• Key Concepts: 
  A constraint is a rule that is applied to a data set in SAP BusinessObjects Data Federator (EIM-DI-DF). It is used to limit the amount of data that is returned from a query. Constraints can be used to filter out unwanted data, or to ensure that only certain types of data are returned. 
  
  How to use it: 
  Constraints can be applied to a query in SAP BusinessObjects Data Federator by using the “Constraint” tab in the Query Builder. Here, users can specify the type of constraint they want to apply, such as a range, list, or comparison. They can also specify the values that should be included or excluded from the query results. 
  
  Tips & Tricks: 
  When creating constraints, it is important to consider how they will affect the query results. For example, if a range constraint is applied, it may be necessary to adjust the range values in order to get the desired results. Additionally, it is important to consider how multiple constraints will interact with each other when creating a query.
