掌上报销单据体附件二开方案

【应用场景】

费用报销PC端相关单据，单据体可通过配置菜单点击事件关联（单据体附件管理）的操作可以实现单据体附件功能，移动端需要二开实现

【注意事项】

该实现方案目前只支持掌上报销5类单据的费用明细，差旅费报销单2019新政行程明细的单据体暂不支持

【案例演示】

PC端费用报销与掌上报销单据头与单据体的映射关系：https://vip.kingdee.com/article/439370655386174720?productLineId=1&isKnowledge=2

【实现步骤】

<1>根据上面的映射关系找到对应的移动表单，以费用报销单为例：

费用报销单分录编辑（单据体）=》ER_MBReimb_ExpItemV3(掌上报销V3_申请/报销单分录)

在BOS设计器中找到ER_MBReimb_ExpItemV3(掌上报销V3_申请/报销单分录)这个表单，然后添加附件布局。

由于是共用表单，附件布局的高度设置为0，由具体的业务插件去设置重新高度。
