low
and high will be truncated at position 255 for the first row
only. If the selection criterion is declared with the addition
NO-DISPLAY , no conversion
routine or truncation will be performed for the first row either.
If the type of the selection criterion is a
decimal floating point number that does not refer to a data type in
ABAP Dictionary, the output style retain scaling is set for the
input field of the selection screen, whereby trailing zeros are retained
in the decimal places. If there is a reference to a data type in ABAP
Dictionary, the output style defined there is used.
If the type of the selection criteria is a
packed number or a
decimal floating point number defined in
ABAP Dictionary, the property sign must be set for the type
property, so that negative numbers can be displayed on the selection
screen. This setting is only possible for domains
and not for the direct specification of a predefined type for
data elements or structure components.
If a negative number is entered on the selection screen and this
property is not set, the system rejects it with an error message. If the
columns low or high contain a negative number when the
selection screen is called, an non-handleable exception is raised.
If the selection criterion type is a decimal
floating point number that is defined in ABAP Dictionary for which
the output style "Currency Amount" is specified, only numbers
with the corresponding amount of decimal places can be entered on the
selection screen. If a corresponding ABAP data object contains a number
with too many decimal places when the selection screen is called, a
non-handleable exception is raised. If the output style is "extended
currency amount", additional decimal places can be displayed.
The sign and option columns of a selection table
declared with SELECT-OPTIONS are not related to data types in
ABAP Dictionary. For a ranges table
defined in ABAP Dictionary, these columns refer to the data elements
DDSIGN and
DDOPTION .
