I have questions regarding custom objects in Salesforce that might have been answered in discussions. BTW, I'm using developer version of Salesforce currently.
1. Is it not possible to have two master details data type in one object? How do you get around it?
2. Can a custom report use data from three different objects, not just two?
I have created a field external_opp_id in my opportunity and marked is as an external ID field. When it comes to task, the data loader GUI, it doesn't give me an option to select External ID field. It assumes SF field to be there. It works when I put SF Id for opportunity. but I really need to do it through external ID, as the numbers of both tasks and opportunity are huge. Quick help is appreciated.
