    Hi Nitin Verma  I followed exact same steps. I added the code on page extension for sales line and I blocked a item in the item card and tried to add the  same blocked item to the sales line still no any error messages .

    Hi, I don't think this needs to be customized, the standard system has some controls about the Blocked item.

    More details: How to block items (Block, Sales Blocked, and Purchasing Blocked)

    Hope this helps.

    Thanks.

    Then please move your code into Page extension

    pageextension 50104 MyExtension extends "Sales Order Subform"

    {

       layout

       {

           modify(Quantity)

           {

               trigger OnAfterValidate()

               var

                   ItemS: Record Item;

                   TEXT2: Label 'This item is blocked %1 ';

               begin

                   IF rec.Type = Enum::"Sales Line Type"::Item then

                       if ItemS.Get(rec."No.") then

                           if ItemS.Blocked then

                               Error(TEXT2, ItemS."No.");

               end;

           }

           // Add changes to page layout here
