Improve SAP BW Performance by Applying the Flat Cube

Overview SAP released the Columnstore Optimized Flat Cube over two years ago. We want to give a brief explanation of the benefits and advantages of using the Flat Cube – and in consequence engage customers to apply it. The Flat Cube has many benefits, for example, improved BW query performance and faster Data Transfer Processes… Read more

Customer Experience with Columnstore on ERP

SAP released the report MSS_CS_CREATE a few months ago. Using this report, customers can create an additional Nonclustered Columnstore Index (NCCI) on any SAP ERP table. This has already been described here: https://blogs.msdn.microsoft.com/saponsqlserver/2017/04/13/using-columnstore-on-erp-tables. In the meanwhile, several customers tested this feature. They reported performance improvements for reporting scenarios using huge aggregations (see below). Other customers… Read more

Customer experience with SAP BW FEMS-Pushdown

A few months ago we released a new SAP BW statement generator, which increases BW query performance for complex queries containing FEMS filters, see https://blogs.msdn.microsoft.com/saponsqlserver/2017/03/06/bw-queries-by-factors-faster-using-fems-pushdown. In the meanwhile, a few customers who tested the new feature, provided feedback to the “SAP on SQL Server development”. Based on this feedback, we further improved the performance of… Read more

Parallel Processing in SAP

New generations of CPUs do not provide any significant single-thread performance improvements. Instead, the number of logical CPU cores is increasing with each new CPU generation. You can significantly reduce the runtime of a task by running sub-tasks in parallel on many CPU cores. However, splitting a task into sub-tasks consumes additional resources (CPU and… Read more

Performance evolution of SAP BW on SQL Server

In SAP customer support, we still see several customers running old SAP BW code that cannot leverage the improvements we delivered within the last years. In this blog, we want to demonstrate the huge performance improvements which can be achieved even without hardware replacements. Until 2011, the standard configuration of BW queries on SQL Server… Read more

BW Queries by factors faster using FEMS-pushdown

Complex SAP BW queries often contain FEMS-filters. These filters used to be applied on the SAP application server, which was not very efficient. A new SQL statement generator in SAP BW implements an optimized algorithm for FEMS processing. We have seen performance improvements up-to factor 100. The actual performance improvement varies heavily for different BW… Read more

Recent SAP BW improvements for SQL Server

Over the course of the last few months we implemented several improvements in SAP BW. We already blogged about two improvements separately: https://blogs.msdn.microsoft.com/saponsqlserver/2016/11/14/simplified-and-faster-sap-bw-process-chains https://blogs.msdn.microsoft.com/saponsqlserver/2016/11/25/improved-sap-compression-tool-msscompress In this blog we want to describe a few, additional improvements BW query performance of F4-Help Some BW queries were not using intra-query parallelism, because the BW statement generator did not… Read more
