MESSAGE - msg
Other versions: 7.31 | 7.40 | 7.54
Syntax
... { tn }
| { tn(id) }
| { ID mid TYPE mtype NUMBER num }
| { oref TYPE mtype } ...
Alternatives
3. ... ID mid TYPE mtype NUMBER num ...
4. ... oref TYPE mtype ...
Effect
msg
specifies a message from the database table
T100 either by specifying id
and n
directly or by using the content of the data objects mid
and num
for the message class and the message number. Alternatively, an object reference variable oref
is specified whose
dynamic type implements the interface
IF_T100_MESSAGE. One of the possible message types
"A", "E", "I", "S", "W", or "X" must be specified, either by specifying t
directly or as content of the data object mtype
. This controls the
behavior of the message.
If the specified message is not found for the logon language of the current user, a search is made in the secondary language (profile parameter zcsa/second_language) and then in English. If it is still not found, the specified message type, message class, and message number are used as short text in uppercase letters and separated by a colon ":".
The system fields of the statement MESSAGE
are always supplied with the specified values.
Note
The maximum length of a message is 269 and is determined from the short text of the message in the database table
T100 (with a maximum of 73 characters) including
up to four single-character placeholders &. These placeholders can
be replaced by strings with a maximum of 50 characters using the addition WITH
).
Alternative 1
... tn ...
Effect
t
and n
are used to specify the single-character
message type and the three-digit message number directly in a row (static short form). The message class
must be specified with the addition MESSAGE-ID
in the statement that introduces the program.
Example
Displays the short text of the message with the number 014 from the message class SABAPDOCU as an information message.
REPORT rep MESSAGE-ID sabapdemos.
...
MESSAGE i014.
Alternative 2
... tn(id) ...
Effect
The same applies to t
and n
as to the static short
form. In the static long form, the message class is specified directly in parentheses using id
.
Notes
-
Specifying the message class explicitly overrides the addition
MESSAGE-ID
of the statement that introduces the program. -
Specifying the message class in parentheses does not signify here that the content of
id
is used. In fact, the message class is used that has the name that was specified directly withid
.
Example
As in the example for alternative 1, with the message class specified explicitly.
REPORT ...
...
MESSAGE i014(sabapdemos).
Alternative 3
... ID mid TYPE mtype NUMBER num ...
Effect
The message class, the message type, and the message number are specified as content of the data objects
mid
, mtype
, and num
(dynamic form). mid
and mtype
expect character-like
data objects that must contain the message class or the message type in uppercase letters. Invalid message
types raise a non-handleable exception. num
expects a data object of the type n
and length 3.
Note
Specifying the message class explicitly overrides the addition MESSAGE-ID
of the statement that introduces the program.
Example
As in the example for alternative 2, with the message and the message type specified dynamically.
DATA: mid TYPE sy-msgid VALUE 'SABAPDEMOS',
mtype TYPE sy-msgty VALUE 'I',
num TYPE sy-msgno VALUE '014'.
MESSAGE ID mid TYPE mtype NUMBER num.
Alternative 4
... oref TYPE mtype ...
Effect
For oref
, an object reference variable can be specified which, when the statement MESSAGE
is executed, points to an object whose class implements the system interface
IF_T100_MESSAGE. This in turn contains the
component interface
IF_MESSAGE. mtype
expects a character-like data object containing the message type in uppercase letters. oref
is a
functional operand position.
The statement MESSAGE
analyzes the components of the structured attribute
T100KEY of the interface IF_T100_MESSAGE in the referenced object. The
message class is taken from the component MSGID and the message number from the component MSGNO. If
the components ATTR1 through ATTR4 contain the names of attributes of the object, the placeholders "&1"
through "&4" and "&" of the short text or "&V1&" through "&V4&" of the long
text of the message are replaced by the content of these attributes according to the rules of usage
given by the additions WITH
in
message_options. If one of these components does not contain an attribute name, the character "&" is added to the content at the beginning and end, thus replacing the placeholder.
Notes
-
In this variant, the additions
WITH
andINTO
inmessage_options
are not allowed. -
If field symbols or formal parameters of the generic type
any
ordata
are specified fororef
, then the syntactically identical variantMESSAGE text
is used. - This variant is mainly intended to be used with exception objects. If a global exception class implements the interface IF_T100_MESSAGE, then the components of the structure T100KEY are filled in accordance with the definition of the associated exception text when such an exception is raised in the interface method GET_TEXT (which is implemented in the superclass CX_ROOT). In local exception classes, the components must fill themselves. To do this, do not redefine the interface method GET_TEXT, but use the instance constructor instead.
-
For compatibility reasons, this variant can still be used for classes that only implement the interface
IF_MESSAGE. In this case, the interface methods GET_TEXT and GET_LONGTEXT are called automatically in
the referenced object and their return value is used as the short text or long text of the message.
In this case, the system fields
sy-msgid
andsy-msgno
are not filled specifically. The root class of all exception classes, CX_ROOT, implements the interface IF_MESSAGE. In exception classes that do not implement the interface IF_T100_MESSAGE, the interface methods GET_TEXT and GET_LONGTEXT get the exception texts of exception objects stored in OTR (Online Text Repository), which then can be issued by using the variant of theMESSAGE
statement as a message.
