If you have a client who has purchased a WIT Pack but can only access the Basic Data, the chances are that the client is running a BCI Survey alongside their Accreditation entry.
To grant your client access to all of their data in WIT, you just need to copy the assigned rights from the Accreditation survey to the BCI Survey.
In order to do this, you can go into Back Office | WIT | Rights Assignment, and choose the survey and the client that is not able to view all data. The page in front of you should look like the one pictured below (there may be a few rights already assigned in some cases, but in general the rights should be empty).
As you can see highlighted in the image, there is a check box at the top of the Survey Features section. All you need to do is put a tick in this check box, add a note and then click the 'Link' button (both at the bottom of the Survey Features section).
When the 'Link' button is clicked the page will reload and the newly assigned rights will be listed as check boxes in the top section of the page, titled with the clients name. At the bottom of the page a message will be displayed informing you that the rights have been copied over to the selected survey.
And that's it, your client should now be able to log into WIT and view all of their data!
