Hi - I am currently editing existing Sales Quote Forms on our C4C environment. I noticed that one of our forms has blank Data Connection whenever we edit this form, but for other forms it is existing.
Existing:

Non-Existing:

Question is, how can I add again the Data Connection for this impacted form so I can easily add our custom field in the Form I have created.
Thanks in advance for your responses!
Cheers,
Marc
