Hi there,
I am a contractor working with a client who is using SAP. I'm having some difficulty understanding some of the terminology. Can anyone tell me what a Bank Country Key means? And what the Bank Country Key is for the UK?
My client also asks for a Bank Key - is this a separate key? If so, what does this translate to? Is it a swift/bic code, or a sort code?
Finally, my client asks for a Bank Control Key - what does this mean?
I hope someone can help! 
Best regards,
Soph
