有時我們的ALV列數難以確定，如果采用列數上限固定的話，可能會很多（此時不能正確全部），或者很少（此時平白無故運行時多占用內存），所以比較好的方法是，使用Method? cl_alv_table_create=>create_dynamic_table動態創建顯示用的內表，這樣的話，就不會受到列數限制了(ALV本身支持列數上限的情況除外)。
先看效果：


如果選中下方ALV的藍色部分字段，按下屏幕上的Change按鈕后(假設選中了Document Type列)：

發現上圖中，行和列已經產生了變化。如果選擇Company Code和Fiscal Year的話，也是可以互換行列的。
=>也許有人覺得這個功能沒啥用，但實際現在很火的BI，就是提供了各種維度(Dimension)的數據統計，使傳統的report受到了巨大的沖擊。當然，我這里做的這樣的一個小功能，還是和BI的強大功能相去甚遠的，但是如果正好有類似的需求，又沒有上BI，那倒也不失為一種退而求其次的方法

具體實現代碼如下：
