Lookup Table for Text

I really would like a lookup table for text. I have a list of errorcodes, now we only give the error number. This is not very clear to the user. So if we get an error code, I would like to be able to display a text to let the user know what the problem is. Because this list is very long, it would be very helpfull to have it in a lookup table where we can import a list. It is mentioned before, but I think it is not an any developpers list.

Idea : Table to manage error code / Software / IQAN
