I have a very weird problem with a report I have developed:
- I have a HANA server with a view created. I can view all the data without problems.
- I have developed a Universe from this view. The universe has developed with my laptop and I haven't got any problems. (the connection to hana is a relational JDBC one)
- I have developed a report from this universe with Webi Rich Client on my laptop and I can view the report without problems.
Now, the problems come when I try to execute the report from the BI Platform (4.1 SP6). The report gives this generic error when opening it:
An intern error has happened calling the API 'processDPCommandsEx'. (Error: ERR_WIS_30270) (Error: INF )
If I try to refresh the data of the report, the error is this: while trying to invoke the method com.sap.connectivity.cs.core.DbParameterSet$DomainParameterSet.getFunctions() of a null object returned from java.util.Map.get(java.lang.Object)
Another clue is that If I try to open the Universe from the IDT installed on the BI Platform server, the connection gives me the same error: while trying to invoke the method com.sap.connectivity.cs.core.DbParameterSet$DomainParameterSet.getFunctions() of a null object returned from java.util.Map.get(java.lang.Object)
So at the end it seems a connectivity problem with the JDBC driver installed on my BI Platform Server, but I have tried like 15 diferent versions of the ngdbc.jar driver and none makes the report work.
Any tips? I'm getting really frustated with this problem.
Thanks to all!
