1、首先要构建BOTRelationInfo对象，关键要通过BOTRelationInfo的方法getRelationEntries()获取分录集合BOTRelationEntryCollection；

     如：BOTRelationInfo relaInfo = new BOTRelationInfo();

         BOTRelationEntryCollection relaEryCol=relaInfo.getRelationEntries();

2、再根据BOTRelationEntryCollection分录集合的方法add方法，把构建好的分录对象BOTRelationEntryInfo添加进去；

     如：BOTRelationEntryInfo relaEtyInfo = new BOTRelationEntryInfo();

            relaEtyInfo.setRelation(relaInfo)

           relaEryCol.add(relaEtyInfo);

3、最后通过BOTRelationFactory.getLocalInstance(ctx).addnew(BOTRelationInfo)，实现整体保存。

     如： BOTRelationFactory.getLocalInstance(ctx).addnew(relaInfo);

整体代码结构如下：

    BOTRelationInfo relaInfo = new BOTRelationInfo();

    BOTRelationEntryCollection relaEryCol=relaInfo.getRelationEntries();

    BOTRelationEntryInfo relaEtyInfo = new BOTRelationEntryInfo();

    relaEtyInfo.setRelation(relaInfo)

    relaEryCol.add(relaEtyInfo);

    BOTRelationFactory.getLocalInstance(ctx).addnew(relaInfo);
