Edit: Wait, are you talking about a transaction? Where would you write a transaction and not click "send"?
Yes, imagine that I opened a request order, it is open now and I set it to receive XXX BTC, but I don't deposit, I let it open, and after some Years I finally use this adress to make a deposit.
Is this possible?
I'm not sure what you're asking, but let me explain in a way which may help. The network doesn't monitor 'requests'. The network only monitors payments. If you use a wallet, or a company, or invoice or whatever to request payment from someone, the only thing that matters is that person being able to send you bitcoins. When you generate a bitcoin address correctly (done by your wallet software) that address should work forever*. You don't need to change it; even years later any sender can still send bitcoin to it.
*Bitcoin is powered by software, and this software is certainly likely to change over time meaning the way it works may change. However, developers writing for Bitcoin will usually be careful to make fundamental usage changes, like bitcoin address formats, backward compatible because they know people may not expect addresses to expire. In this case, wide announcements would likely be made.
