RANGES tables
You can use the following variants of the TYPES and DATA statements to create internal tables of the same type as selection tables.
TYPES|DATA <rangetab> TYPE RANGE OF <type>.
or
TYPES|DATA <rangetab> LIKE RANGE OF <obj>.
This defines internal standard tables whose line type is a structure as follows:
SIGN(1) TYPE C
OPTION(2) TYPE C
LOW TYPE <type> bzw. LIKE <obj>
HIGH TYPE <type> bzw. LIKE <obj>
You can also use the RANGES statement to create internal tables of the same type as selection tables.
RANGES <rangetab> FOR <f>.
This statement is simply a shortened form of the following statements:
DATA: BEGIN OF <rangetab> OCCURS 0,
sign(1) TYPE c,
option(2) TYPE c,
low LIKE <f>,
high LIKE <f>,
END OF <rangetab>.
Because the statement represents an obsolete form of defining internal tables with headers and headers should not to be used, you should use above variants of TYPES and DATA statements instead of RANGES.
Tables defined in this way have the same structure as selection tables, but they do not have the same functionality. They are not part of the selection screen: No corresponding input fields are generated and these tables cannot be used as a data interface in a program <prog> called using
SUBMIT <prog> WITH <rangetab> IN <table>.
. However, you can use the above statements to create the table <table> in the calling program. The main function of these tables is to pass data to the actual selection tables without displaying the selection screen when executable programs are called.
The above tables are like actual selection tables in the WHERE clause of Open SQL statements and can be used in combination with the IN operator in logical expressions, but they are not linked to a database table. They:
are not passed like selection criteria to logical databases
cannot be used with the shortened form of selection tables in logical expressions
cannot be used like selection criteria in GET events
Obsolete version:
REPORT demo_sel_screen_tables_ranges.
RANGES s_carrid1 FOR spfli-carrid.
s_carrid1-sign = 'I'.
s_carrid1-option = 'EQ'.
s_carrid1-low = 'LH'.
APPEND s_carrid1.
SUBMIT demo_selection_screen_ldb_1 WITH carrid IN s_carrid1
VIA SELECTION-SCREEN AND RETURN.
Korrekte Version:
REPORT demo_sel_screen_tables_ranges.
DATA: s_carrid2 TYPE RANGE OF spfli-carrid,
s_carrid2_wa LIKE LINE OF s_carrid2.
s_carrid2_wa-sign = 'I'.
s_carrid2_wa-option = 'EQ'.
s_carrid2_wa-low = 'AA'.
APPEND s_carrid2_wa TO s_carrid2.
SUBMIT demo_selection_screen_ldb_1 WITH carrid IN s_carrid2
VIA SELECTION-SCREEN AND RETURN.
A selection table S_CARRID is created with reference to column CARRID of database table SPFLI. Fields S_CARRID-LOW and S_CARRID-HIGH have the same type as CARRID. The work area of the internal table S_CARRID is filled and appended to the table. Program DEMO2 is called. If DEMO2 is linked to logical database F1S, its selections screen contains the fields of selection criterion CARRID from the logical database. These fields are filled with the contents of the internal table.
