Figure 6 shows such a scenario. In our last example the customer is running SAP BusinessSuite on RDBMS (not on SAP HANA) in combination with SAP NetWeaver BW on SAP HANA. As mentioned previously we have two sets of schema in the SAP HANA system – one set of tables managed by SAP NetWeaver BW and one set managed by SAP HANA.
Our customer is also using SAP HANA Live as pre-configured content for operational reporting and those models are part of the SAP HANA manged content.
Our customer is loading the information from the SAP BusinessSuite into SAP NetWeaver BW – like in the prior scenarios – but is also using real-time replication to load the data from the OLTP environment into SAP HANA and uses then the pre-configured models from SAP HANA Live for operational reporting.
I hope people find this information useful and that this content helps to clarify some of the possible scenarios that are available with SAP HANA, SAP HANA Live, and SAP NetWeaver BW on SAP HANA.
In the next post we are looking at customer landscape #8, where a customer uses OLTP environments based on SAP technology and a custom DWH based on SAP products.
