In order to process transactions in the Blackbaud NetCommunity plugin, a user will need security rights to view, add, or edit the records within The Raiser's Edge.  If users do not have rights in The Raiser's Edge to the type of  transaction being processed, they will not see the transaction type within the Blackbaud NetCommunity plugin.  To resolve this, see How to set up security.

If you have Transaction Assignments enabled for this transaction type, you may also need to modify these to include this user or remove the assignment from options.  For more information, see Using transaction assignments to limit who can process certain transactions and the Transaction Assignment section of the NetCommunity and Raiser's Edge Integration guide.
