error while exporting .epa file to transport request

Hi Experts,

I got a problem while exporting the transport package to transport request. In the last step of the export process, I am getting a status message as

"Could not release BIPortalContent.epa to transport request ABCD900005; consult your system administrator."

Can anyone help me in diagnosing this problem? I could not get a solution for this and due to this, the export process is stopped. I have tried with different transport requests and different authorizations, but result is the same.

I would appreciate your help in resolving this issue.

Thank You.

Regards,
