IFCPROPERTYSINGLEVALUE Name & Nominal Value Updation based on GlobalId - Shared / Not Shared

Dear Experts,

I am a beginner and doubt on updating of Nominal Value with Name “SKIFCEPMSTATUS”

#187= IFCPROPERTYSINGLEVALUE(‘SKIFCEPMSTATUS’,$,IFCLABEL(‘erected’),$);

//create instance for new ifc file
IfcStore MyIFCData = IfcStore.Open(inputfile);

// get one single element by its unique identifier
IfcObject SingleIfcObject = MyIFCData.Instances.FirstOrDefault(d => d.GlobalId == MyIfcGloballyUniqueId);
if (SingleIfcObject != null)
{

//Get Property set of SingleIfcObject
List<IIfcPropertySingleValue> MyIfcPropertySet = SingleIfcObject.IsDefinedByProperties.Where(r => r.RelatingPropertyDefinition is IIfcPropertySet).SelectMany(r => ((IIfcPropertySet)r.RelatingPropertyDefinition).HasProperties).OfType<IIfcPropertySingleValue>().ToList();
if (MyIfcPropertySet != null)
{
    //Get the Name from the MyIfcPropertySet
    IIfcPropertySingleValue assemblyPosProperty = MyIfcPropertySet.FirstOrDefault(p => p.Name == ifcepmstatusfieldname);
    if (assemblyPosProperty != null)
    {

        //Check Nominal Value exists and not null
        if (assemblyPosProperty.NominalValue != null)
        {
            string existnomval = assemblyPosProperty.NominalValue.ToString();
            //Check whether nominal name is shared or not
            //if shared need to create new IFCPROPERTYSINGLEVALUE for ifcepmstatusfieldname with value EPMStatus
            //if not shared then need to update existing IFCPROPERTYSINGLEVALUE
            using (var txn = MyIFCData.BeginTransaction("Update NominalValues"))
            {
                assemblyPosProperty.NominalValue = new IfcLabel(EPMStatus);
                updct++;
                txn.Commit();
                flag = true;
                MyRow.Cells["ifcepmstatus"].Value = EPMStatus;
                rmk = "Status Updated";
            }
        }
    }
    else
    {
        errct++;
        rmk = ifcepmstatusfieldname + " not found";
    }
}
else
{
    errct++;
    rmk = "pSet not found";
}

}

else
{
errct++;
rmk = “ID not found in IFC”;
}

// Save the modified model
if (flag == true)
{
MyIFCData.SaveAs(outputFile, StorageType.Ifc);
Console.WriteLine(“IFC file saved successfully.”);
}
else
Console.WriteLine(“No Changes.”);

MyIFCData.Close();
MyRow.Cells[“ifcrmk”].Value = rmk;

I could not get whether shared or not and nominal values update other element also.
