All across Salesforce, there are lots of standard Quantity fields on standard objects, such as
- OpportunityLineItem.Quantity | Number(10,2)
- QuoteLineItem.Quantity | Number(10,2)
- OrderItem.Quantity | Number(16,2)
Now all these fields are defined as Number(16,2) or Number(10,2). What if we need more decimal places like Decimal(10,6)? Is this possible, or do we need to switch to a custom field - and as domino-consequence, do we need to swithc the entire mechanisms of TotalPrice-calculation on custom fields plus calculation-logic, too?
