How to create EDT from code

It is impossible to create EDT from X++ using standard AOTAdd. AOTCompile causes Axapta crash and than unstable work. AOTSave method virtually doesn’t save anything.
Solution: Use export/import methods.
Steps:

1. Find any EDT node using AOT methods.
2. Use SysTreeNode::CopyNode() to copy node to the new EDT node.
3. Change properties according to the needs for the new node.
4. Export new node EDT to temporary folder.
5. Parse exported file and set USERTYPE property the same as NAME property.
6. Import changed xpo file.

How to access field in a table using this field id

To do this you could use next construction:
myTable.( filednum( myTable, myField ) ) = “XXX”;
This is the same as
myTable.myField = “XXX”;
Example:
Field AccountNum from CustTable have id 1. Then statement CustTable.(1) = “4000” – will initialize field AccountNum with value “4000”.
You could also use this feature while working with record of type Common.
Example:

    Common      common;
    CustTable    custTable;
    ;
    select custTable where custTable.AccountNum == "4000";
    common = custTable;
    info( common.( fieldnum( custTable, Name ) ) );

The output of running this code will be the info log with a message “Light and Design”, Where “Light and Design” – name of the customer with id “4000″.
