Dear:
              You can map external transactions to  posting rules within a transaction type. After that  assign each bank key and bank account combination to the transaction type that should be used for processing statements for that account. If you want different external transaction mappings for different account IDs, then you need to create different transaction types and assign each account to the relevant transaction type. Since the TT are assigned to the account numbers, you can have different TT for accounts with the same bank key. 
To have different posting rules for debit and credit, you don't need using separate transaction types: the assignment of a posting rule to external transaction is done separately for + and - signs, so you can assign 2 different posting rules to an external transaction, one for debit and one for credit.
