I am trying to look at all tasks for a specific time frame, then create a note and set the LinkedEntityId to the whatid or whoid. This code creates the content note, 1 for each task. But then created a contentdocumentlink for each whatid or whoid for every note.
For instance, the query returns 8 tasks, 8 contentnotes are created and then each note is associated to each whatid(opps). So every opp has 8 notes. I have reworked this a million times and I am just not sure how to get it to know that I just want each contentnote associated to the task it "copied".
At this point I think I am over complicating it and the answer is so easy that I am not seeing it. How can I get this to create one note per task, and then associate it to the opp that the task is related? (whatid)
