I have the BO reports based on SAP Bex query (BW 7.1 SP9). The reports are working fine. Recently I am getting below error while trying to open the BO 3.1 infoview. Even I am unable to see the prompt screen.
A database error occured. The database error text is: (CS) "Error on NumResultCols" . (WIS 10901)
Please help me to fix this error.
