I have to work with a device sending BootP request with the same TransactionID every time, since DHCP RFC says that

" xid 4 Transaction ID, a random number chosen by the client, used by the client and server to associate messages and responses between a client and a server."

Does it mean that TransactionID is generated randomly once and use it forever or it shoul be generated randomly on every BootP Request?

The answer is no.

Transaction ID in DHCP packets can be changed.

You can observe it even in the pair of DHCP Discovery and Request.
