Ciao a tutti,
stavo cercando tramite codice di eseguire una query mdx su un cubo SAP.
Riesco senza problemi a creare una connessione IBIConnection, e da questa connessione riesco ad estrarre senza problemi l'oggetto IBIOlap.
Quando però tento di esegure una query mdx e di mettere il risultato in un oggetto IBIDataSet utilizzando il metodo execute dell oggetto IBIOlap ho il seguente errore:
