Report Layout is not same for excel and odf

Question

I have a footer created in my report layout
When i export the report to pdf it displays at the end of the page but when I export it to an excel
the footer displays just below my report data and not at the end
Should there be a different layout for pdf's and excel's

Answer 1

The order of extracted records can no be assumed to be constant, any SQL optimizer can change behavior, even without any wide upgrade, but a single database or kernel patch as well as many operation of database administrator can change the order, as well as a change of user behavior, if they fill now another field in selection. So it is good practices to always sort (or use sorted type) internal table extracted or use a ORDER BY clause (provided there is an index in database, else do not)
Read online documentation of SELECT statement clause ORDER BY
The order of the rows in the result set refers to all columns that are not listed after ORDER BY, is undefined, and can be different in repeated executions of the same SELECT statement.
There are also some [MANY > 1000] OSS notes on the subject (look for your database, e.g.  1858427 - Incorrect Sorting of SQL-Select Statement, 1859655 - The result set of an SQL-Select Statement may not be sorted, 1858479 - Result set of select statement is not sorted, 1858569 - Incorrect access to result set of SELECT statement, etc.)
Also if you sort an internal table and require records with same key values to keep their respective order, use the STABLE clause.
