## Answer This is because the child table items are displayed on the "[List Screen](/en/manual/table-grid)". --- ## Overview When a parent-child table is linked using the table link function, if the child table items are displayed in the parent table, the checkboxes in the left column are not displayed, so "[Bulk Update](/en/manual/table-record-bulkupdate)" and "[Bulk Delete](/en/manual/table-record-bulkdelete)" cannot be performed. This is to prevent erroneous operations such as accidentally deleting records. Normally, checkboxes are displayed in the left column of the list display.  If the child table items are enabled in the parent table list as shown below, the checkboxes are not displayed in the list display.  This is to prevent erroneous operations, as multiple rows of parent table records are displayed.  ## Related Information <div id="ManualList"><ul><li><a href="/en/manual/table-grid">Table Function: Record Screen Index</a><span>10.02.2024 up</span></li> <li><a href="/en/manual/table-record-bulkupdate">Table Function: Record Bulk Update</a><span>08.13.2024 up</span></li> <li><a href="/en/manual/table-record-bulkdelete">Table Function: Bulk Delete Records</a><span>08.13.2024 up</span></li></ul></article></div><input id="SearchTextHidden" type="hidden" value="" />
