Procedure for System Administrators

If you have not made any changes to the delivered SAP programming,
contact SAP with the details of the error.
It is only possible to run one instance of the net calculation
controller (class CL_PSSC00_NET_CTRL). A second call of the method
GET_INSTANCE was made providing a different instance of the buffer
controller class (class CL_PSSC00_BUFFER_CONTROL). This is not allowed,
because only one buffer controller class is supported.
