Question

any one plz  tell me for what <b>SIGN</b> is used for in select-options .

Answer 1

Hi sai
This statement defines an internal table sel with a fixed structure which consists of the fields sel-SIGN, sel-OPTION, sel-LOW and sel-HIGH. While sel-SIGN and sel-OPTION have a fixed format (type character, length 1 and 2 respectively), sel-LOW and sel-HIGH inherit the type and length of their reference field f in variant 1.
... DEFAULT g ... OPTION op ... SIGN s
(xx is OPTION, i.e. one of the values EQ,NE,CP,NP,GE,LT,LE,GT); s is SIGN, i.e. one of the values I or E)
Effect
Similar to "... DEFAULT g", except that the system also proposes the specified selection option and SIGN.
You can specify the additions OPTION and SIGN in any order or omit them. The standard OPTION is EQ, the standard SIGN is I.
Example
DATA CITY(20).
SELECT-OPTIONS SO_CITY FOR CITY DEFAULT 'SAN*'
                                OPTION CP SIGN E.
On the selection screen, this results in an entry specifying that cities not beginning with "SAN" are selected.
Notes
The option op and SIGN s must be specified without quotation marks.
Addition 3
... DEFAULT g TO h
Effect
Proposes the range from g to h when the report is called.
Addition 4
... DEFAULT g TO h ... OPTION op ... SIGN s
(op is OPTION, that is, one of the values EQ,NE,CP,NP,GE,LT,LE,GT); s is SIGN, i.e. one of the values I or E).
Effect
Similar to "DEFAULT g TO h", except that the system proposes the specified selection option and SIGN.
You can specify the additions OPTION and SIGN in any order or omit them. The default OPTION is BT, the default SIGN is I.
Example
DATA WORD(20).
SELECT-OPTIONS SO_WORD FOR WORD DEFAULT 'SPRING' TO 'SUMMER'
                                OPTION NB SIGN I.
On the selection screen, this results in an entry specifying that the words between "SPRING" and "SUMMER" are excluded.
The option xx and SIGN s must be specified without quotation marks.
