It is not possible to import objects to NAV 2013 R2 through the role tailored view, as such, it is necessary to open the Development version of R2 before uploading modifications to the system.
Open the development environment; click Tools > Object Designer. When open it will then be possible to import objects to R2.
Do this by selecting File > Import while the Object Designer is open.
Selecting Import will enable the appropriate objects.fob file to be imported into Navision. The user will be prompted to either Merge or Replace All new objects. With very few exceptions Replace All should be the option chosen as it will overwrite previous versions of the object and avoid conflict between the new and previous code.
After selecting all Replace All and OK the objects will be imported to Navision.
Compile The Objects
After importing the objects.fob to Navision, in the Object Designer select the button All on the left-hand side of the window. Then highlight all of the objects and press F11 to compile all of the objects.
