Description: This solution describes how to remove constituent attributes during an import
First you will have the attribute description you wish to remove in your data file. Map that attribute as you normally would if you were importing it.
You will also have a column in your data file with a value of Remove next to the attribute you wish to delete. This is mapped to Record Type = Constituent Attribute - Remove and Value Type = associate with the attribute you wish to remove. The value in your data file for the remove attribute column must be set to "Yes", "Y", or "1".
Note: Only constituent attributes can be deleted with IOM.
