• Key Concepts: 
  The query API is a component of the BW-BEX-UDI Universal Data Integration (UDI) module in SAP. It is a set of functions that allow users to access and manipulate data stored in the UDI database. The query API provides a way to retrieve, update, and delete data from the UDI database. It also allows users to create custom queries and reports.
  
  How to use it: 
  The query API can be used to access and manipulate data stored in the UDI database. To use the query API, users must first create a query object. This object contains information about the data that will be accessed and manipulated. Once the query object is created, users can then use the query API functions to retrieve, update, and delete data from the UDI database.
  
  Tips & Tricks: 
  When using the query API, it is important to ensure that all queries are properly formatted and that all parameters are correctly specified. Additionally, it is important to ensure that all queries are optimized for performance. This can be done by using indexes and other optimization techniques.
