Recently, I am using the enterpriser miner 15.1 for association analysis of my transaction data. I have 3 dataset with the same structure and I can run association analysis successfully on previous 2. However, I failed on the last one which report a error 1016. Then, I have rechecked the role of that data and it is correctly set to transaction. How can I tackle this problem?   There are only two input used for the association node. First one is Invoice which is the invoice id and the role is ID, second one is StockCode which is the product ID and the role of it is target.   Previous 2 are having over 30000 observations, and the last one only contains around 2000 observations.      Here is the log file: ----- Potential 1 item sets = 973 ----- Counting items, records read: 2176 Number of customers: 71 Support level for item sets: 1 Maximum count for a set: 13 Sets meeting support level: 973 Megs of memory used: 0.51 ----- Potential 2 item sets = 472878 ----- Counting items, records read: 2176 Maximum count for a set: 8 Sets meeting support level: 115018 Megs of memory used: 30.72 ----- Potential 3 item sets = 10730963 ----- Counting items, records read: 2176 Maximum count for a set: 5 Sets meeting support level: 10434731 Megs of memory used: 717.30 Error: Out of memory.
