Button missing (add Action) in Acumatica 2020 R1

Hi @SadokHanini ,

Please use the below example to add a new action in “Actions” menu.

Example from SOOrderEntry Graph Extension.

 public class SOOrderEntryExt : PXGraphExtension<SOOrderEntry>
    {
        public override void Initialize()
        {
            base.Initialize();
            Base.action.AddMenuAction(validateAddress);
        }



   public PXAction<SOOrder> validateAddress;
        [PXButton]
        [PXUIField(DisplayName = "Validate  Address", MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select, Enabled = true)]
        protected virtual void ValidateAddress()
        {
                         // Button logic here
​​​​​​​ 
        }
    }
