How to add $ sign in JDE Report

We need to add $ sign to the first row and the last row of the report. But when working on the report from OMW, there is no $ format available for us to choose.

We tried to add a constant within RDA to display a $ on the proper lines of the report. The problem is if the number gets too big or too small the $ stays in its fixed position so there can either be too much space between the $ and number or the number can overlay on top of the $.

can you let us know how we can add the $ sign in front the number and the numbers are still right justified?
