Is it possible to auto TECO in background job for CU order

Hi Experts,

We need to create a custom program to auto TECO for PM orders. Now everything work well, except CU orders.

Now I use BDC to call transaction 'IW32' to update TECO for CU order, but it only works for frontground..

In the standard program, it will check the execute tcode/mode before update TECO status...

Is there any methods to auto TECO in background job?

Thanks for any advise!!!
