Subject: Troubleshoot Copy of Cubes

Question

I have tried to copy several cubes on my BI 7.0 and all of them same error, so I am wondering whether I am doing something fundamentally wrong.  ~3000 records get copied, then following error is shown:
                System error in program SAPLRS_EXECPTION and from RS_EXEPTION_TO_MESSAGE
                SQL Error 0
                Unknown error in SQL Interface
                Errors in source system
After error occurs I get following message in mail:
          The error occurred in Extractor.
           Refer to the error message.
                 Procedure
             How you remove the error depends on the error message.
                 Note
          If the source system is a Client Workstation, then it            is possible that the file that you wanted to load was being edited
at the time of the data request. Make sure that the file is in
the specified directory, that it is not being processed at the
I  looked  in SM21, system logs, whenever error occurs, I see the  u201C
Database selection with invalid cursor &5&5
The database interface was called by a cursor (in a FETCH or CLOSE cursor operation) that is not flagged as opened. This can occur if a COMMIT or ROLLBACK was executed within a SELECT loop (which closes all opened cursors), followed by another attempt to access the cursor (for example, the next time the loop is executed).
I DO NOT UNDERSTAND WHEN I AM COPYING FROM CUBE, WHY SAP BW will  generate u201Cinvalid cursoru201D message. Not sure whether it is normal, i.e., not a real error,
My cube copying  (from cube 1 to cube 2) is a straightforward procedure:
a.     Select Copy from Cube 1 and create Cube 2.
b.     Create Export Data Source from Cube 1 Menu.
c.     From Cube 2 menu, Create Update rules, In update rules select DataSource as 8Cube1.
d.     Create an Info Package for 8Cube1 under Infosource/DataSource and then run the package.
Certain no of records e.g.. 3248 or so get loaded and then the error messages are generated, why?
Really appreciate any help. I tried SM37, does not give any clue. I also Tried SM50, it shows me the process, but I still cannot figure how to generate developer trace.
Since behavior is same for several cubes I tried, something else also needs to be done, I do not know what???

Answer 1

when you say copy cubes .., do you mean making a copy of the existing cube or also loading data from the same. Cursor errors usually occur for datasources.
