Some users may find that when they use Summary Information as part of their Criteria and it contains the filter of 'Campaign ID does not equal [X] or Campaign ID not one of [X}' they may get incorrect results from split gifts. This can also occur for Fund ID or Appeal ID as well, and also for Fund, Campaign, or Appeal Attributes.
We are currently evaluating this issue and will update this article when we have more information.
When using the Summary Information field in the criteria, Instead of using the filter 'Campaign ID does not equal [x]', use the filter 'Campaign ID one of' and bring over all the campaigns except the campaign that is not desired.
Steps to Duplicate
Using example of donor from Sample Data:
Go into Robert Hernandez and go to the gift tab > new gift
Make it a Cash gift
Gift date today's date
Gift amount $100
Go to the Split gift tab
Split between Campaign Y and Campaign Z equally (use any two campaigns)
Add any two Funds
Save and Close
Go to Query > New Query > Constituent / Dynamic
In Criteria: Summary Information > Summary for Gift > Total Amount of gifts greater than or equal to $1.00 and on the filter tab > go to Gift date equals today AND Campaign ID does not equal X (any of the campaigns you did NOT select for the gift)
On the output tab, include Query Fields > Total Amount of Gifts_1
Results show $200
It should only show $100 since the gift you just added was only $100 and it fits the criteria.
This will occur if you do the same thing with Fund ID and Appeal ID (or Description for any of them). It will also occur for the "Not one of operator" as well.
