When we download the Interaction Details Report to generate internal reports, the interaction data that comes through is inconsistent. We have an example of a donor who showed up on a previous report but not the one we ran today. Why is this?
The Interaction DetailsReport returns no more than 30 days worth of data. It is very likely that your secondary report dropped off some of the interactions of a constituent that passed the 30-day threshold. For a more detailed listing of interactions, trying using the Query tool to query by Interaction Type.
