After synchronization, CATS notebook displays the messages that were created by SAP R/3 for the transferred data. These messages have different message types:
You can use the SAP enhancement MYCATS04, to filter certain message types so that that only error messages are displayed in the message area in CATS notebook, for example. This SAP enhancement also enables you to display customer-specific messages in the message area in CATS notebook.
You cannot use this SAP enhancement to influence the display of error messages (E). Messages of this type are always displayed in the message area in CATS notebook.
