• Key Concepts: 
  A case statement is a type of query used in SAP BusinessObjects Data Federator (EIM-DI-DF) to retrieve data from multiple sources. It is similar to an IF-THEN-ELSE statement, but it allows for more complex logic and multiple conditions. The case statement is used to evaluate a set of conditions and return a value based on the result. 
  
  How to use it: 
  The case statement is used in the SELECT clause of a query. It evaluates a set of conditions and returns a value based on the result. The syntax for the case statement is as follows: 
  CASE WHEN condition1 THEN value1 WHEN condition2 THEN value2 ELSE value3 END 
  The conditions can be any valid expression, such as a comparison operator or a function. The values can be any valid data type, such as strings, numbers, or dates. 
  
  Tips & Tricks: 
  When using the case statement, it is important to remember that the order of the conditions matters. The first condition that evaluates to true will be returned, so make sure that the most specific conditions are listed first. Also, make sure that all possible conditions are accounted for; if none of the conditions are true, then the ELSE value will be returned.
