Single selection in the list report view table is enabled by default. If desired, you can enable multi-select single-action for your app.
This allows users to select multiple items from the table in the list report and then choose a simple custom action button. After triggering the action, the user stays on the same page (no navigation) on which error messages will also be displayed.
"sap.ui.generic.app": { "_version": "1.1.0", "pages": [ { "entitySet": "STTA_C_MP_Product", "component": { "name": "sap.suite.ui.generic.template.ListReport", "list": true, "settings" : { "gridTable" : false, "multiSelect" : true }
Note that the custom action button must not have action parameters, and the results must be displayed on the page on which the action has been triggered.
