  Key Concepts: 
  Pre-filter is a feature of SAP BusinessObjects Data Federator (EIM-DI-DF) that allows users to filter data before it is retrieved from the source. This helps reduce the amount of data that needs to be processed, resulting in faster query execution times. Pre-filtering also helps improve the accuracy of query results by ensuring that only relevant data is retrieved. 
  
  How to use it: 
  To use pre-filtering, users must first define the criteria for the filter. This can be done by selecting the desired columns and setting the appropriate conditions. Once the criteria have been set, users can then execute the query and only the data that meets the criteria will be retrieved. 
  
  Tips & Tricks: 
  When using pre-filtering, it is important to ensure that the criteria are set correctly. If too many conditions are set, it can result in an overly restrictive filter and not enough data being retrieved. It is also important to consider how the filter will affect query performance, as too many conditions can slow down query execution times.
