The possibility to specify a role for running import jobs, which is required for environments where running in elevated administrator mode is not allowed, is available from Axiell Designer version 7.7.4.2134 and import.exe version 7.6.21161.1.

With the new fixed field mapping you can now steer what role is used for running the import job. When you add the following in the field mapping list you can set the role:
 
Source field                 |           Destination field
MY_PARTICULAR_ROLE               <ROLE>
 
So, the Source field column must contain a role known in the application (so instead of MY_PARTICULAR_ROLE, use an actual useful role name), under which the import must and can run, and the Destination column holds the reserved mapping id <ROLE>. This is a fixed string so enter the text <ROLE> literally. The runner will pick this up when run from Axiell Designer or using the command line import tool (import.exe).
