Calling a Bound Function in CAP against SAP-Business-One-Servicelayer

[MatLakaemper]

Hello,

I have prepared a Function in SAP-Business-One in order to get a Joined Sql-Result.
This function is callable via the Servicelayer.

The Idea is, to call this function via CAP, but this doesnt work in the moment.

I would appreciate to get any help.
