Answer 1

Try following solution based on Muenchian grouping. The TXLifeRequest are grouped by FundCode and AccountNumber.

It shout work even if there are more than two entries in the group. All Data for a group output (especial ReversalInd) is from the one with the highest TotalAmount. The value of TotalAmount is the difference of the first (highest) TotalAmount and the remaining ones.

It also considers the request: "And also if you observe the that is CR/DR should be identified based on highest TotalAmount value."

xsl:stylesheet version="1.0" 
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:ns="http://ACORD.org/Standards/Life/2">



    

    

        
            
        
    

    
        

            
                
                    
                    
                        
                        
                            
                            
                                
                            
                        
                    
                
            
        
    

Which will generate following output:

  
    LTRW00
    34142
    Cr
    1250
  
  
    LUL500
    34142
    Dr
    300
