Accessing Lipper (Eikon) data through Datafeed Matlab 2015b

Hi,

I am trying to use the datafeed toolbox to download historical data on mutual funds. While toolbox examples work for me, I cannot get the functions to work with any fields relevant to mutual funds.

E.g.

s = 'AAPL.O';
fields = {'DATE','OPEN','HIGH','LOW','CLOSE'};
startdate = floor(now)-150;
enddate = floor(now);
period = 'M';
d = history(c,s,fields,startdate,enddate,period)

works, while if we change to

s = 'LP60075464';
fields = {'DATE','TR.FundNAV'};

we get " Error using treikon/history (line 99) #N/A *The record could not be found".

I have tried numerous RICs and fields with the same error.

Any help is greatly appreciated.

Also, if someone has a working example of accessing Eikon APIs from Matlab (not through datafeed) I would be ever so grateful too.
