Hi, All, 

I am trying to calculate a variance between 2 fields. I have the following in my formula, but is picking up on Opportunity name only, we would like to see it by each quote line, and I was wondering if anyone can point out what I may be doing wrong? Thanks! 

OpportunityLineItem.SBQQ__QuoteLine__c.Displayed_Net_Total__c:SUM - PREVGROUPVAL(OpportunityLineItem.SBQQ__QuoteLine__c.Displayed_Net_Total__c:SUM, Opportunity.Name)

I am trying to create a validation rule on Price Books, Products, and Price Book Entries. 

(($User.Epicor_business_unit_code__c
 = 'CADMM' && Contains(TEXT( Default_Product_Line__c ),"Materials & Minerals")))

||

(($User.Epicor_business_unit_code__c
 = 'EPDRMSI' && Contains(TEXT( Default_Product_Line__c ),"Radiation Measurement and Security Instruments")))

However, when I use this condition without a IF, it does not work. When using IF, it works, but I am having issues locating a field to pick our picklist for Product Family on Price Book Entries. I am getting a lookup to Product Field (Product2.Family). Can anyone shed some light on this, please? Thanks in advance!
