i'm involved in a problem and I need to go to you.
I have a standard Portal aplication to manage Travels.
In a case, I need to create 2 travel in the same date, but it's common it become me an error message like this:
"Trip data for the period ....... already exists". Message nr.56146
I need to avoid this message but I don't know if it could be possible or maybe should I repair standard code or enhance it?
I need yoy knowledge!!!!
