Change company in Dynamics AX 2009

Hi, 

In Microsoft Dynamics AX Axapta, sometimes, we can to insert/update/delete records in different companies or insert/update/delete according to the company we are... 

In Dynamics AX, exists the "changeCompany" function, that allow us to do that easily.

Here's an example:

static void main()

{

    CustTable custTable;

    ;

    //Assume that you are running in company 'aaa'.

    changeCompany('bbb') //Default company is now 'bbb'.

    {

        custTable = null;

        while select custTable

        {

            //custTable is now selected in company 'bbb'.

        }

    }

    //Default company is again set back to 'aaa'.

    changeCompany('ccc') //Default company is now 'ccc'.

    {  

        //Clear custTable to let the select work

        //on the new default company.

        custTable = null;

    

        while select custTable

        {

            //custTable is now selected in company 'ccc'.

        }  

    }

    //Default company is again 'aaa'.

}
