A batch in Access Charity CRM will naturally filter out two kinds of payments: soft and header payments.
Soft payments
Soft payments are carbon copies of the original payment, linked to another contact.
Header payments
Header payments are used if the payments are split between two different areas. If a payment is split in two, there's 3 payments in total. The two splits, and a header for the total value.
Stop soft and header payments from appearing in a report
To stop both of these appearing in a report, add a filter to the Payment Type field.
The filter should be: Does not contain Soft, Header.
