So that you know what the original amount of the fine is/was.  This is especially useful in an ongoing overdue fine, for example.  The patron may have some, but still has the book.  So the script can look at what the fine is supposed to be, and what it was last time the script ran (the amount column) then add the difference to both the amount and amountoutstanding columns. (Since we can't guarantee that the script is run once, and only once, a day.)

Thank you sir,

Can you please help me understand these tables?
What is the purpose of the 2 tables 'accountlines' and 'account_offsets'?

account_offsets is a child of accountlines, which allows 1 accountlines row to have multiple account_offsets, and the 'account_offsets.amount' is the total amount debited/credited. What exactly is the 'amountlines.amount'?
In my database, there is an accountlines row which has 3 account_offsets rows linked, 2 of them credit $5, and 1 debits $10, making the amountoutstanding=0, which is expected. But accountlines.amount stores 10. Why is that so?

Thanks in advance

Amount is the original amount of the fine/invoice, and amountoutstanding is the remaining amount after receiving / sending some sort of payment.  There should be another row in that table, and a link in the accountoffsets table, of those two columns aren't the same, but that's probably more than you wanted to know.

Hello everyone,

I am currently working on a project on Reports Management and Decision Support System for my institute library that uses Koha as it's ILS. I have a doubt in understanding what is the difference between the fields 'accountlines.amount' and 'accountlines.amountoutstanding'?

Could someone help me out with this?

Thanks in advance.
