Structure data object from MmsVariableSpecification is diffrent with value when received dataset from rcb

[Tivaty]

Problem:

Structure data object from MmsVariableSpecification is diffrent with value when received dataset from rcb

Code:

Debug.WriteLine("\t" + dataObj.name);
// when receiving data from rcb, we receive full dataset so we need index element to retrieve data correctly

List<string> daNames = con.GetDataDirectoryFC(ObjectReference.getElementName(dataObj.name));
for (int ii = 0; ii < daNames.Count; ii++)
{
    // only DA with same type FC is add to dataset tree
    if (ObjectReference.getFC(daNames[ii]) == ObjectReference.getFC(dataObj.name)) 
    {
        string daName = daNames[ii];
        string daRef = ObjectReference.getElementName(dataObj.name) + "." + ObjectReference.getElementName(daName);

        var daElements = new DataElement(daRef, rcbRef: dsNode.rcbRef, dsNode.rptId, new List<int>(doElement.ElementIndex));
        daElements.ElementIndex.Add(ii);

        MmsVariableSpecification specification = con.GetVariableSpecification(daRef, ObjectReference.getFC(daName));

        Debug.WriteLine("\t\t" + daName + " : " + specification.GetType() + "(" + specification.Size() + ")");
        doElement.AddChild(daElements);

        if (specification.GetType() == MmsType.MMS_STRUCTURE)
        {
            for (int iii = 0; iii < specification.Size(); iii++)
            {
                MmsVariableSpecification elementSpec = specification.GetElement(iii);

                string daSpecName = daRef + "." + elementSpec.GetName();
                var daSpecElement = new DataElement(daSpecName, dsNode.rcbRef, dsNode.rptId, new List<int>(daElements.ElementIndex));
                daSpecElement.ElementIndex.Add(iii);

                Debug.WriteLine("\t\t\t" + elementSpec.GetName() + " : " + elementSpec.GetType());
                daElements.AddChild(daSpecElement);

                if (elementSpec.GetType() == MmsType.MMS_STRUCTURE)
                {
                    for (int iiii = 0; iiii < elementSpec.Size(); iiii++)
                    {
                        MmsVariableSpecification elementSpecSpec = elementSpec.GetElement(iiii);
                        string daSpecSpecName = daSpecName + "." + elementSpecSpec.GetName();
                        var daSpecSpecElement = new DataElement(daSpecSpecName, dsNode.rcbRef, dsNode.rptId, new List<int>(daSpecElement.ElementIndex));
                        daSpecSpecElement.ElementIndex.Add(iiii);

                        Debug.WriteLine("\t\t\t\t" + elementSpecSpec.GetName() + " : " + elementSpecSpec.GetType());
                        daSpecElement.AddChild(daSpecSpecElement);
                    }
                }
            }
        }
    }
}

Result when read DataObject atrribute names:

Result when received a rcb:

The GetDataDirectoryFC function is based on the get-name-list-service. This service returns the result in alphabetic order and not the real order in the data model. Therefore this service is not suitable to determine the order of elements in data set entries.

==> Please tell me which service or method I can get the correct order of data set / data object entries

@mzillgith Please, Can you tell me how to get the correct order of Data Attribute name ? I can not parse data from Dataset - Report because I can not get to the correct order name
