Hello There,
You are not confused, whatever you guessing all are contributing to certain extent to get better paid in SAP.
All SAP Module consulants don't get paid same, more because of Demand and Supply not about how difficult or simple.
Shorter duration more bucks as you need to cover other aspects like more frequent travels, stays etc and all Idle time also taken to consideration between assignments.
If you are in Niche areas and Your client has bigger pockets then that is the best combination to demand more salary.
Projects of longer durations in the areas of BASIS, Portals are usually lesser billed because of the duration.
I have been closely working with Consulting industry for the past 16 years at various roles, have fair idea for sure.

Chakra Adari
