Hi,
>>First, let me see if I have the most critical problem well understood... >>you NEVER lose any records, but rather have some records that fail to be >>indexed until you do a REINDEX. Is that correct?
Hmm.. I ever tried to delete the sales no tag, but I still not see the missing records.

As I know, my client ever try to preview sales report during the business working time to time. Will report generating cause corruption?

Thank you
