After BW on HANA is already available since mid April 2012 this document was enhanched a few times since the first version.
On base of this information this "SAP First Guidance" document is released to support Basis administrators in running and and configuring a Business Warehouse on a SAP HANA system. SAP First Guidance - Business Warehouse on SAP HANA installation provides answers to major questions and issues as well as workarounds and additional details to complement standard SAP Guides and SAP notes. This SAP First Guidance document has no claim of completeness, but it is the most complete starting point for an successfull implementation.

the database migration option (DMO) is an option inside of the software update manager (SUM) for combined update and migration: update an existing SAP system to a higher software release and migrate to SAP HANA database in one technical step. As the technical SUM steps are the same, this “SAP First Guidance” document should make all customer-specific documentation obsolete. It is the complementary documentation to the existing Notes and SUM/DMO Upgrade Guides.
DMO can be used with every BW Release starting from 7.0x and onwards. It makes the two step approach (upgrade/migration) and the usage of the BW post copy automation (BW-PCA) obsolete. It can also be used within a Release, e.g. to go from 7.40 SP06 on anyDB to migrate to 7.40 SP07 on HANA.

SAP First Guidance - Implementing BW-MT for BW-aDSO
SAP BW 7.4 SP08 powered by SAP HANA is the next milestone for enterprise data warehousing with BW on HANA and provides the next level of simplification for BW .In addition, SAP BW on HANA Virtual Data Warehouse capabilities have been enhanced for even more flexibility. In midterm the advanced DSO shall replace the main BW InfoProviders with persistency (InfoCube, DSO, PSA). The classic InfoProviders are of course still supported and do co-exist with the advanced DSOs.

SAP First Guidance - SAP NLS Solution with Sybase IQ
This “SAP First Guidance” document provides all the necessary information to help quickly implement this newly released option:
Store historical BW data on an external IQ server to optimize the system size when preparing to migrate to SAP BW powered by SAP HANA.
The SAP NLS solution with Sybase IQ also helps to keep down the TCO for investing in the SAP In-Memory when historical (“frozen”) data is stored on a less sophisticated device, which acts like a “BW Accelerator on Disk”. SAP Sybase IQ is therefore the perfect smart store for this kind of data.
Please note that the SAP NLS solution can be used with all database versions supported by SAP BW 7.3x. SAP HANA is not necessary. The document is a “work in progress” and is not intended to be exhaustive. It does however contain all information required for successful implementation of the SAP-NLS solution with Sybase IQ. SAP-NLS can be used with every SAP supported database, where SAP IQ will be the seconday database for data reallocation.

Due to constant Questions about the Upgrade to NetWeaver 7.3x and 7.40 including SEM Add-On Components, we created a SAP First Guidance Document which describes the successfull Definition of a SAP BW 7.0/7.01 System with the SEM Add-On Installed on top. With this Information you will be able to integrate the stack.xml in the SUM (software update manager) process and the DMO (database migration option) DMO process included in SUM as the first input is the location of the stack.xml which defines the download directory for SUM. Furthermore the interaction of the stack.xml in the upgrade process enables you a smooth Integration into the Upgrade Process included in DMO.

The system copy procedure of SAP BW systems and landscapes is complex for a number of reasons. There is a large number of configuration settings (such as connections and delta queue handling for data loading) and system copy scenarios of SAP BW (each with different landscape aspects). These have to be handled as part of every system copy, regardless of whether the system copy is part of the migration to SAP HANA or if you want to perform regular system copies of your SAP BW landscape. BW-PCA can be used from SAP BW 7.0 onwards depending on the SPS level.
Additionally see the usage and implementation of the BW Houskeeping Task List and the Pre/Post Task Lists for Upgrade/Migration. These are Included in the database migration option (DMO) as part of the software update manager (SUM). Additional Details also can be found on the BW ALM Page.

Starting with SAP BW 7.4 SP5 on HANA a new feature to analyze data from certain perspectives, for example to calculate ABC classes or to calculate scoring classes, is introduced. This new feature is called SAP HANA Analysis Process and enables the data warehouse modeler to analyze the data using different predefined or own written functions or scripts. HANA provides the integration numerous specialized libraries like PAL, AFL, R to understand the correlation of the data in the existing EDW.
The focus of this document is the exposure of BW data natively in HANA as HANA views that point directly to the data and tables managed by BW. This enables HANA-native consumption of BW data.
This SAP first guidance document describes the handling of non-cumulative InfoCubes on SAP HANA. As the handling of Inventory InfoCubes changed within SAP BW 7.30 based on SAP HANA, this document wants to briefly describe the differences. for better understanding it is recommended to read How to Guide based on previous release How to Handle Inventory Management Scenarios in BW.
In SAP BW 7.4 SP05 on HANA the new metadata object Open ODS View is introduced, which provides the data warehouse modeler with a flexible, easy to use tool to integrate external data in the EDW Core Data Warehouse.
A CompositeProvider is an InfoProvider in which you can combine data from BW InfoProviders such as InfoObjects, DataStore Objects, SPOs and InfoCubes, or SAP HANA views such as Analytical or Calculation Views using join or union operations to make the data available for reporting. This paper explains how to create a CompositeProvider in SAP BW 7.4 SP5 using the BW modeling tools in SAP HANA Studio.
