How to reconcile one bank account to multiple business units

Summary:

The client has a requirement to switch from a shared service model to a service provider model. This will involve making supplier payments from a single bank account. The bank account will contain multiple assignments for the business units that will be making payments from the account.

Prior to making this change, bank statement reconciliation is straightforward, as each business unit has it's own bank statement. The Cash Manager can open the bank statement lines awaiting reconciliation and search for the list of available transactions with a matching business unit.

However, it would be useful to understand how the reconciliation will work if there is only one bank account with bank statement lines for multiple business units.
