Hi there. sorry for my late reply.
I had a look inside the abap-code and i found the top-query part.
ls_paging-top = "io_tech_request_context->get_top( ).
i changed it to
ls_paging-top = 500. but i still getting only 50 entrys. maybe Im completely wrong.
if found that part inside the runtime artefact GET_ENTITYSET
any ideas? Thanks.
