Retrieve all data from a BO and display it in OWL

Hi Experts,

I am a beginner in the SAP ByD Development, and I have a requirement to display all customer ID and customer Names in OWL from the SAP ByD system.

the retrieve method needs at least one parameter and execute only a single retrieve of data, in my case I want to have a full list.

Any guidelines about how to retrieve all data from a BO and display it in OWL ?

Thanks.

Best regards.
