To convert Open Numeric variables into Single choice during the import and using the metadata transformation, you should follow the following steps:
- At the import data page, tick the box ‘Code open ended variable to categorical’ and click the New Transformation.
- Inside the MDT (meta data transformation) page, change the question types to single choice.
- Save your mapping and proceed with the import process and you will have this new single choice variable imported to your project.
Note: Dapresy has a limit of coding 1000 answers within a question. It is the function "open ended to categorical" that has a limitation on 1000 answers. A "normal categorical" doesn't have this limitation.
