Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record." This is encoutered when I click on the Interactive Training ellipsis button in the property panel for Decision tree. After clicking the button, Tree Desktop application opens up but throws a message akin to above.<BR /> <BR /> I tried with other data sets with which I had successfully constructed trees in the past and even with them the same issue is happening..<BR /> <BR /> Any ideas?<BR /> <BR /> Thanks,<BR /> Hari Mon, 21 Sep 2009 18:38:48 GMT https://communities.sas.com/t5/SAS-Data-Science/DataRead-Error-Interactive-Decision-Tree-using-SAS-5-3-Tree/m-p/72510#M452 Hari 2009-09-21T18:38:48Z https://communities.sas.com/t5/SAS-Data-Science/DataRead-Error-Interactive-Decision-Tree-using-SAS-5-3-Tree/m-p/72511#M453 For this type of problem, please contact SAS Technical Support - great people who will be happy to help you.
