• Key Concepts: 
  Mapping rules are used in SAP BusinessObjects Data Federator (EIM-DI-DF) to define how data from different sources is combined and transformed. Mapping rules are used to define the relationships between the source and target data, as well as the transformations that should be applied to the data. 
  
  How to use it: 
  Mapping rules are created in the Data Federator Designer, which is a graphical user interface for creating and managing mapping rules. The Designer allows users to define the source and target data, as well as the transformations that should be applied to the data. Once the mapping rule is created, it can be deployed to a Data Federator server for execution. 
  
  Tips & Tricks: 
  When creating mapping rules, it is important to consider how the data will be used in order to ensure that the transformations are applied correctly. Additionally, it is important to test the mapping rule before deploying it to ensure that it produces the desired results.
