Hi,
I have a Database field in the Crystal report. It can be 16 to 20 characters length. I want to mask
all the characters with X except last four characters.

It can be ex:xxxxxxxxxxxx1234 or xxxxxxxxxxxxxxx3456

How to do this in Crystal 11.

Thanks

Use a formula field...

if length({table.field})=20 then
"xxxxxxxxxxxxxxxx" & right({table.field},4)
else
"xxxxxxxxxxxx" & right({table.field},4)

Since it can be 16 TO 20 in length try

Right("xxxxxxxxxxxxxxxx" & right({table.field},4),Length({table.field}))

Not sure what you mean by how.

The formula adds the 4 characters you want to a string of 16 x's producing a 20 character string with the left 16 masked as x
    xxxxxxxxxxxxxxxx1234
It then takes the right substring of the appropriate length for display.

Peter's formula will work, he limited it to 16 and 20 character lengths.
