Hello,If the missing feilds were fillable then there is nothing to take
with binding.Binding is associated with data file/connection that get
merged with XDP.So if the data is missing from fillable feild, that can
be recovered from the PDF that user has filled and save the PDF.If you
have all the PDFs from all user, use can assemble those using assembler
service and then extract the data from assembled PDF.Hope this helps.
