I know that setting the _vLookupID /DFFSID is set by submitting a new item or editing and exiting item through a DFFS form.
I have a unique situation where my partners want to submit a large number of historical items via datasheet view in the parent list.
Rather than having to edit and save each item to create those IDs, is there a script that can be placed on the datasheet view page that will execute a DFFS function and create _vLookupID /DFFSID ?
