End Users may receive metadata error messages (shown below) when executing any Business Warehouse report. These errors do not affect the report data at all - the results are still correct.
At this point, we are unsure what is causing these error messages. A message has been opened with SAP asking for a resolution.
In the meantime, if a user experiences the error messages, they will continue to get the error as long as they are logged in to that same portal session. Once they log out, it may or may not clear up.
