Sales Quotes Internal Pricing not working

Hello Everyone,

I'm configuring a new c4c system and my sales quotes don't have the Pricing tab and are not determining the price for products, any ideas on why this might be happening?

I want to use Internal pricing (not integrated and have checked the document at https://scn.sap.com/community/cloud-for-customer/blog/2015/10/07/how-pricing-works-in-sap-cloud-for-customer and at http://scn.sap.com/docs/DOC-68030 without any luck.
