Update the fields values from one field to another field while click the menu item button in form AX2012 :

2) Create menu item (Action) and add the created class for menu item.
3) Created menu item attached in form menu item button.

Ex Code:

Class:

class PMCopyEquipmenttoCLR
{

}

public void CopyEquipmenttoCLR(Args _args)
{
    PMSubJobLotLevelLines    pmSubJobLotLevelLines, pmSubJobLotLevelLinesloc;
    pmSubJobLotLevelLinesloc = _args.record();

    update_recordset pmSubJobLotLevelLines
              setting Additional4 = pmSubJobLotLevelLines.EquipmentNumber
                 where pmSubJobLotLevelLines.Selected == NoYes::Yes
                        && pmSubJobLotLevelLines.SubJobId == pmSubJobLotLevelLinesloc.SubJobId
                        && pmSubJobLotLevelLines.EquipmentNumber!= "";
}

public static void main(Args _args)
{
    PMSubJobLotLevelLines       pmSubJobLotLevelLines;
    PMCopyEquipmenttoCLR        pmCopyEquipmenttoCLR;
    FormDataSource              PMSubJobLotLevelLines_ds;

    pmCopyEquipmenttoCLR        = new PMCopyEquipmenttoCLR();

    if (_args.record() && _args.record().TableId == tableNum(PMSubJobLotLevelLines))
    {
        pmSubJobLotLevelLines          = _args.record();
        PMSubJobLotLevelLines_ds       = pmSubJobLotLevelLines.dataSource();
        pmCopyEquipmenttoCLR.CopyEquipmenttoCLR(_args);
    }
}
