Hi @venkat1 

Try like below

Create a variable "vTopInsurance" and assign the formula like below

=Concat(DISTINCT CAUSEDESCRIPTION, '|',-Aggr(Sum(CLAIMNO),CAUSEDESCRIPTION))

and use the below expression in textbox

TextBox1: =SubField(vTopInsurance,'|',1)

TextBox2:=SubField(vTopInsurance,'|',2)

TextBox3:=SubField(vTopInsurance,'|',3)
