D365O - How to get current worker through X++

The current user or worker could be retrieved through following code since AX 2012

DirPersonUser::currentWorker()

However, In Dynamics 365 for operation this has refactored to;

HcmWorkerLookup::currentWorker()

AX 2012 : Remove an XML node through X++

Following code snippet may help you to remove an XML node from an XML message string.


private str removeXMLTag(str xml)
{
    XmlDocument         doc = new XmlDocument();
    XmlElement          nodeScript;
    XmlNode             parentNode, childNode;
    XmlNodeList         xmlScriptList,
                        parentNodeList,
                        childNodeList;

    int                 i,j;

    doc.loadXml(xml);

    // Get the root element and its child nodes
    nodeScript = doc.getNamedElement("SalesOrder");
    xmlScriptList = nodeScript.childNodes();

    for(i=0; i < xmlScriptList.length(); i++)
    {
        parentNode = xmlScriptList.item(i);
        childNodeList = parentNode.childNodes();

        for (j=0; j < childNodeList.length(); j++)
        {
            childNode = childNodeList.item(j);
            if (childNode.selectSingleNode("Notes"))
            {
                parentNode.removeChild(childNode);
            }
        }
    }

    return doc.outerXml();
}

This will remove DocuRef node along with its child nodes. 

Original XML message

<?xml version="1.0" encoding="utf-8"?>                            
<SalesOrder xmlns = "http://schemas.microsoft.com/dynamics/2008/01/documents/SalesOrder">                                        
<DocuRef class = "entity">
        <Notes>Business Name</Notes>
</DocuRef>

</SalesOrder>

XML message after node being removed

<?xml version="1.0" encoding="utf-8"?>                            
<SalesOrder xmlns = "http://schemas.microsoft.com/dynamics/2008/01/documents/SalesOrder">                                  
</SalesOrder>

AX 2012: Create sales order with delivery address from an XML file

Code snippet to create a sales order from an XML file.

private void createSOFromFile()
{
    AxdSalesOrder   salesOrder;
    AifEntityKey    key;
   
    Filename        fileName;
    RecId           salesTableRecId;
    SalesTable      salesTable;
   
    XmlDocument     xmlDoc;
   
    salesOrder  = new AxdSalesOrder();
    fileName    = @"C:\Temp\SalesOrder.XML";
   
    xmlDoc = XmlDocument::newFile(fileName);
   
    key = salesOrder.create(xmlDoc.xml(),  
              new AifEndPointActionPolicyInfo(), 
              new AifConstraintList());

    salesTableRecId = key.parmRecId();
   
    info(strFmt("Sales order created: %1", SalesTable::findRecId(salesTableRecId).SalesId));
}

Sample XML file
<?xml version="1.0" encoding="UTF-8"?>
<SalesOrder xmlns:n="http://schemas.microsoft.com/dynamics/2008/01/documents/SalesOrder">
   <SalesTable class="entity">
      <CustAccount>C000002</CustAccount>
      <InventLocationId>EMU</InventLocationId>
      <CustomerRef>Cash on Delivery (COD)</CustomerRef>
      <PurchOrderFormNum>4669286216,1021</PurchOrderFormNum>
      <ReceiptDateRequested>2011-11-11</ReceiptDateRequested>
      <DeliveryName>team03qa@gmail.com</DeliveryName>
      <TableDlvAddr class="entity">
         <City>southbank</City>
         <CountryRegionId>AUS</CountryRegionId>
         <LocationName>delivery address</LocationName>
         <State>VIC</State>
         <Street>13075 MANCHESTER RD STE</Street>
         <ZipCode>3006</ZipCode>
      </TableDlvAddr>
      <SalesLine class="entity">
         <ItemId>CANO</ItemId>
         <SalesQty>20</SalesQty>
         <SalesPrice>82.25</SalesPrice>
         <SalesUnit>ltr</SalesUnit>
         <LineAmount>1</LineAmount>
         <LineNum>8966003144</LineNum>
      </SalesLine>
      <SalesLine class="entity">
         <ItemId>CANO</ItemId>
         <SalesPrice>9.9</SalesPrice>
         <SalesQty>1</SalesQty>
         <SalesUnit>ltr</SalesUnit>
         <LineAmount>9.9</LineAmount>
         <LineNum>8966003208</LineNum>
      </SalesLine>
   </SalesTable>
</SalesOrder> 

How does it work

AxdSalesOrder class uses AifEntity classes to create sales order, these classes internally map the datasources of an AOT query AxdSalesOrder with the element tags in XML with attribute class = "entity". For example; for delivery address, the XML node name is TableDlvAddr which is the datasource name in AxdSalesOrder query.


Similarly, if you want to add notes or attach documents with sales order you can add DocuRefHeader node in XML file.

AX 2012: Reading XML Nodes under specific tag through X++

XML to read




















X++ Code 

For above XML structure, I will read all nodes exist within each InstructorAPIModel node. The getElementsByTagName() method of XmlDocument class can be used which returns XmlNodeList which can then be iterated to get node's values.

  XmlDocument doc = new XmlDocument();
XmlNodeList         apiModelList;
XmlNodeListIterator iterator;
XmlElement          apiModel;
XmlElement          firstName;
XmlElement          lastName;

doc.loadXml(_xmlMsg);

apiModelList = doc.getElementsByTagName('InstructorApiModel');
iterator= new XmlNodeListIterator(apiModelList);

while (iterator.moreValues())
{
    apiModel = iterator.value();
        
    firstName = apiModel.getNamedElement('FirstName');
    if (firstName)
    {
        info(strFmt("First Name: %1", firstName.text()));
    }
        
    lastName = apiModel.getNamedElement('LastName');
    if (lastName)
    {
        info(strFmt("Last Name: %1", lastName.text()));
    }

    iterator.nextValue();
}
