No changes possible due to unconfirmed changes to master data

What causes this issue?

Certain changes to master data must be confirmed by another clerk.
Until they confirm the changes, automatic payments cannot be made for
this account.

System Response

On the following screen the system only displays the line item data;
you cannot change (or therefore pay) the line item.

How to fix this error?

Once the change to the master data has been confirmed, you can release
the line item for payment (when editing the payment proposal).

Procedure for System Administrators
