I've never run into this problem before, but I have a site where there are multiple sellers (anyone can become a seller) and I can't figure out what permission is required to allow a user to set product weight and dimensions. I've been checking and unchecking but still can't figure out what's needed.
Probably "edit own products" under uc_product module. You could also do "edit products", but that means anybody could edit any product node.
Now, this also means that they can change a lot more than just the weight and dimensions, but if you're letting people create their own products, that probably isn't a problem.
A year later, I have the same problem.
Does anyone know the answer to this?
I tried giving a role access to all permissions. They were still unable to set product dimensions, weight, or how many were available in stock.
I'm very confused.
I have discovered the problem through a passing comment someone made about "weight" in the 10th comment of this thread http://drupal.org/node/591474
Apparently, there is a checkbox titled "hide extra fields" in home>>administer>>store administration>>configuration
This needs to be OFF for your sellers to have full access. This being on by default seems extremely annoying to me, but maybe it is helpful for others.
