Leseprobe
2.1 Create the ABAP program
A preview of the ALV output from this initial program is shown in Figure 2.1.
Figure 2.1: Preview (function module – FM)
Using transaction code se38 (or se80, if you prefer), type a name for the new program, then click on the create button. (I have used the name ZKK_ALV_FM for this initial program.) Complete the Type and Status fields (Figure 2.2), then click on the save button. When prompted for the Package, click on the Local Object button. This fills the Package field with $TMP and positions your cursor in the new program.
