Create one formula for each field which will iterate through whole string and add one |(Pie) at the start and end of each character in string.
Example :
Local StringVar str := "";
Local NumberVar strLen := Length ({Customer.Customer Name});
NumberVar i;
For i := 1 To strLen Do
(
str := str +"|"+ {Customer.Customer Name}[i] +"|";
);
str
Hope this will help you..:)
