SCROLL LIST [horizontal]
This statement scrolls the display area of a list stored in the list buffer to the position specified
vertical. At least
one of these additions must be specified, in which all horizontal specifications refer to the columns of a displayed list. The corresponding section is displayed when the list is next displayed.
SCROLL statement is not used, a list is displayed during the initial
display, starting from the first column of the first row. If the user navigates from a details list
back to a lower list level, the list is displayed with the section in which it was last displayed. The
SCROLL statement sets a new first column, a new first row, or both. Each
SCROLL statement sets only the size specified in it, without changing the other positions.
... INDEX idx
The list level can be specified with the addition
expects a data object (which contains the list index) of type
i. The value
idx must be greater than or equal to 0. If the addition
is not specified, the list level 0 (the basic list itself) is selected when the basic list is created and the list level at which the event was raised
sy-listi) is selected when a list event is processed. If the list level specified in
idx is not available,
sy-subrc is set to the value 8.
|0||Screen section was scrolled.|
|4||Complete scrolling not possible because the list margin was reached.|
|8||Scrolling not possible because the specified list level does not exist.|
While scrolling through the list that is being created
sy-lsind), it should be noted that a
SCROLL statement is ignored prior to the first output statement, since the list does not yet exist in the list buffer.
By double-clicking the basic list, it is possible to scroll down this list in the event block
AT LINE-SELECTION to the page entered in a
selection screen. The lines on the page retain their original position with reference to the
page header by using
sy-staro. However, it is not necessary to set the column to
sy-staco explicitly, since this position is retained during vertical scrolling.
