Hi,
the standard rule set activity TM_MAINTAIN_EXEC_INF (which is based on FM /SAPTRX/TMS_CHANGE_EXEC_INF) can be used to propagate event messages to a related freight document (TOR) in SAP TM. This will create or update entries in the node EXECUTIONINFORMATION of the TOR object. If you only want to propagate these events from SAP EM to SAP TM, the rule set activity can be used straightforward. You can check one of the delivered multitask activities, e.g. ODT30_TO_DEPART, how this can be done.
Best regards, Daniel
