Building PAL Models using odata calls

Hi,

I have a procedure in HANA that builds a Decision Tree using PAL. I want to call the execution of this procedure using an ODATA call.

I am wondering if this is possible or must it be done in XSJS instead?

I know that read-only procedures can be called from Calculation scripts, which can easily be used by xsodata but my procedure is not read-only.

Thanks,

Colm
