List views were introduced in the PRPC 5 series (which is why they are sometimes referred to as V5 reports). They are significantly deprecated in Pega 7. If you are developing in Pega 7, you should avoid using them.
I believe you could achieve almost everything in Report Definition + Repeat grid configuration, which list view used to achieve. You would be wondering about the getContent activity customization with Report Definition, which list view used to support. There is a way to achieve this as well, You can achieve this using Data Page + Report Definition + Your activity combination. Get the results from Report Definition, configure this RD in the Data Page, configure your activity in the Post Processing Activity of data page (Use this activity to customize your results, which we usually do to customize the List View results ). Later you can configure Data Page + Repeat grid in the UI to represent your results.
Moreover RD does the job of both summary view + list view.
Please let us know if you find anything which you cannot achieve using RD.
