Custom field is not present
What does this mean?:
When you are copying recipes built by another user, it is possible that they had custom objects or custom fields added to standard objects that your salesforce does not have.
You could fix this error in a few ways.
1. You could delete the mappings for fields that you don't have
2. You could add the objects or the fields to your salesforce objects
To refresh the schema you may have to do a small trick..
Let's say the account record you copied from was customized. Let's say step 1 was search for accounts and looked like this
Switch it to something else, like this
And then back to accounts, like in the original. This will fetch your schema for accounts.
You can use the same technique to expose custom fields you have that don't show up in the mapping.
