X++取消一个Purchase Order的方法

高手总结了2个办法，我只采用method1

1. 就是继承PurchCancel类，然后调用run方法。 因为PurchCancel的construct和parmPurchTable都是protected方法

详情参考下面URL

Method 1:

1) Make a class and extends from PurchCancel class

2) PurchCancel purchCancel;

   purchCancel = PurchCancel::construct();

   purchCancel.parmPurchTable(_purchTable);

   purchCancel.run();
