Field Mapping

For grid, multi grid, multi with capture order, numeric list, open text list, and ranking questions, which are all question types that can be seen as a collection of questions with one field for each item in the answer list, you can perform mapping at the field level as an alternative to question level mapping in a manually mapped combined survey. You can for example map an entire grid to another grid, or you can conduct field mapping to for example map fields from one grid to specific fields in another grid, map single questions to fields in a grid, or map fields in a grid to single questions (note that this last action is actually Question mapping, not Field mapping). Similarly, open text questions can be mapped to open text list and numeric questions to numeric list. Field mapping is necessarily a manual process; choosing which questions are to be mapped cannot be automated.

Here is an example where we have a grid question q2 in the combined survey, where the exact match isn’t found in the second survey.

To set up field mappings for a grid:

1. Open View/Edit Mapping for the combined survey and locate the grid question (here, q2).

   
   Figure 1 - The combined survey contains the grid but there is no match

2. Click Edit mapping.

3. Select Field Mapping for the question in the survey with “No match”

4. Pick the field you want to map and select Edit Mapping.

   Choose from the list of other grid fields and single questions that can be mapped. You can choose whether to show only fields and singles with matching scales (same number of answers and same codes) or not, and you can also switch between listing only unmapped fields or all fields.

5. Select the field you want to be mapped to the current grid field.

6. Click Insert.

   The field is mapped.

7. Repeat the procedure for all the fields you want to map.

8. On completion, click the X button in the upper-right corner of the overlay to return to the Edit mapping page.

To take away a mapping, click Field mapping and select Remove mapping on the field(s) you want to remove.
