SAP Lumira Designer getdata() with parameters

Posted on Oct 25, 2019 at 08:00 AM 588 Views

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,

dimitris

    Hello Dimitris,

    making "SalesAmount" and "memberKey" a variable is simple:

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

    However making "Dimension" variable is kind of tricky, as JSON always have constant keys.

    For this we added the function Convert.stringToDataSelection(). You can use it to create an empty selection that you extend 

    var sa = "SalesAmount";
var mk = "memberKey";
var dimKey = "Dimension";
var selection = Convert.stringToDataSelection();
selection[dimKey] = mk;
var cell = DS_1.getData(sa, selection);

    or you can "parse" a selection string:

    var sa = "SalesAmount";
var mk = "memberKey";
var dimKey = "Dimension";
var selectionString = '{"' + dimKey +'": "' + mk + ' "}'
var selection = Convert.stringToDataSelection(selectionString);
var cell = DS_1.getData(sa, selection);

    Some other example is here:

    Hi,

    Thank you for your answer.

    Measure works OK but I cannot make the dimension work.
