1、 scene tbl_work_order Work order form ,tbl_work_order_show Work order data display table The historical data is added to the work order data display table

2、 The original work order display table of historical data has no equipment type data , Due to the addition of equipment types , If there is no work order type of historical data, you need to add the equipment type data

3、 Set the type equal to 4 Add equipment type data to the display table of vehicle terminal maintenance ,

The effect is as shown in the picture ：
