When attempting to delete Constituent Information from the RELO plugin, you may encounter the following error:
One or more of the constituents selected were not rejected. The Constituent has pending gift information to transfer. You cannot reject a constituent with pending gift information.
This error appears because RELO requires that the constituent information be committed to RE when there are pending gifts.
If your goal is to remove the constituent and gift, you will first need to accept the contact in to RE before you can reject the gift. Once the contact has been created in RE, you can reject the gift and then remove the constituent from RE.
