Hi, In an accounting journal you usually enter a line (date, amount, reason etc) and it stays there as it is so you can go back anytime and look how the line looked, or you can calculate the sum of some given users, accounttypes etc over a certain period. I was highly surprised to see in Koha these lines are not consistent but instead over time they are changing not only the original amount but also the date! For example if accountline_id 1 originally had a date of 2015-10-01 and an amount of $ 2.00 it may have changed its date to 2015-11-03 and an amount of $ 3.00. Can someone please explain what exactly happens with the money amounts and dates that are listed in the table "accountlines"? Is this described somewhere? It is absolutely necessary for us to have some kind of proof how much money was taken in cash by the library every day and also over certain periods of time. What we in fact need is an accounting journal where ALL the accounting transactions are comprehensible over time. Does such a thing exist in Koha at all? How do other libraries handle this problem? Kind regards, Michael
