Effect

This declares a selection criterion selcrit for a data object dobj or a type specified in name. Selection criteria are components of a selection screen, to which are assigned a selection table in the ABAP program, as well as two input fields and a pushbutton for multiple selection.

The name of the selection criterion selcrit is limited to a maximum of 8 characters. This statement is allowed in the global declaration part of executable programs, function groups, and module pools. In function groups and module pools, the statement is only allowed within the definition of an independent selection screen. In executable programs, the statement is otherwise automatically assigned to the standard selection screen.

The statement SELECT-OPTIONS has the following effect:

  • The statement declares a selection table in the program with the name selcrit. A selection table is an internal standard table with header line and standard key. In selection tables, you can save multiple logical conditions. The content of selection screens can be analyzed in a logical expression with the predicate IN or in a similar expression of a WHERE condition in Open SQL. Selection tables have the following four columns:
  • sign of type c and length 1. The content of sign determines for every row whether the result of the condition formulated in the column is included or excluded in the entire resulting set for all rows. Evaluable values are "I" for include and "E" for exclude.

  • option of type c and length 2. option contains the selection option for the condition of the row in form of logical operators. Analyzable operators are "EQ", "NE", "GE", "GT", "LE", "LT", "CP", and "NP", if column high is initial, and "BT", "NB", if column high is not initial. For the options "CP" and "NP", the data type of the columns low and high must be c, and special rules apply for entries on the selection screen.

  • low of the data type defined after FOR. This column is designated for the comparison value or the lower interval limitation.

  • high of the data type defined after FOR. This column is designated for the upper interval limitation.
    • Two input fields with the name selcrit-low and selcrit-high are created on the current selection screen using a matching external data type in a new line at positions 35 and 60. The length of the input fields is based upon the length of the data type which is defined after FOR. The maximum length of the input fields is 255. The maximum visible length of the input fields is, depending on the nesting depth, in blocks with frames between 10 and 18. If the length is larger than the maximum visible length, then the content is scrollable.

      An output field generated automatically is displayed in the first position available to the left of the input field as a label with a length of between 20 and 30 depending on the nesting depth in blocks with frames. The output field contains either the name of the selcrit selection criterion or the selection text to which the selection criterion is assigned in the text elements of the program. If the user requests field or input help on the output field using the function key F1 or F4, the same output is displayed as if one of the input fields is chosen.

      A multiple selection pushbutton is created after the second input field. If you select this pushbutton, a dialog screen with four tabstrip control pages appears, in which the input fields are again displayed in tabular form in Table Controls. The tabstrip pages are separated based on individual value comparison, interval limitation, and settings for the column sign.

      As a user, you can select an input field with a double-click on the selection screen or use the dialog screen for multiple selection. On the selection screen, you can also choose the value for column sign. On the dialog screen for multiple selection, you can do this by selecting the respective tabstrip page. If the selection option is not equal to "EQ" or "BT", then it is displayed as an icon in front of the first input field. The color of the icon is green if the content of column sign is "I", and red if it is "E".

      The selection options "CP" and "NP" can be selected only if the first input field contains one of the wildcard characters "*" or "+". "+" masks a single character, "*" masks any character string, even an empty one. If one of these characters is entered, the selection option is automatically set to "CP". If "CP" is set, and all wildcard characters have been removed, the selection option is automatically set to "EQ" when there is a user action. This limitation does not apply within the program. During evaluation of the selection table, column low can also contain a string without wildcard characters for the selection options "CP" and "NP".

      The attributes of the elements on the selection screen can be influenced with the statement screen_options or the statement SELECTION-SCREEN.
    • The first row of the selection table selcrit is linked with the input fields on the selection screen. All rows are displayed in the dialog box for multiple selection.

      Each time before the selection screen is sent to the selection screen event ATSELECTION-SCREEN OUTPUT, the content of first row in the selection table is transported to the selection screen, with a conversion routine being executed if required. If the length of columns low and high in the first row of the selection table is over 255, the excessive content to the right is cut off. It is only possible for all rows to be transported if the button for multiple selections is selected. A conversion routine might be executed here, and rows might be cut off. Settings for the content of the input fields can be made in value_options.

      After a user action on the selection screen, the contents of the input fields and the chosen settings are transported to the first row and the header row of the selection table.

      After a user action on the dialog box for multiple selections, the contents of all input fields and the chosen settings are transported to the rows of the selection table. During these transports, the contents of character-type fields are converted by default into capitals, after which a conversion routine is performed, if required. After each transport, various selection screen events are triggered.

      If a value has been entered in the entry field for the upper interval high, the system checks whether this value is greater than the lower interval limit low following each transport and conversion routine (if performed). If necessary, an error message is sent. This check can be switched off before the selection screen is sent, using the function module RS_SELOPT_NO_INTERVAL_CHECK.
    • If selection criteria are defined in the selection include of a logical database, further additions ldb_options are necessary or possible.
    • If, in an executable program, a selection criterion is defined for a component of a node of the linked logical database, declared by TABLES or NODES, and the node in question is intended for free selection on the logical database, then the selection table is transferred (by default) to the logical database, after selection screen processing, where it is handled as a free selection. Furthermore, in this case, the input fields for the corresponding free selection are displayed directly on the selection screen. Therefore the user does not need to select the fields using the function free selection. This transfer can be suppressed using the addition NO DATABASE SELECTION.


    Notes

    • To avoid undefined system behavior, the header row of a selection table should not be changed in the program. Read access should also be avoided. Instead you should work with your own work areas, field symbols, or data references as always for internal tables.
    • If a selection criterion is supplied with data when calling up an executable program using SUBMIT, a conversion routine may be performed for the first row only, while the value of the columns 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 the ABAP Dictionary, the output style retain scaling is set for the input field of the selection screen, whereby closing zeros are retained in the decimal places. If there is a reference to a data type in the ABAP Dictionary, the output style defined there is used.
    • If the type of the selection criteria is a packed numberor a decimal floating point number defined in the 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 unhandled exception occurs.
    • If the selection criterion type is a decimal floating point number that is defined in the ABAP Dictionary for which output style "Währungsbetrag" 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 the ABAP Dictionary. For a ranges table defined in the ABAP Dictionary, these columns refer to the data elements DDSIGN and DDOPTION.
