Exist the price levels in Sage 50 CA?

I'm working on the integration of Sage 50 CA with a third party application with .NET. And price levels are within the required information extracted from the database Sage 50 CA, but so far I have not found any information to verify the existence of price levels in SAGE 50.

When I talk about price levels, I mean distitos prices that apply to a product, depending on the quantities sold. For example: 

Sales  for product No. 1 :

Quantity: 1 - 25 => Unit Price: $85.00

Quantity: 26 - 55 => Unit Price: $45.00

Quantity: 56 - 100 => Unit Price: $25.00

Quantity: 100 - + => Unit Price: $15.00

I need to know if price levels for customer exist in SAGE 50 CA 2016? And in what table of database could find this information?
