I am using a roll up summary field to SUM the currency of a custom child object. The child object has up to 12 currency records that need to be calculated. I had an issue where I was dividing a price by 12 to get each of the amounts needed. I currently have them in a ROUND formula. Because of the rounding, the last currency field needed to be changed to make the total amount due add up correctly. I used a formula Current_Price__c -( ROUND(Current_Price__c / 12,2) * 11) to find what the last payment would be. This is working great, but is messing up the Roll up summary field. How to the get the Roll up field to only SUM the amount listed? All of the fields it is summing has a ROUND() factor in the field.
Sorry... the caveat is that I dont know enough about how the fields are driven to know if there will be a create or update action made on the records so that the WFRs trigger appropriately.
