payment process request format.

Hi,
Suppose i create a bank account ABC.

for ABC we have Payment document CHECK_Abc.

Check_ABC has payment format as standard_abc.

Now i submitt a payment process request .
Under payment attributes tab i select bank account as ABC,Payables document as CHECK_ABC.

Everything ok till now.
Now i select a payment process profile which has a Payment instrucion format as standard_1_abc.

Can someone tell how the system will behave now?

SInce bank account setup is telling the system to use format standard_abc and the payment process profile setup is telling the system to use the foramt as standard_1_abc.
