请帮忙解决：ORCAD原理图BGA多部分组成产生问题

由于BGA U11引脚多分成了14部分，在放置过程中有修改引脚，在DRC时产生了如下问题，

请帮忙解决，谢谢！

对于这种多引脚的东西,最好把库建好了再画线路图,在绘图过程中最好不要修改库,

建库后，在画原理图时发现零件脚序号有误，在原理图中更新了当前部分，结果重复操作多次后，发现BGA U11有10多个PACKET应用到原理图中了，此时再改零件编号到一致，结果出现了上述错误，无法产生NETLIST给其他LAYOUT软件用。现想重新建零件，将当前应用在原理图零件部分COPY下来，但PASTE时没有了脚的编号，如果重新定脚的编号又有大量工作要做，请问是否有解决方法?望ORCAD高手指点
