• Message class: T0 - General Treasury

• Message number: 843

• Message text: The current activity has already been counterconfirmed!

What causes this issue?

The activity you want to change has already been counterconfirmed. As a

Procedure for System Administrators

If settlement activities are planned for the processing category of the
product type currently being processed, note the following:
If the confirmation process takes place in the trading activity, for
example 'Contract', and no correspondence is planned in the related
settlement activities, then the settlement activity has the same
confirmation status as the corresponding trading activity.
RESULT:
This message simply checks the counterconfirmation status. If this
already comes from the trading activity, problems may arise. Therefore,
see the information in '&FURTHER_HINTS&'.
