Query Definitions 
The Query component of SAP Sourcing provides customizable access to data. In particular, queries drive the following:
Lists, such as My RFPs
Object pickers, such as Search Contents by Supplier
Channels, such as the To Do List channel
The selection of objects to be exported
You use the Query component to customize and extend these areas of the application. Working with queries requires knowledge of SQL and a basic understanding of the SAP Sourcing data model. The data model reference is available in a separate document through the SAP Professional Services organization.
SAP Sourcing provides an extensive set of queries by default. You cannot edit these queries, but you can duplicate a query to use it as a model for a custom query. You can edit custom queries as needed.
This section describes how to create and edit a query definition.
