You can apply internal table for create dynamic where clauses.

Example

DATA i_where(100) OCCURS 0 WITH HEADER LINE.
APPEND ’vbeln LIKE ’’%1’’’ to i_where.
APPEND ’matnr LIKE ’’%M’’’ to i_where.

TABLE lips.
DATA i_lips TYPE TABLE OF lips WITH HEADER LINE.
SELECT * FROM lips INTO TABLE i_lips
      WHERE werks = ’1000’
        AND (i_where).

Above Example is look like:

TABLE lips.
DATA i_lips TYPE TABLE OF lips WITH HEADER LINE.
SELECT * FROM lips INTO TABLE i_lips
      WHERE werks = ’1000’
        AND vbeln LIKE ’%1’
        AND matnr LIKE ’%M’.  

If you want to copy file on PC windows, you can use function "WS_FILE_COPY".

Example

*&---------------------------------------------------------------------*
*&      Form  COPY_FILE
*&---------------------------------------------------------------------*
*       text
*----------------------------------------------------------------------*
*      -->PAR_SOURCE       text
*      -->PAR_DESTINATION  text
*----------------------------------------------------------------------*
FORM copy_file USING    par_source
                        par_destination.  

When you want to display value of filed as checkbox in ABAP report, you can use WRITE statement by using option "AS CHECKBOX".

Example

DATA: ch1(1) TYPE C,
      ch2(1) TYPE C VALUE ’X’.
WRITE: / ’Checkbox 1 ’, ch1 AS CHECKBOX,
       / ’Checkbox 2 ’, ch2 AS CHECKBOX.

In ABAP/4, you can specify table name in SELECT statement by dynamically.

Example

DATA table_name(10) TYPE C.
DATA num_rows TYPE I.
table_name = ’BKPF’.
SELECT COUNT( * ) FROM (table_name) INTO num_rows.
WRITE: ’Table Name ’, table_name, ’have rows ’, num_rows.

The statements that same keyword can be chained by colon (:). Between the statements separated by ",". When you apply this method, ensure that the chained statement ended by ".".

Example

Normal Statement

PARAMETERS p1(10) TYPE C.
PARAMETERS p2 TYPE D.

Chained Statement

PARAMETERS: p1(10) TYPE C,
            p2 TYPE D.

Normal Statement

WRITE ’First’.
WRITE ’Second’.
