ABAP Syntax Starting with “R”


Home »ABAP Syntax » ABAP Syntax Starting with “R”


Syntax Starting with “R”

RAISE for Class-Based Exceptions

Raises an exception.

Syntax

RAISE EXCEPTION TYPE <class> | <ref>.

Terminates processing and raises an exception of the exception class <class>. If the reference variable <ref> points to an object of an exception class, <class> can be specified instead of TYPE.




RAISE for Exceptions of Function Modules and Methods

Raises exceptions.

Syntax

RAISE <except>.

Only occurs in function modules and methods. Terminates processing and raises an exception <except> defined in the interface.

RAISE for Events

Triggers events in ABAP Objects.

Syntax

RAISE EVENT <evt>.

Only occurs in methods. Triggers the event <evt> and calls all registered handler methods.

RANGES

Declares a RANGES table.

Syntax

RANGES <rangetab> FOR <f>.

Declares a RANGES table for the field <f>. A RANGES table has the same data type as a selection table, but is not linked to input fields on a selection screen.

READ for Files

Reads a file.

Syntax

READ DATASET <dsn> INTO <f>
[MAXIMUM LENGTH <maxlen>]
[ACTUAL LENGTH <len>].

Reads the contents of the file <dsn> on the application server to the variable <f>. The amount of data can be specified using MAXIMUM LENGTH. The number of bytes transferred can be written to <len> using ACTUAL LENGTH.

READ for any Internal Table

Reads a line of an internal table.

Syntax

READ TABLE <itab>  FROM <wa>
|WITH TABLE KEY <k1> = <f1>… <kn> = <fn>
|WITH KEY = <f>
|WITH KEY <k1> = <f1>… <kn> = <fn>
INTO <wa> [COMPARING <f1> <f2>… |ALL FIELDS]
[TRANSPORTING <f1> <f2>… |ALL FIELDS|NO FIELDS]
|ASSIGNING <FS>
|REFERENCE INTO <dref>.

This statement reads either the line of the internal table with the same key as specified in the work area <wa>, the line with the key specified in the TABLE KEY addition, the line that corresponds fully to <f>, or the one corresponding to the freely-defined key in the KEY addition. The contents of the line are either written to the work area <wa>, or the line is assigned to the field symbol <FS>. If you assign the line to a work area, you can compare field contents and specify the fields that you want to transport.

READ for Index Tables

Reads a line of an internal table.

Syntax

READ TABLE <itab> INDEX <idx>   INTO <wa>…
| ASSIGNING <FS>
| REFERENCE INTO <dref>.

The line with index 7 is read. The result is specified as with any internal table.

READ for Lists

Reads the contents of a line from a list.

Syntax

READ LINE  <n> [INDEX <idx>] [OF CURRENT PAGE|OF PAGE <p>]
|CURRENT LINE
[FIELD VALUE <f1> [INTO <g1>]… <fn> [INTO <gn>]].

Reads either the line <n> on the current or specified list or page, or the last line to have been selected by the user. The addition specifies the fields that you want to read, and the target fields into which they should be placed. The entire line is always placed in the system field SY-LISEL, and the HIDE area is filled for the line.

READ for Programs

Reads ABAP programs into the program library.

Syntax

READ REPORT <prog> INTO <itab>.

Copies the lines of the program <prog> into the internal table <itab>.

RECEIVE

Receives results from an asynchronous function module call.

Syntax

RECEIVE RESULTS FROM FUNCTION <func> [KEEPING TASK]
[IMPORTING … fi = a i… ]
[TABLES    … fi = a i… ]
[EXCEPTIONS… ei = r i… ]

Occurs in special subroutines to receive IMPORTING and TABLES parameters from function modules called using the STARTING NEW TASK addition
