Hi Andrzej, We can customize/extend our Business Entity (Read() method) to support to support filtering, sorting and paging operations via JSON Filter Pattern. Following community post has some code samples pertain to JSON Filter Pattern community.progress.com/.../2279.business-entities-using-the-json-filter-pattern-code-samples Additional Details : We continue to use the same Read() operation (available in the Business Entity) which accepts filter string as the parameter. Only difference is that the client application sends an HTTP/S request to OpenEdge backend with an encoded JSON object having parameters for ablFilter, top, skip, etc. The OpenEdge backend then runs the Read() method in the Business Entity (ABL business logic with code to support the parsing of the JSON object in the filter parameter) and returns a temp-table or a DataSet with the results set that corresponds to specified parameters. Thanks and Regards, Anil Kumar.
