How can I set up a responsibility to adjust transactions without having access to Transaction menu

Hi All,

I have a responsibility that should not have access to enter invoice/transactions but they need to adjust invoices already in the system. I have the AR_TRANSACTIONS_GUI menu excluded from the responsibility but this means the 'Adjust' button is greyed out when they go to Collections / Account Details.

Is there a way around this....it's an audit requirement not to be able to enter invoices !

Any help would be appreciated.

Thanks

Sue
