SAP Error Message - Details

• Message type: E = Error

• Message class: T0 - General Treasury

• Message number: 847

• Message text: Unique assignment of counterconfirmation for activity &1 not possible

What causes this issue?

Assignment of the counterconfirmation to activity &1& is not possible
as there is more than one status-relevant entry that has not been
counterconfirmed (counterconfirmation status = '3') in correspondence
table VTBKORES.
The correspondence Customizing/Standing instructions are not correct.
Upon new creation, change, reversal or settlement activities, several
status-relevant planned records are written to control table VTBKORES.

How to fix this error?

Ensure that per transaction activity only one correspondence sets the
status. Status assignment can be controlled via correspondence standing
instructions. &SYS_ADMIN&
Analyze database table VTBKORES and look at field 'SSTATUS' that should
be set per activity (field 'RFHAZU') in a maximum of one data record.
