7.3 Expression Mapping

Expression mappings use formulas or expressions to transform source business terms into equivalent target business terms. There are 10 Expression Mappings.

Example:

• Source: Leg Type Code in PBSMCS
• Target: Leg Type Code (Expression) in DFCS
• Transformation logic (expression):

  CASE 
     WHEN [Leg Type] = 1 THEN 'PAY'  
     WHEN [Leg Type] = 2 THEN 'RCV'  
     ELSE 'NDER'  
  END
