Referring the exported data with follow up survey on designer?

how we can use previously collected data for follow-up survey().the aim of this survey is to compare and contrast the exported data with newly collected data ,how do we can reference the exported data on designer?

Hi,
this is something you do not within the Survey Solutions Designer. Instead, you will include the previously collected data on the server of your survey during creation of ASSIGNMENTS through PRE-LOADING.

See below for a related discussion:

Relevant documentation by the Survey Solutions Team:

  1. Assignments
  2. Avdvanced preloading
  3. Protecting pre-loaded answers
  4. Numbering in subordinate rosters during preloading
  5. Errors in user-supplied files for preloading
  6. Design/Preload limitations by question type
