Custom AIF operation in Microsoft Dynamics AX 2009

Today let's try to create custom operation on generated by AX AIF Wizard service code.

1. Create new method and write code. 

2. Find you service object in AOT and Add service operation. Select checkbox and press OK.

3. In Visual Studio  add reference to your service.

4. Now can call your custom AX method  in C# code.

private int GetEmplVacationDays(string _emplID, DateTime _from, DateTime _to)
{
    var emplServiceClient = new goEmplTableServiceClient();
    int ret;
    
    try
    {
        ret = emplServiceClient.calcDays(_emplID, _from, _to);
    }
    catch (Exception xException)
    {
        ret = 0;
    }

    return ret;
}
