That is true. However, the delivered Fiori application HCM_PEP_PROFILE uses this same gateway service. The delivered application queries the gateway service by PERNR as well and has a section for the qualification set.
In my application, on the left hand side, I see a number of employees and I select one, then I am also querying the same gateway service by pernr.
I was trying to review the delivered application to see how they do it. I'm having difficulty following it, but I noticed in the component-preload-dbg.js, their query path is essentially the same, they get the pernr then get the data. I don't know that I'm interpreting this delivered application correctly, but they seem to get back a list of the data then process it in this function:
sortedQualificationsList.forEach(function(result)
Do I need to implement something similar?
