What im looking to do is the following:

Effect Target ability with a designated range (lets say 8 as a standard)

When you order the unit to use the ability, it launches a projectile (or does its thing, lets say a beam) in a straight line up to the maximum designated distance (range 8)

It should not matter where you click, it should always fire at the same distance.

How would you go about doing this? 

Would that be Location Offset - End Value?

Sorry tried this out without success. It's actually related to my other question with the issue order, which works now. Essentially I have a create persistent which creates a target unit at a location. I need it to always create the target unit at the maximum distance of the ability range regardless of where the player clicks. I did try source as you suggested but that doesn't seem to work.

EDIT

Okay I finally figured out what you are talking about. Do you have a link to a recommended tutorial for working with offsets? I have no idea how to set those offset values and Im highly interested in learning more as it could help me with a bunch of other issues.

THANK YOU!
