Hi Kim,
It appears that the
rateScope you are getting is already at the
ACCOUNT level. This indicates that there are other requests being made to the same account at the same time. I would recommend that you review any processes or users that are also making calls to the same exact account at a given time to avoid the error.
However, should you find out that no other users or processes are making calls, you may send to me the complete SOAP request and response and you may reply to me via the Reply privately to author option.
Thanks and regards,
Peter
