I get an error 3251 in aldelo how do i fix it. Posted on December 6, 2016March 30, 2021 by Bulldog Tech This error refers to database corruption. Perform a backup first then Try using the compact database feature. Another option is to use the jet compact utility (advanced users) usually performed by a technician. Post navigationPrevious post: When a server using a “staff bank” closes out the staff bank, the closing report will ask for an amount of cash due from server. This amount, as I understand it, is the amount of cash sales, minus any gratuities. However, sometimes the gratuities are larger than the amount of cash sales, and the report states an amount that is owed to the server. My question is this – does the POS automatically subtract this amount owed to the server from the total cash on hand?Next post: What does the “compact database” button form the back office do?
