Message lists

One single operation can produce multiple messages. In this case, HCD displays a message list. You can then:

Use the Explain message action from the context menu (or action code e ) to get an explanation of the message.

Use the Delete message action from the context menu (or action code d ) to delete a message from the message list.
Select Save messages from the Save action bar to save the displayed messages in the corresponding message log file.

The messages in Figure 1 are sorted by severity, which is indicated in column Sev:

Messages with severity code T (terminating) and E (error) require your intervention before you can continue to work with HCD.
For warning messages there are two severity codes S (severe warning) and W (normal warning). Both severities let you finish the current HCD function. However, you should carefully consider the warnings and it is recommended to remove the reason of the messages.
Messages preceded by severity code I are informational messages.
