1. Navigate to System Definition > Scripts - Background.
2. Paste this test script:

   // Test script to query SAP Purchase Orders
    var gr =
           new GlideRecord('sn_erp_cp_procurement_purchase_order');
    gr.setLimit(5);
    gr.query();
   
    var errorMsg = gr.getLastErrorMessage();
    if (errorMsg) {
       gs.error('Query failed: ' + errorMsg);
    }
           else {
       gs.info('Query successful!');
       var count = 0;
       while (gr.next()) {
           count++;
           gs.info('PO: ' +
           gr.getValue('po_number') + 
                   ' - ' + gr.getValue('vendor_name'));
       }
       gs.info('Total: ' + count);
   
         }

3. Click Run script.
4. Check output - you should see PO data from SAP.

Now search for a specific PO (replace with your actual PO number):

// Search for specific PO
 var poNumber =
        '4500123456'; // Replace with your PO

 var gr = new GlideRecord('sn_erp_cp_procurement_purchase_order');

        gr.addQuery('po_number', poNumber);
 gr.query();

 var errorMsg = gr.getLastErrorMessage();
 if (errorMsg) {
    gs.error('Query failed: ' + errorMsg);
 }
        else if (gr.next()) {
    gs.info('Found PO: ' + gr.getValue('po_number'));
    gs.info('Vendor: ' + gr.getValue('vendor_name'));
    gs.info('Amount: $' + gr.getValue('total_amount'));
    gs.info('Status: ' +
        gr.getValue('status'));
 } else {
    gs.warn('PO not found: ' + poNumber);

        }
