In this activity you define the fields for dual control in the customer/vendor master records.
If you define a field in the customer/vendor master record as "sensitive", the corresponding customer/vendor account is blocked for payment if the entry is changed. The block is removed when a second person with authorization checks the change and confirms or rejects it.
The alternative payee field has been defined as sensitive in the Customizing table. If the accounting clerk responsible changes the entry in this field in the customer/vendor master record, the account is blocked for the payment run until a second person with authorization confirms the change to the master data.
Define the required fields as sensitive. You can choose the fields using the possible entries button.
