本方案实现在凭证分录中，所有挂了指定维度的科目，当该维度未录入时，批量填充指定的维度值，或批量清除指定的维度。

        方案思路：扩展凭证，增加【维度选择】下拉列表，【维度值】文本框和【批量填充】【批量清除】按键。当点击按键【批量填充】时，自动遍历当前凭证的所有分录行，如当前行科目如果挂了指定的维度且未录入内容时，就自动将维度值填充进去。【批量清除】则实现自动将指定的维度值清空。

• 扩展凭证，增加【维度选择】下拉列表，【维度值】文本框和【批量填充】【批量清除】按键

  在BOS设计器中，实现上述内容，注意各字段的标识值分别为：FFlexCombo，FFlexValue和FBtFill，FBtClear。注意标记部分的属性内容如下：

  
  

• 完成后的界面如下图所示：
  

• 注册凭证表单插件

  找到组件的dll文件，在BOS设计器的凭证表单插件中完成插件注册：
