When uploading an spss file you'll see an option appearing to define the multiple choice question separator. Below you see the example:

An example of a multiple choice question is:

Which of the following did you purchase today:

  • Fast food
  • Beverages
  • Ice cream

This seems to be one question, but the answers are usually not stored in one column, but a column per answer, as below. 

During the import in Dapresy you can define if you would like these 3 variables to become 1. This is more efficient for reporting and will take less storage of data. The setting to define this is called the "Multi choice separator" which is in the example above an underscore. During the transformation, Dapresy will remove the postfix after the multiple choice separator and the postfix will become the answer id's. As an example, the multiple in the picture above will become Q3Mult with answers 1, 2 and 3.

Note: be careful in defining the multi choice separator. In case you have other variables which should not be a multiple but with this character, it will define these as a multiple too. 

Two other options belonging to the Multi choice separator, are "Compute an additional answer. This is used to correct the base size in case you have only missings for a respondent for all answers that belong to that multiple, but you would like to have this respondent counted in the base. In this case Dapresy can create an additional answer option which gets counted when a respondent didn't answer any.

Last but not least we can also group open numeric into a Multiple Choice Question.
