Summary :
When using SAP Transaction KB21 or KB21N to post activity allocations with activity types priced at zero, the system sends a modifiable warning message BK057. To change this behavior, users can adjust message settings in the Message Control system. Initially, modify T100S table through SM31 with entries defining message action scopes ('S', 'I', 'W', 'E', 'A') and defaults. Further configure specific message responses using Transaction OBA5 to influence how message BK057 behaves for different users or system-wide, including options for online and batch processing scenarios. This provides greater control over error handling and posting restrictions.
Key words :
