SAP Lumira Designer getdata() with parameters

Hi,

I have a function where I pass dimension and measure as strings.

I need to form a getdata() command like:

var datacell = DS_1.getData("SalesAmount", {"Dimension": memberKey});

but the "SalesAmount" and "Dimension" should be parameters.

I did a lot of examples but none worked for me.

Is there a way to make it work?

Regards,
