ABAP ALV控件单元格编辑设置DEMO

原来一直没用到这么深，这2天开始关注这块，基本上搞清楚了。

1、使用的ABAP ALV 控件是： REUSE_ALV_GRID_DISPLAY_LVC 。

 

2、DEMO程序运行后的效果，等于4700000005的PO，PO ITEM列的单元格时可以编辑的：

3、注意内存数据结构，这个清楚了，就很好理解是怎么玩的。在数据表的每一行末，还有一个小表，这个表存放这一行中哪些字段可编辑，哪些不可编辑的信息（所以需要表数据）。程序工作起来，需要控制每一行末的这张EDIT小表，给它相应的数据，才能控制单元格的编辑状态。

4、对于REUSE_ALV_GRID_DISPLAY_LVC函数，我目前只能打开一整列为可编辑状态，然后关闭不编辑的单元格。

全部DEMO的程序，如果你没有PO数据，换一个有数据的client试：
