My friend transferred money to me across the bank, and I received a message that the application for transfer should be based on the actual funds. What does that mean?

When transferring money through a bank, the transferor can send a transfer message to the transferee's mobile phone at the same time. This message is the notification message of the transferor, which can be compiled artificially and its content does not represent the actual situation. Therefore, some banks will send a notice of transfer application at the same time of transfer, reminding the transferee to confirm by himself, subject to the actual funds received.
