To ensure that the membership rollups in NPSP work properly, the following settings need to be configured:

Check that the Membership Record Type is Selected for Membership Rollups:

Go to NPSP Settings.

Navigate to "Settings" -> "Donations" -> "Customizable Rollups".

Ensure that the membership record type is selected and configured to be included in the rollups. This allows NPSP to aggregate membership data correctly.

Ensure there is an Opportunity Record Type Set Up for Memberships:

Navigate to Setup -> Object Manager -> Opportunity.

Ensure there is a specific record type for memberships (e.g., "Membership Opportunity").

Configure this record type with the necessary fields and settings specific to membership tracking.

By ensuring these configurations are in place, NPSP can properly roll up membership data and provide accurate metrics for the organization.
