You have a deleted user in NetCommunity. You want to undelete them and generate a sign up request for the Raiser's Edge in order to link their NetCommunity record to their Raiser's Edge record. While reviewing their deleted record in NetCommunity, the link to undelete and generate sign up is missing.
Typically, this occurs if the user is also currently linked to The Education Edge.
To resolve, break the link to the Education Edge record. After it is broken, the link to undelete and generate the sign up request will be available.
