Adding a Table field through X++ code in Dynamics Ax

   Sometime back there was a query in one of the discussion forum about inserting a table field through code. I did a small job to demonstrate that, just  thought would write that down in my blog too…… and here it is.
I have added sufficient comments to make it explanatory.   
 static void JobCreateTableFields(Args _args)
    //find the Table
TreeNode                   tablenode = TreeNode::findNode(#TablesPath).AOTfindChild(‘LedgerTable’);
    TreeNode                   fieldNode, tn;
    Struct                         properties;
    Struct                         propertyInfo;
    Array                          propertyArray;
    str                               propertyValue;
AOTTableFieldList    lst;
    str                               name;
    Counter                     propertyCount;
    int                               i;
    Map                            map = new Map(Types::String, Types::String);
    //Find the tables field node
lst = tablenode.AOTfindChild(‘fields’);
    //add the field
    //now find the node in the tree
    fieldNode  =  lst.AOTfindChild(‘Test’);
    //get the properties structure
    properties = fieldNode.AOTgetPropertiesExt();
    //Update the properties map with the required properties
    map.insert(‘ExtendedDataType’, ‘LedgerAccount’);
    // get the number of properties
    // and the array containing the properties structure
    propertyCount = properties.value(‘Entries’);
    propertyArray = properties.value(‘PropertyInfo’);
    for (i = 1; i < propertyCount; i ++)
        propertyInfo  = propertyArray.value(i);
        name = propertyInfo.value(‘Name’);
//see if we have inserted the property name in to the map
if (map.exists(name))
//set the property
  propertyInfo.value(‘Value’, map.lookup(name));
    //set the properties structure
    //save the treenode
//Let us open the table
    //and see if the code works 🙂

    Hi Kamal,

    Nice blog. It helps me to figure this out. But I still had some issues to get this to work.
    There is an easier way which is used more times in Ax to set the values of a field. The properties method can be used to sort this out. This one is using the array settings already.

    The properties macro contains all the names of the properties.

    str properties;
    if (fields.AxExtendedDataType)
    properties = FieldTreeNode.AOTgetProperties();
    properties = setProperty(properties,#PropertyExtendeddatatype, fields.AxExtendedDataType);

    kind regards,

    Hello Kamal!
    Nice blog entry…!
    One question, have you tried to add a field to the AOT without assigning an Extended Data Type?
    In my example AX throws an Exception if the Extended Data Type property is not filled.
    But for for (some) enums (e.g. ItemType) there is no Extended Data Type 😉
