Hi All, I am new to otrs, and am using it for about a month now. I like the tool! However, I would like to be able to get a report over a certain period, with the total sum of worked time per customer. In SQL I would do (SQL statements are in CAPITALS): SELECT customer_id,count(tn) AS tickets, sum(time_unit) AS worktime FROM ticket LEFT JOIN time_accounting ON ticket.id = time_accounting.ticket_id WHERE tn LIKE "2009%" GROUP BY customer_id This will give me a list with customer, number of tickets per customer, and total working time per customer, for all tickets in 2009. This selection would be preferrably be adjustable. This list I can use to bill my customers The customer wants to know where he/she pays for, so I'll do: SELECT * FROM ticket LEFT JOIN time_accounting ON ticket.id = time_accounting.ticket_id WHERE customer_id LIKE "ACME" Where ACME is the customer name. Is there a way to do this? I use LDAP as my customer backend, and version 2.2.7 of OTRS. Thanks for any reply, Marcel
