In order to view documents, the user must have access to Access Document Management (ADM), and have the relevant permission set in their accounts security profile.
In Access Evo, assign the user one of the Web access role types from the Members area:
An approver from Access Financials will have the permission set as default and so should now be able to view the documents in Approve.
An approver from Dimensions will need the **Documents** option enabled from within their security profile. This can be found under Invoice Register, Transactions.
