Subforms added after main records creation have "null" IDs.

Subforms added after main records creation have "null" IDs.

Hi Zoho Community,

I added a subform (pre-populated) to my main form. I want all existing records to have this pre-filled subform.
When I manually edit an existing record, I can see the subform and the pre-filled values. But it does not show in the report until I manually do this "Edit" -> "Update" manipulation. I tried multiple Deluge scripts/bulk edits but it's not working, as it looks like the freshly added subform has no ID until I do this manipulation (Edit-Update).
It therefore looks like I have to go through all existing records manually.

I also tried to update all records through zoho.creator.updateRecord but it still doesn't assign the ID to these subforms (which I think is the issue here).

Do you know how to do this edit-update in batch ?

Many thanks for your help.
Kind regards,

Guillaume
