Get date of fiscal year end using datatype code WC05350

Below are a few isins that return WC05350 as “NA”

• IE00BY7QL619

• US18482P1030

• US1251411013

• US0025353006

Here is the code snippet that I am using

publicstring GetData_SnapshotSingle()

{

var request = new DSDataRequest()

{

Instrument = new DSInstrument("IE00BY7QL619"),

DataTypes = new DSDataTypes("LOC", "EXNAME", "WC05350"),

Date = new
DSSnapshotDate(DSDateType.Relative(-30, DSDateFrequency.Daily)),

};

var response =
DSClient.DataService.GetData(request);

var respValue1 =
response["LOC"]["IE00BY7QL619"];

var respValue2 =
response["EXNAME"]["IE00BY7QL619"];

var respValue3 =
response["WC05350"]["IE00BY7QL619"];

returnstring.Format("{0}{1}, {2}{3}, {4}{5}",

"RIC
= ",
respValue1.Value,

"Exchange
= ",
respValue2.Value,

"Fisical
Year End = ", respValue3.Value);

}

Can you please advise how to get date of fiscal year end of above isins?
