Mining erasable itemsets is a problem derived from production planning of manufacturing industry. Previous erasable-itemset mining methods only focused on static product databases. In this paper, we propose a method to solve the maintenance problem of erasable itemsets for product deletion. It partitions all the itemsets into four cases according to whether they are erasable in the original database and in the deleted products. Each case will take the corresponding process to reduce the number of times required for rescanning the original database. At last, experiments are made to verify the proposed approach.
