I have added custom fields to the Lead object on my development sandbox.
I want to deploy these custom fields to my qualification sandbox.
I use the welkin suite deployment tool which correctly detects differences on the Lead object and shows me the override option.
The problem is that my Lead object has managed package fields, and another developer working on the development sandbox has updated the managed package.
Managed package fields are different between the orgs so the deployment tool tries to apply these changes which result in error: "Cannot modify managed object".
For the moment I handle this problem using salesforce changeset to apply only selected fields changes.
Maybe a simple solution could be to skip managed package fields.
However it could be nice to choose which fields to deploy.
I hope my explanations are clear.
