F-02 Data Upload using UI Path

In F-02 Tcode i tried to data load using UI path recording. I used web recording for data load. I entered 40 and 50 key items. After that i clicked on “Simulate” from the top menu. Cost center automatically cleared and displaying error message as cost center is empty. when i select cost center from the space bar option, “simulate” is working without any error.

This cost center problem is coming only when we are creating recording only.

Please anybody assist me to clear this problem.
