• Key Concepts: 
  Key date derivation type is a feature of BW-BEX Business Explorer that allows users to define the way in which key dates are derived from the data source. Key dates are used to determine the time period for which data is retrieved from the source. 
  
  How to use it: 
  To use key date derivation type, users must first define the key date field in the query. This field can be either a fixed value or a variable value. Once the key date field is defined, users can then select a derivation type from the available options. The available options are: Relative, Absolute, and Calendar Year. 
  
  Tips & Tricks: 
  When selecting a derivation type, it is important to consider how the data will be used. For example, if the data will be used for forecasting purposes, then it may be best to select a relative derivation type. On the other hand, if the data will be used for historical analysis, then an absolute or calendar year derivation type may be more appropriate.
