slis_layout_alv documentations

A layout is build for the report output list description USING the internal table declared above (I_LAYOUT).
Output list description structure.
The parameters are described under the following heads:
-          Display options
-          Exceptions
-          Totals
-          Interaction
-          Detail screen
-          Display variants (only for hierarchical-sequential lists)
-          Color
-          Other
The layout table is of type slis_layout_alv_spec and has the following fields

1. Colwidth_optimize (1) TYPE c: This parameter optimizes the length of the different columns in the output. The width of the different col. now depends on the max. Length of the data in the column.
Value set: SPACE, ‘X’
‘X’ = optimizes the column width so that all contents are displayed completely.

2. No_colhead (1) TYPE c: This parameter suppresses the column headings Value set: SPACE, ‘X’. ‘X’ = column headers are not output

3. No_hotspot*(1) TYPE c :  The headings of the report output are not output as hotspot.  Value set: SPACE, ‘X’. ‘X’ = column headers are not output as hotspot

4. Zebra*(1) TYPE c : The report is output in the striped pattern.   Value set: SPACE, ‘X’.  ’X’ = striped pattern (e.g. for wide lists)

5. No_vline (1) TYPE c: The report output contains columns only separated by space and no lines.  It is not relevant for: hierarchical-sequential lists and multiple-line lists. Value set: SPACE, ‘X’. ‘X’ = columns separated by SPACE

6, No_min_linesize(1) TYPE c : The report  line size is equal to the width of the list. It is not relevant for block lists.

7. Min_linesize LIKE sy-linsz: The report output contains a minimum possible length of line. If initial min_linesize is set to 80 by default, then this parameter is used to customize it. The prerequisite for this is that the parameter no_min_linesize should be ‘ ‘.
Value set: 0, 10 – 250
If the list is wider, the format uses the list width (maximum 250 or MAX_LINESIZE (if > 0)).

8. Max_linesize LIKE sy-linsz: The default max. Linesize is 250. To change this default value, this parameter can interactively-define the maximum list width setting.

24. Subtotals_text(60) TYPE c : Texts for subtotals Value set: SPACE, string (max.60) ’ ‘ = In the first column of subtotal records, the subtotal is indicated by an appropriate number of ‘*’ by default. If the first column is not a subtotal criterion, the string ‘Total’ is output after the asterisks, if the column is wide enough.

Interaction

25. Box_fieldname TYPE slis_fieldname: Fieldname for checkbox in the report output.
