    Why Doesn't the

    Composite Provider Show Any Results?

    Applies to

    SAP NetWeaver Business Warehouse 7.30 (BW7.30) SP05 with SAP NetWeaver Business Warehouse Accelerator 7.20 (BWA7.20) or HANA 1.0 running as a database for SAP NetWeaver BW 7.3 SP05

    Summary

    This article describes how the Join Analysis Methods of the BW Workspace Designer can help the Business Analyst to find out why the newly created data model does not return any values. As a prerequisite we recommend reading the article ‘What is a BW Workspace?’ and ‘How can Central and Local Provider easily be combined?’ from this article series.

    1. Introduction

    A BW Workspace is a kind of ‘small sandbox’ which IT defines. IT sets the boundaries, IT sets the amount of resources that a BW Workspace can consume and exposes some of the central data models to the BW Workspace (data of the models and their related semantics). The BW Workspace exposes the central data in a logical fashion only. The data is not copied over into the BW Workspace, which means that no data replication is needed. The goal is to enable the Key Business Users to use this functionality in a dedicated and separated environment, which is deeply embedded and integrated in the existing BW landscape. The BW Workspaces bridge the gap between the architected and the departmental data marts. Therefore, Workspaces are integrated, independent and, as the usage of the SAP Business Warehouse Accelerator is mandatory, they are completely in-memory.

    2. Check Types and Location

    There are different types of checks which can be used in order to find out why a CompositeProvider does not show any values or not the expected ones. There are checks which can be executed per join field or per combination of fields as well as you can execute checks for a single Provider or for all Providers. Finally there is a method which checks the Providers step-wise.

    2.1. Join Fields Analysis (Single Field Link)

    An analysis can be executed for a single field link. This type of analysis is possible in the mapping step where you link fields, as well as in the graphical and table view on step 2 (Model CompositeProvider). It is the same check as the Join Fields Analysis for a selected or all Providers but executed on basis of the selected field only.
