Metadata and case data used by activities
With a couple of exceptions, all activities that run within UNICOM Intelligence Interviewer - Server Admin, including those installed as part of UNICOM Intelligence Interviewer - Server Admin, use the project's DataLocation property in DPM to find the questionnaire definition (.mdd) file and the case data for the project. If the .mdd file contains more than one version, all activities use the LATEST version. The exceptions are as follows:
The Status Reports activity uses the .mdd file in the Master project folder (FMRoot\Master\Projects\project_name), and reads the case data location from that file.
The Data Export activity and UNICOM Intelligence Reporter use a superversion of the data that includes all questions and other variables that are present in any version of the questionnaire.
