Bank Key, Bank Number and SWIFT code

Question

Hi expert,
I would like to consult your expertise on the following issues: Bank Key, Bank Number and SWIFT code.
In Country Field Check, OY17, If I select the bank key (section key for bank directory) options 4, assigned externally; then in FI01 bank key data creation, my bank number (in control data section) can be freely defined.
If in OY17, my bank key option is 1, bank number.  Then, during FI01 bank data creation, my bank number must be same with bank key.
My question is that:  I would like, in OY17, selection option 4, but I would like to have some clarifications on FI01 bank creation as well as electronic bank statement ( section of: Assign bank account accounts to transactions types):  In the section of Assign bank account accounts to transactions types, I need to fill in bank key+bank account and transaction type.
My Questions: during MT940, electronic bank statement (EBS), since I set bank key + bank account, what control data (in FI01 screen) that SAP will use for automatic EBS?  Bank number or SWIFT code?
Besides that, I am not quite understand statement by SAPPress book, Quick Reference Guide Financial Accounting with SAP - Chapter 7 Banking, as follows:
If you use the SWIFT code as bank key in a specific country, we strongly recommend that you set the bank data flag on the further checks section in OY17.  This ensures that the system automatically performs the formal control on the SWIFT code entered in the SWIFT code field (BNKA-SWIFT), and not on the SWIFT code entered in bank key.
Thanks in advance

Bank key is a country unique number in the US it is called the ABA routing number.
The account ID is a user definable field that allows you to "name" your bank accounts at your bank using any convention you prefer.
Bank master data means all the data related to a particular BANK .examole HDFC all the information related this particular bank.
House bank master data  it is related all your bank master data.Example,Hdfc,ICICI,Axis ,BOB  etc.
