A roll-up summary field is a field that calculates values from related records. A roll-up summary field can be used to display the number of opportunities that are closed won with a close date within the last year on the account detail page by using a filter criteria on the field.

Putting the SC in the role hierarchy above the technicians whose work orders they review will provide the required access, given a private data model.

Users at any given role level can view, edit, and report on all data owned by or shared with users below them in the role hierarchy.

A summary report on the opportunity object should be created to add to the account page layout. A summary report groups rows of data by common values and allows users to create charts based on aggregate values.

The two reasons that could be preventing this relationship conversion are that there are already two master-detail relationships on the Invoice Line Item and that Invoice Line Item records exist without having the Invoice lookup field populated. A custom object can have up to two master-detail relationships, so adding another one would exceed the limit. Also, a master-detail relationship requires that the detail records have a value in the master lookup field, so any records with a blank Invoice lookup field would prevent the conversion.

The two reasons to create an unmanaged package are to distribute open-source projects on the AppExchange and to deploy from a Developer Edition environment. An unmanaged package is a collection of components that can be installed in any Salesforce org but cannot be upgraded or controlled by the developer.
