Y9020010: Construction of an internal table with “APPEND itab”

In this simple report example a small data base is created for an internal table. After the declaration of the internal table T1, the construction of the table data is undertaken in a subroutine. In a DO-loop, the table header line of T1 is filled with continuously modified values. After that, the header line is added to the data base with “APPEND T1”.
