The combining process allows the user to integrate different dictionaries of a single question between multiple datasets. The process actually changes dictionaries and merges them, as opposed to the “mark as compatible”, which does not apply any changes to question dictionaries.
As it is for now, if the same question between different datasets has any differences in its dictionaries (e.g., different labels for the same value or any new response), alternative dictionaries are created (the question is marked as orange in Query)
To allow making a study structure clearer, you can combine these dictionaries and create a new, integrated one.
