BDC Ok Code required for Dropdown.

Hi,

I need to develop a BDC program for transaction CRM_DNO_MONITOR. It should select the given transaction and change the user status from Status Tab. There is dropwdown button for changing the user status. When this button is clicked it displays a drop down list. We can select the required option from this list. I have done BDC recording for this. But when I process the recording it does not change the status. I also processed the recording in foreground mode and found that the OK Code for this dropdown button is 10MAIN_ENTER. But it is not working.

Is there another OK Code I shall use or Is there any other way to change the status of transactions? I need to change it for 1000 transactions.

Thanks in advance...
