I've had a bash at the #Advanced Mapping​ Recurring Donations Recipe. This brings in the Recurring Donations and the first Opportunity is created by the NPSP Data Import.

Recurring Donations Recipe

Attach a Recurring Donation to Contact1

To link a Recurring Donation to Contact1, follow the steps below.

1. Prepare Salesforce for the Recurring Donations Object Group, and create these fields on the NPSP Data Import object:

• Recurring Donations Imported (lookup)
  • Recurring Donations Import Status (text)

1. Add at all the fields to map on the NPSP Data Import object. Make sure the field type matches the type on the Recurring Donations Object, such as:

• Recurring Donations Type  (Text)

1. In NPSP Settings, create a new Object Group for Recurring Donations 1 with the following information:

• Group Name: Recurring Donations
  • Object Name: Recurring Donations
  • Is Child/Parent: Child
  • Of This Mapping Group: Contact 1
  • Through This Field: Contact
  • Link to Field: Recurring Donations Imported
  • Import Status: Recurring Donations Import Status

1. Add Field Mappings for the Recurring Donations  Object Group:

• Select Recurring Donations Type (Recurring_Donations_Type__c), and map it to Recurring Donations Type (npsp__Recurring_Donations_Type__c)
  • Repeat for all fields to be mapped.

Notes:

• You will need to create another Object Group and mapping if you wish to import to Account1.
• I would recommend setting a value and mapping for Recurring Donation Name field else it will default to the Recurring Donation ID.

I also have screenshots if they would be helpful.
