Dynamic field aggregation

[gcser]

Hello,

Is it possible to aggregate the values of the note-based dynamic text fields into ticket-based dynamic field? I would like a behavior like in the time accounting: in the ticket information area, there is a time sum of the notes.

Possible? Sure, anything's possible.

The question is where do you want the aggregation to be implemented? (As in, display on *THIS* page? Sum in Stats? Available in export?)

If I were to do it in display, I'd modify Kernel/Modules/ModuleThatReflectsTheOneIWantToShow.pm and sum within there.
If I were to do it somewhat globally, I'd create a sum module and extend Ticket.pm
If I just needed the information, I might export and sum in a spreadsheet or run a query against the field.

So, "Is it possible?" No, not out of the box. Anything you want to do with this field needs to be specified and determined for you.

Thanks for the info. So if I understand it right, I can do it only by modifying the code. And what is about the upgades? Will my modification preserved?

your custom modifications should be placed in the same path in otrs/Custom/Kernel/...
even though they'll survive updates there, they won't be patched if there's problems, so consider that.

Thank you, I will try it.
