Fiori Track Sales Order, no Customers?

Hi everyone,

I am working a couple of weeks on configuring Fiori, i managed to get the Track Purchase Order app working properly.

Unfortunaly the app Track Sales does not work, i cannot find any Customers, but i am a Sales Representative and Sales Employee of some customers. Also, in SAP itself, i can create a Sales Order but i cannot get it in this app.

Here is the screenshot, whatever i search for (name, *, customerid) i don't get any results.

With Chrome i inspected the element and got this result:

In the gateway client i get the following error message:

I hope that you can help me figure this out.

Regards,

Bas
