From SAP:
Many SAP customers have been consolidating and transforming their data for years using SAP Business Warehouse (BW). SAP Product Manager Eric Yew walks you through end-to-end best practices with SAP Analytics Cloud integrating with SAP BW. This webinar will walk you through technical requirements and pre-requisites for data connections, technical overview on support of BW query features, best practices and tips on Story performance, BW query design, and more! A quick update on roadmap will also be provided.

Questions from customers – what is the best way to plan ahead, SP, based on upcoming roadmap features
Should start planning version upgrade as soon as possible
There are upcoming features relating to SAC with BW integration that require a baseline
If you are on BW7.5 minimum baseline will start with SP16, GA in September this year
BW/4HANA 2.0 is planned for GA end of February

SAC is more flexible with BW support with Data Import

SAP recommends HANA 2.0 – ensure compatibility
Technical overview: Data connectivity options
Source: SAP
Two different options to connect to BW
Left – live connectivity – talks to BW in best manner when understanding metadata concepts; no data replication
Data is kept safe behind firewall; data security is seamless
On right – data import – data is being replicated and stored securely in SAC – can establish a scheduling job
Use for when live connect cannot achieve such as planning or predictive use cases
Need to model in SAC and think about authorizations as the BW authorizations do not transfer

Live connectivity – talks to SAP directly

HANA calc view generated from a BW query; make sure you do a validation check on calculation view
From SAP:
There are two ways of creating SAP HANA views for BW objects: From the BW system or from SAP HANA Modeler. Although they present a number of differences, both approaches can be recommended in equal measure.
Generating SAP HANA views from the BW system is recommended if:
you mainly use the BW Enterprise Data Warehouse layer and plan to execute queries directly on the data models, without OLAP functions.
you want the SAP HANA view to be automatically adjusted when changes are made in BW
you want the SAP HANA view to be part of the BW transport system
you want SAP HANA users to be automatically assigned SAP HANA privileges
you want CompositeProviders or queries to be used for SAP HANA views
you want to access the near-line storage or use non-cumulative key figures
However, importing BW objects from the SAP HANA Modeler is recommended if:you mainly use SAP HANA Modeler and your own ETL tools
the content package can be individually configured for each object
you want to keep changes made to the generated SAP HANA view after a re-import
Technical overview: Supported BW query concepts
Source: SAP
Live connections offers the strong integration with BW query features and authorizations
Data import – BW OLAP engine is not tied to the data
Source: SAP
Metadata support for BW query concepts
Live connections understands dimensions, string, date, measures
Data import – can import into a model, but may need to do extra work in data prep so right data item is mapped
SAC does not support TIMS time concept – live connection cannot leverage it for a time series chart; data import – cannot be acquired as time concept
Source: SAP
As you can see, display and navigation attributes are supported
Live connections supports more “exotic” features, including cell editor calcuations
You cannot import a query with 2 structures; data import UI will block you from opening
Dynamic filters are supported in Live (default values in BEx Query)
Source: SAP
Variable support; pay attention to hierarchy version variables as part of prompting; SAC does not have ability to show version information in chart builder

Use can configure scaling options as shown above
Configured scaling factors in query are transferred to SAC – only happens for supported scaling options shown above
If scaling factor is unsupported, SAC will display raw number; may lead to confusion

Source: SAP
It is recommended that the SAPCP cloud connector, SAP Analytics Cloud agent, and the SAP JCO are installed together on a dedicated server, and not a personal computer. This helps to ensure that multiple users can use an import data connection without experiencing slowness or downtime. (source: SAP)

Question & Answer
| Question | Response |
| what type of queries are a source for live connection? default infoprovider query ? transient query? e.g. do I need to create a query on an infoprovider or is there a default query I can leverage? The drop down list of queries appears to include transient queries but not default queries | Live connectivity connects to the BW Queries. the Default Query on the InfoProvider is not supported. |
| lot of existing customer use SAP BusinessObjects BI, What is the positioning of SAC vis a vis BO BI? and also is there a migration path available / planned? | SAP Analytics Cloud is a pure cloud offering combining BI, Predictive, and Planning – so there is no 1-1 comparison because as part of the on-premise BI offering you don’t have such offering. Currently there is content migration planned. |
| Which datasources are available in SAC from a BW connection? for example: Infoproviders, BW queries, etc….. | SAC support BW Queries for the Live Connection. For Import BW Queries and InfoProvider are available. |
| In the case of having a calculation view created from a BW object, a connection between HANA and SAC would have to be created? Instead of using the connection between BW and SAC | Thats correct. You would then point to the SAP HANA system. |
| Is it recommended to have a Live connection and an Import connection created to the same BW system in order to support different scenarios? | It really depends on your overall requirements. For sure it is a scenario that is possible |
| 1.How much data can we import to SAC with import connection. | in a single step currently you can upload around 80.000 rows but it also depends on your backend configuration as 80.000 rows could be a large number of cells and you might have a lower number of cells configured using the safety belt in BW |
| Is there any way we can transform the dimension types when building the model in live connection? SAC is not recognising time dimension from a BW query, thus we are unable to create a time series chart. Is there any other way? | Full date dimension support is planned as part of Q1 |
| Can you do HANA modeling and create Calc views on top of SAC tables? | Are you referring to “SAC Tables” meaning the model that you created in SAC ? If so – the answer is No. |
| Will changing of measures also apply to calculations made in SAC. So, you could combine BW measures and calculations and change the order of measures? | its about changing the order or displaying measures in a table for example. its not changing the actual measure. so a calculation you created in SAC should not be impacted |
| When will the smart predict feature supported? | only working on concept for HANA Live connection; today available for import connections |
| We are working with an Analysis for Office workbook, adding data models from SAC, we are not able to consume BW and HANA models, only native models, this is going to change in the future? | that is planned for a future release |
