In Claim header table, i was able to copy the Primary column "Pre approval Refrence"  to the Cliam header table, but status column is not copied.

want to know, how to copy status column too, below is the code i used to copy Primary column " Pre approval refrence"

function enableclaimcreate(SelectedControl)
{
var returnflag = true;
return returnflag;
}

function onclickinitiateClaim(SelectedControl)
{
var selectedRow = SelectedControl.getGrid().getSelectedRows().get(0).getData().getEntity();
selectedRow._attributes._collection.cs_claimcreationinitiate.setValue(true);
var entityFormOptions = {};
entityFormOptions["formId"] = "1533E4B3-5087-ED11-81AD";
entityFormOptions["entityName"] = "cs_claimrecordheader";

entityFormOptions["windowPosition"] = 1;
entityFormOptions["navbar"] = "entity";

// Set default values
var formParameters = {};
formParameters["cs_preapprovalreference"]=selectedRow.getEntityReference();       //cs_preapprovalreference is Pre approval refrence column in Claim header table  
Xrm.Navigation.openForm(entityFormOptions, formParameters).then(
function (success) {
console.log(success);
},
function (error) {
console.log(error);
});
}

Tried adding below code to above to update status but it didnt work:

var formContext = executionContext.getFormContext(); 
var ApprovalStaus = formContext.getAttribute("statuscode").getValue(); //statuscode is column name of Pre Approval Header table

formContext.getAttribute("cs_claimstatus").setValue(ApprovalStaus); // cs_claimstatus is column name of claim Header table.
