ALV DOCUMENTATION AND EXAMPLES1414 Rajago

14 of 36

Value set: SPACE, 'X'.If the calling program is a report with an ABAP/4 selection screen, setting thisparameter makes ALV read the selection screen again. If the selections are readsuccessfully, a pushbutton, via which the user can call a popup which lists the reportselections in a simple form, becomes active on the results list output by ALV.

38.

group_change_edit(1) TYPE c : Settings by user for new groupValue set: SPACE, 'X''X' = the user can enter a format option for each sort criterion in the sort/subtotalpopup, for the list format when this value changes (e.g. new page or underline).

39.No_scrolling(1) TYPE c : Does not allow scrolling of the list to the right.Value set: SPACE, 'X'.

40. Expand_all(1) TYPE c : Expand all positions

Detailed screen

40.

Detail_popup(1) TYPE c : show detail in popup.Value set: SPACE, 'X'' ' = List record detail display in full-screen mode, with top-of-page.'X' = list record detail display in popup (without top-of-page).

41. Detail_initial_lines(1) TYPE c : show also initial linesValue set: SPACE, 'X'' ' = Only fields whose contents are not initial are output in the detail view.'X' = initial field contents are also output in detail.

41.detail_titlebar(30) type c : Titlebar for detail screenValue set: SPACE, string (max.30)

` ' = ' Detail: Display' is output as the title of the detail window.'String = the string passed is output as the title of the detail window.

Display variants42. Header_text (20) TYPE c: Text for header button. Only relevant for hierarchical-sequential lists. You can toggle between display field and field list views viapushbuttons in the display variant definition popup for hierarchical-sequential lists.The views refer to the hierarchy level of the fields. This is technically a togglebetween the header table and item table fields.Value set: SPACE, CHAR (20)' ' = The header table field pushbutton text is 'Header' by default.CHAR (20) = header table field pushbutton text.

43.item_text(20) TYPE c : Text for item button. Only relevant for hierarchical-

sequential lists. You can toggle the view between the display fields and the field listvia pushbuttons in the display variant definition popup for hierarchical-sequentiallists. The views refer to the hierarchy level of the fields. This is technically a togglebetween the header table and item table fields.Value set: SPACE, CHAR (20)' ' = The pushbutton text for the item table fields is 'Item' by default.CHAR (20) = item table field pushbutton text.

44.default_ item(1) TYPE c : Items as default. Only relevant for hierarchical-sequential lists.Value set: SPACE, 'X'


15/36

' ' = The header table fields are displayed by default in the display variant definitionpopup. The user can switch to the item table fields interactively.'X' = the item table fields are displayed by default in the display variant DefinitionPopup. The user can switch to the header table fields interactively.

Colour45. Info_fieldname TYPE slis_fieldname: infofield for listoutput. A whole list recordcan be colored individually using a color code in a column of the internal output tablefor the record. Assign the name of the field containing the color code to thisparameter.Value set: SPACE, internal output table field nameThe internal output table field must be of type CHAR(3).The code must have the following syntax: 'Cxy':

C = color (all codes must start with 'C')X = color number ('1'-'9')Y = bold ('0' = off, '1' = on)

46. Coltab_fieldname TYPE slis_fieldname: Cells can be colored individually using acolor code which is contained in a column of the internal output table for the recordcontaining the cell. Assign the name of the field to this parameter.

Others47. List_append(1) TYPE c : no call screen. It is only useful to output block-listswithout specifying the above modules if the number of list blocks exceeds, or mayexceed, the maximum number specified in the block module documentation. Theseoperations are not possible for user-defined block lists.

Example code :

I_LAYOUT-f2code = ws_fcode.I_LAYOUT-zebra = 'X'.I_LAYOUT-colwidth_optimize = 'X'.I_LAYOUT-no_keyfix = 'X'.I_LAYOUT-get_selinfos = 'X'.I_LAYOUT-no_hotspot = 'X'.I_LAYOUT-no_input = 'X'.I_LAYOUT-hotspot_fieldname = FIELDNAME.I_LAYOUT-no_input = X.I_LAYOUT-no_vline = `X.I_LAYOUT-no_colhead = .I_LAYOUT-lights_condense = ` `.I_LAYOUT-totals_text = ` `.

I_LAYOUT-subtotals_text = ` `.I_LAYOUT-totals_only = ` `.I_LAYOUT-key_hotspot = X.I_LAYOUT-detail_popup = X.I_LAYOUT-group_change_edit = X.I_LAYOUT-GROUP_BUTTONS = X.

Step 6

This step is required to get the selection screen information in the report output.The prerequisite for this is to set the parameter LAYOUT-GET_SELINFOS of theIMPORTING structure.The parameters to be passed in the IS_SEL_HIDE table are:


16/36


16 of 36

o mode: 'R' = only the entries passed in the internal table IS_SEL_HIDE-T_ENTRIES

Are output in the pop up. Selection info, which the list tool read in theselection screen (when called by a report with a selection screen), isreplaced by the values passed.

'S' = the selection info which the list tool read in the selection screen of thecalling report are modified by the entries in the table IS_SEL_HIDE-T_ENTRIES.

o t_entries: Selection info table

o t_entries-mode: 'A' = output the selection info for the current table record in the infopopup.

'D' = do not output select option or SELNAME parameter selection infoin the popup.

o t_entries-selname: (only used in t_entries-mode = 'D') : Name of the select option or

parameter.

The following table fields are only used in t_entries-mode = 'A'. They contain the selectioninformation to be added.

t_entries-field: DDIC field name of the field for which selection information is to

be output.

t_entries-table: DDIC table names of t_entries-field.

t_entries-stext: Field name in info popup.

If t_entries-field and t_entries-table have been entered, this text is taken from

DDIC.

t_entries-valuf: Selection condition 'from' value (external format)

t_entries-valut: Selection condition 'to' value (external format)

t_entries-sign0: (I)nclusive (E)xclusive

t_entries-option: All values of the select options Option field allowed.

Step 6

The Table IT_SORT is populated with the sort criteria for the different fields.The caller specifies the sorting and/or subtotaling of the basic list in the internal tableIT_SORT.

This internal table has the following fields:

o spos : Sort sequenceo fieldname : Internal output table field nameo tabname : Only relevant for hierarchical-sequential lists. Name of the internal output

table.o up : 'X' = sort in ascending ordero down : 'X' = sort in descending ordero subtot : 'X' = subtotal at group value changeo group : '* ' = new page at group value change ,'UL' = underline at group value change

Step 7

The final step in the output of the report is the use of two ALV functions modules.1. REUSE_ALV_FIELDCATALOG_MERGE

Using other function module 'REUSE_ALV_GRID_DISPLAY can help us get list output inthe form of a grid and also attach logos to the report output.
