How to Define OData $top-Parameter for an aggregation binding

[nicolai_benz]

Setup: A UI5 Application using a OData Model

Target: Limit the data that is fetched for an aggregation binding by specifing the $top parameter

Why?: This solution works with any aggregation binding. Not only when using a control based on the sap.m.ListBase, which provides properties for specifing the number of records that should be returned.

Solution: In the definition of the aggregation binding specify the parameter "length":

Example:

In this example a list of the first three business partners should be rendered. Therefor only the first 3 need to be loaded.

This will then result in the following OData Request:

    ../BusinessPartnerSet?$skip=0&$top=3

I could not found this feature in the documentation so thats why I'm sharing this with you.
