Im trying to construct a decision tree in Interactive Training mode (SAS EM 5.3 and Tree Desktop application).
Till yesterday, I had no issues in building trees/pruning etc, but recently I started getting the following error "Unable to read observation 1 from the model data set. 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.
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..
