BAPI Error _Cognos Reportnet

Hi All,

We are using Cognos Reportnet 1.1 for reporting. We get data from SAP BW 3.5.

The reports generated in the Cognos Reportnet are fed with data from Info cubes.

when we have about 15 info objects in the BEx query, the Cognos Reportnet is performing good. When we have more than 20 info objects the system performance is very bad and that too it is throwing a BAPI Error.

<b><i>BAPI ERROR OCCURED IN FUNCTION MODULE BAPI_MDDATASET_GET_AXIS_INFO. NO

STORAGE SPACE AVAILABLE FOR EXTENDING AN INTERNAL TABLE.</i></b>We have been facing this problem...... even for queries which do not have complex calculations.

Could anybody help me in solving out this problem.

Thanks in advance......
