Notes:
- If you have a lot of partner and employee records in your system you might want to consider creating partner and employee acquisition program so these records don't impact your attribution reports.
- It's best practice to block field updates for the acquisition field so you don't accidentally change the value. If you are intentionally changing the acquisition program for employees and partners it will not be possible to block field updates.
- See this article if you have records entering Marketo and acquisition program isn't being set.
