Hi Manish,
Thanks for the recommendation to work with a developer to find out the cause of this issue.
Yes, I had removed another entry (from '005' to '902') earlier and TO created with correct RF Queue assigned ('005'). It started to assign incorrect queue when I added a new entry (from '005' to '922').
I have seen this happening few times before and had done something else to bypass this issue, but not this time. If there is no other solution I have to work with ABAP'er to control this through code.
I appreciate your message.
Regards,
Khanh
