Cannot activate ODS request, Previous request (with error) not yet uploaded

Hi All!

Pls help me with this problem. I had a request number for my ODS loading which is 567. When i did the activation for this request, it was terminated, and it showed me "Request 556 has still not been uploaded. First Upload Request 556". However, request 556 has encountered error yesterday during a system dump. How can i cancel that request? Is there such thing as uploading a faulty request? I tried marking it as red, but the same error.

Pls advise what to do. Thank you in advance for your inputs.
