Bank Reconciliation for 1st time implementation

Hi

We are implementing SAP for old company who used to prepare BRS manually. Now they have some tailor-made old accounting system.

In SAP, there are two types of BRS:

1. Manual FF67 where data needs to be entered manually / through BDC.

2. Electronic BRS (through FF.5) where we directly upload the data in BRS

Now since they are 100% new to SAP, i am not understanding which of the above BRS i should suggest. Its because they are not willing to do manual BRS since updating data in FF67 would be not possible.

For E-BRS i am not comfortable since they are 100% new to SAP.

So is there any third way to do BRS. What do other company do for BRS when they go on SAP for the 1st time.

Please help
