Create a new Boolean Formula Field - eg Is Active (Is_Active__c) ISPICKVAL(Status__c,"Active")
OR use an Extension to show different Icons based on different Picklist Values - eg Green for Active, Red for Inactive.
Create a new Text field that returns a 3 character (max) value based on Picklist values eg CASE(TEXT(Status__c),"Oh Hold","HLD","Waiting","WT!","Cancelled","X","ACT")
OR use an Extension for each Picklist value with a three character Static Text.
Create a Formula for Is High Value Donor (Is_High_Value_Donor__c) and use $$$ as the text or the green money bag icon. npo02__TotalOppAmount__c > $CustomMetadata.ReportingSettings__mdt.HighValueDonor.Amount__c
OR use an Extension to add value ranges for different levels of Donors (it will depend on if you want to store the values in Indicators CMDT or your own CMDTs).
You can traverse to parent field relationships by entering for example Account.IsActive__c in the Advanced Field field on an Indicator Icon for a Contact. Don’t enter anything in the Field field.
