The requirement is to have approval for a payment batch prior to formatting it. R12

For example,. they would like the payables processor to build the batch, print the checks and confirm the batch, and have the manager remove invoices from the batch after it is built (if required) and then format or approve the batch.  

I have thought of two ways of doing this.  

1)  Create 2 responsibilities.  1 that allows the user to do everything but format the batch.  1 that allows the user to format the batch.  I have not been able to get this to work.  I have remove the function "Payment Batches Format" but I am still able to format the batch.  

2)  Add some type of approval after batch creation, prior to format.  Unless anyone knows different, this would be a customization.
