I am using fold multiple columns in my prepare recipe, the output in not preserving empty values. Is there any way to ensure that the empty values are preserved.
The DSS documentation says the empty values will be preserved but I am not seeing that in the result
Indeed, I've been trying to reproduce and it seems empty values are not taken into account.
A possible workaround is to:
a) Fill empty values in multiple columns (with 'N/A') for instance
b) Fold multiple
c) Find and replace 'N/A' with empty values
Hope this helps
