The "Messages" screen registers and changes messages. A message is an asynchronous exchange of information, for example by email. The entry fields have the following meaning: - "Number": The unique number that identifies the message. - "Category": The category of the message. The category allows deleting duplicate messages or sending only the last message of a specific category for an object ID. - "Priority": The numeric priority with which the message is processed. Zero means neutral, a negative value means bulk and a positive value means urgent. - "Finished": The message has been processed when this box is checked. - "Translate Subject": When checked, the subject of the message is translated to the specified language before delivery. - "Translate Content": When checked, the content of the message is translated. - "Recipient": The email address of the recipient. - "Name of Recipient": The name of the recipient. - "Sender": The email address of the sender of the message. - "Name of Sender": The name of the sender. - "Subject": The subject of the message. - "MIME Type": The [[Invantive Estate/Subjects/Advanced/MIME Types|MIME type]] of the message, for example `text/html`. - "Language": The reference to a language, used for the translation, as registered in [[Invantive Estate/Subjects/Advanced/Languages|Languages]]. - "Last Message": The last message that occurred in an attempt to process the message. - "Date First Try": The point in time of the first attempt to process the message. - "Last Try": The point in time of the last attempt to process the message. - "Next Try": The earliest point in time of the next attempt to process the message. - "Do not Deliver After": The system time after which the message can be removed and is no longer delivered. - "Number of Tries": The number of completed attempts to send the message. - "Parent": The table alias of the table that contains the object to which the message is linked.
