Hello @JamesG 

Thank you for reaching out to the SAP Community and your questions

Here are the two clean patterns for SAP S/4HANA Public Cloud Edition (Fiori elements, OData V4):

List Report (table selection)

onCustomAction: function () {

  const extApi = this.base.getExtensionAPI();

  const ctxs = extApi.getSelectedContexts();           // v4 Context[]

  if (!ctxs.length) { sap.m.MessageBox.warning("Select a row first."); return; }

  const rowData = ctxs[0].getObject();                 // plain JS object

  // ...use rowData (or ctxs.map(c => c.getObject()) for multi-select)

}

Object Page

onCustomOPAction: function () {

  const ctx = this.base.getExtensionAPI().getBindingContext();

  if (!ctx) { return; }

  const obj = ctx.getObject();                         // header data

}

If you require rows from a specific sub-table on the Object Page:

const selected = this.base.getExtensionAPI().getSelectedContexts("MyStableTableID");

const firstRow = selected[0]?.getObject();

Hi Chuma,
Thanks for your response.This is my code:

sap.ui.define([
    "sap/m/MessageToast",
    "sap/m/MessageBox"
], function (MessageToast, MessageBox) {
    'use strict';

    return  {
        onAfterRendering: function () {
            this._ext =  this.base.getExtensionAPI();
        },
        Print: function (oEvent) {
            // const extApi = this.base.getExtensionAPI();
             const ctxs = this._ext.getSelectedContexts(); 
             if (!ctxs.length) { sap.m.MessageBox.warning("Select a row first."); return; }   
             const rowData = ctxs[0].getObject(); 
             console.log(rowData);
        }
    };
});

 I reached this point by running the code: const ctxs = this._ext.getSelectedContexts(); At that time, an error occurred: "Cannot read properties of undefined (reading 'getSelectedContexts')".
How should I handle this situation?
Best Regards
