This would be better handled by out-of-the-box functionality with the
flip sign box rather than using the complex expression. The admin could
put this into an excel or TRX file and upload it rather than building it
directly in the transformation rule...
It really depends on the client requirements and how the cube is set up.
Some want to see it only on the parent, others don't care and are fine
with reporting it on the entity. Some want it broken out by
eliminations, others want it on a separate UD.
