To ensure that the status for a Campaign Member on a fundraising campaign is automatically updated when a donation is received from that Contact, the Automatic Campaign Member Management feature in NPSP can be used. Here's how to enable and configure it:

Navigate to NPSP Settings:

Go to Setup.

In the Quick Find box, type 'NPSP Settings' and select it.

Enable Automatic Campaign Member Management:

In the NPSP Settings, navigate to 'Donations'.

Find the 'Automatic Campaign Member Management' section.

Enable this feature by checking the corresponding box.

Configure the Settings:

Define the criteria for when and how Campaign Member statuses should be updated. For example, you can specify that the status should change to 'Responded' when a donation is received.

Save Settings:

Save the changes to activate the automatic updates.

This setup ensures that Campaign Member statuses are updated automatically based on the criteria defined, reducing manual effort and improving accuracy.
