Solve Data Drift Issues in a Rep's Statement with Historical Data
Data that changes over time causes data drift. For example, an opportunity that changed ownership as it moves through different stages can show up in a rep's data filter in Q1 but not in Q2. Salesforce Spiff administrators sometimes need to know the commission value from a previous period, such as how much a rep earned on new deals three months ago. Because of data drift, that value can be different now than it was when the commission statement was first calculated. To overcome this issue and look up past commission statement and payout rule values, use the amounts_from function.
