I have a custom salesforce object that I am trying to insert data into via the salesforce data loader tool. I can only see the object when I click export and click on "show all salesforce objects". When I do the same thing when I click on insert the object does not show up. Any ideas why I can't see this?
You should give the custom object edit/modify all permission under object settings in profile of the user which is logged in the data loader. I made the following changes to a profile for a test object and gave it just read permission, I was able to view the object while exporting but not during insert or update operation.
