On your table in the AOT, overwrite the modifiedfield method. For an example on how to overwrite, check the purchline.modifiedField method for example. Just add a case in the switch:
在AOT中的表上，覆盖modifiedfield方法。有关如何覆盖的示例，请检查purchline.modifiedField方法。只需在交换机中添加一个案例：
case fieldnum(YourTable, ItemId) this.itemName = inventtable::find(this.itemid).name(); break;
case fieldnum（YourTable，ItemId）this.itemName = inventtable :: find（this.itemid）.name（）;打破;
Unless really necessary, adding both the itemId and itemName is not needed, as you are de-normalizing the database at the point. It is probably better to add a display method for the itemname to your grid.
除非确实有必要，否则不需要同时添加itemId和itemName，因为您在此时要对数据库进行反规范化。最好将itemname的显示方法添加到网格中。
