In the Marketing and Communications area, you can create Export Definitions for the Marketing Efforts. Existing Export Definitions can also be edited to create a different result. When going to an existing editing an Export Definition this error is generated: “Object reference not set to an instance of an object.”
It is possible for this message to occur as a result of duplicate nodes within an export definition. For example, the following nodes may exist with their own fields:
Constituent Marketing Information 1 Constituent Marketing Information 2 Constituent Marketing Information 3 Constituent Marketing Information 4
In order to address this error, remove the duplicate nodes and add any fields applicable to Constituent marketing information under a single node.
