Summary :
When using BAPI_PROJECT_MAINTAIN, BAPI_NETWORK_MAINTAIN, BAPI_BUS2002_ACT_CREATE_MULTI, or BAPI_BUS2002_ACTELEM_CREATE_M to create activities or elements without specifying a control key or by selecting one for 'Internally processed operation', a system dump occurs if the related network profile defaults to a control key with 'External processing' enabled. This results in a MESSAGE_TYPE_X error with message CN893 in module CO2O_ACT_SET_DESCRIPTION due to incorrect parameter input. Ensure correct default settings in network profiles and use solution suggested in SAP Note 575692 for system stability.
