Junction objects are used to create many to many relationships between objects. If you take the Recruiting application example, you can see that a Position can be linked to many Candidates, and a Candidate can apply for different Positions. To create this data model you need a third object "Job Application" that links the 2.

So you'd create a lookup field for both Position and Candidate object on the "Job Application" object. This will establish many to many relationship between Position and Candidate via the "Job Application" object known as the junction object.

The property of split() is such that the list you get back always has at least one element. You are splitting the empty string, and so you're getting back a list of size 1, where the element in the list is the empty string.

Yes Brian you are right that opportunity line item is not available in custom report type but if you want to create report of Products filter by opportunity line item fields then you can follow theses steps-

* Select report type "Opportunity with Products" and Create.
* Select "Summary format" and create grouping with Product and then Opportuniy Product so this will show
products with related Opportunity products.
* Add normal filter then in the picklist you can find opportunity product fields also.

Note- But we can not apply filter on "Number of records" of OpportunityProducts related with Product.
