Hi,
Check this notes on top-of-page.
TOP-OF-PAGE Code
The TOP-OF-PAGE code is copied into every generated report and appears at TOP-OF-PAGE just before the instructions for output of the page header. If this code includes WRITE statements, then the output will appear in the list before the page header that is created by the query. If the list is printed with a standard page header, then the output appears between the standard page header and the page header created by the query. You should note that these additions to the output cannot be displayed by the layout display in the query maintenance component.
When outputting using the SAP List Viewer, the code at TOP-OF-PAGE has no significance.
The TOP-OF-PAGE code is maintained by selecting the symbol Code. Choose TOP-OF-PAGE using the F4 help. Any ABAP statements may be used in the code. Any data objects may be accessed. However, it is better to restrict to the following objects:
Parameters from the InfoSet and the logical database
Selection criteria for the InfoSet and the logical database
global data from the DATA code
Fields in logical database tables or additional tables and additional fields do not have a defined value at this point.
The %HEAD variable can be used to specify which page header should be output. This variable is available in the standard settings and takes one of the following values:
AAA
Output at END-OF-SELECTION (before the list is output)
GGG
Output the basic list
Txx
Output the statistics xx (xx=01-99)
Rxx
Output the ranked list xx (xx=01-99)
WWW
Output the conversion table
ZZZ
Output at END-OF-SELECTION (after the list is output)
The value of the %HEAD variable may be queried but may not be changed, since it is an internal runtime system variable.
The use of TOP-OF-PAGE code allows the standard page header to be extended. However, it is important to note that if this is done then the changes will take effect on all queries that work with this functional area.
****reward points if helpful.
all the best
