在SAP的HCM開發中經常會用到ALV，剛開始的時候只知道用 REUSE_ALV_GRID_DISPLAY_LVC這個Function就可以把數據顯示出來（這里只說grid），但是這個Function里面的參數屬性卻一直糊里糊塗的，所以到后來報表開發越來越復雜的時候，就發現懂得Function里面參數的用法非常關鍵，比如說ALV的分類小計要用到IT_SORT這個參數，列寬等ALV布局要用到IS_LAYOUT參數等等。你要是不知道這些參數的存在或者是不知道它們的用法的話你根本就沒辦法做。基於自己的這種艱苦的摸爬滾打歲月，就把我知道的ALV參數屬性作下總結。

ALV_S_FCAT說明：字段類別 (用於 LVC 和 KKBLO)
INCLUDE <cl_alv_control>的說明：里面有好多ALV布局的屬性，中文意思跟英文單詞意思同樣理解
***INCLUDE <CL_ALV_CONTROL> .

附上一個網上找到的例子（可直接運行），改例子是關於設置ALV單元格內字體格式的，比如說粗體，其它ALV控制的操作可以看我博客SAP-ALV分類的其它文章。
