Explanation
To ensure that only invoices with status paid are included in the rebate calculation, the admin should validate the invoice status in the ERP system before bringing the data into Salesforce. This way, the admin can avoid importing unnecessary or inaccurate data that might affect the rebate performance and payout. The other options are not feasible or efficient because:
Option B is incorrect because transactions with any status are included in the journal by default. The admin needs to set up eligibility conditions in the rebate types to filter out transactions based on status or other criteria1.
Option C is incorrect because creating a custom field in the transaction journal and copying the invoice status data into it is redundant and time-consuming. The invoice status is already available as a standard field in the transaction journal object2.
Option D is incorrect because updating the data processing engine job to filter out transactions based on invoice status is not possible. The data processing engine job is used to process the data from the transaction journal into the rebate journal, and it does not have any filtering options3.
