When SEPA & Classic fields are selected in Config > Business Rules, the options for Send Instruction and Type are disabled in the details section of a recurring gift or pledge when selecting direct debit as the Pay Method.
When you enable SEPA & Classic, you can still process BACS payments but you will not be able to use the Paperless Mandates option in Config -> General which controls the ability to send instructions.
1. Enable SEPA & classic fields in Config > Business Rules > SEPA 2. Open a constituent record then add a new Recurring Gift 3. Select Direct Debit as the pay method 4. Click on the Details button 5. Note the send instructions and type are disabled 6. Go to Config > General 7. Tick the option for 'Paperless Mandates Used' 8. Observe the error advising that you cannot use this when SEPA is enabled. This shouldn't be the case when using SEPA & Classic since we will be using the standard BACS processes at the same time as SEPA.
