To track nested campaigns effectively, Salesforce Campaign Hierarchies can be utilized. Here are the steps to set this up:
Create Parent Campaign:
Create the top-level parent Campaign called "Friends of the Organization".
Create Sub-Campaigns:
Create sub-campaigns under the parent campaign for each hierarchical level: FY19, Capital Campaign, Annual Fund, Digital Donations, and Mobile.
Link each sub-campaign to its parent campaign using the Parent Campaign lookup field.
Configure Campaign Hierarchy Settings:
Ensure the Campaign Hierarchy settings are configured to allow for the desired depth of nested campaigns.
Track Campaign Performance:
Use Campaign Hierarchy reports to track the performance of each campaign within the hierarchy.
Analyze metrics such as total donations, engagement, and conversion rates at each level.
By creating a structured Campaign Hierarchy, the nonprofit can effectively track and manage complex campaign structures, gaining insights into performance at each level of the hierarchy.

When troubleshooting the issue of Recurring Donation Opportunities having close dates at the end of the month instead of the 15th, the consultant should check if the "Always use last day of the month" field is selected. This field setting overrides other close date settings and defaults the close date to the last day of the month.
Log in to Salesforce: Access the Salesforce org where NPSP is installed.
Navigate to NPSP Settings: Go to the App Launcher, search for "NPSP Settings", and select it.
Find Recurring Donations Settings:
In NPSP Settings, expand the "Donations" section.
Click on "Recurring Donations".
Check the "Always use last day of the month" Field:
Locate the "Always use last day of the month" setting.
Verify whether this checkbox is selected.
If selected, uncheck this option if you want the close date to follow the Day of the Month picklist value.
Save the Settings: Save any changes made and verify that new Recurring Donations reflect the correct close date.
By ensuring this field is not selected, the system will correctly use the 15th of the month as specified in the Day of the Month picklist.
