This send a message.

Look at Abap documentation, keyword message for the different types of messages and their effects. <a href="http://help.sap.com/saphelp_46c/helpdata/en/34/8e72e36df74873e10000009b38f9b8/frameset.htm">MESSAGE Syntax</a>

This is entire structure which holds message details. You would find this structure in function modules or BAPIs in the form of

Return parameters.

For e.g. BAPIRETURN1

MESSAGE ID - Gives message class

SY-MSGTY - Message type: S Success, E Error, W Warning, I Info, A Abort

NUMBER - Message number

SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4 - Message variables which hold text

If the BAPI or any FM does not return expected results, then we refer to this structure analyse the message.

It issues a message of type TYPE (Error or Information or Success or Abend) whose text is determined by the attributes of ID, Number and the variables. So if I take an example of

MESSAGE ID           00
                 TYPE      'W'
                 NUMBER 003
                 WITH       A  B C D.

will issue a message

Message with maximum length and maximum variable parts: A B C D 1234*.

You can see the messages in SE91, enter 00 for message ID and 003 for number, you will see this message with place holders (&). These place holders will be replaced by their actual values when you issue this message statement (A, B, C, D in this example).

SY-MSGID, SY-MSGTY, SY-MSGNO, SY-MSGV1, SY-MSGV2, SY-MSGV3 and SY-MSGV4 are system variables which are set in memory during the processing.
