EGO_ITEM_PUB not working

HI Guys,

When I am running following code from Oracle Applications, its not working but within PL/SQL, it works fine:

--select * from fnd_user where upper(user_name) like '%ALI%S%';

DECLARE

   l_item_tbl_typ                               ego_item_pub.item_tbl_type;

   x_item_tbl_typ                               ego_item_pub.item_tbl_type;

   x_return_status                              VARCHAR2 (100);

   x_msg_count                                  NUMBER;

   x_message_list                               error_handler.error_tbl_type;

BEGIN

   fnd_global.apps_initialize (20081--21752

                            , 51886

                             , 401

                             );

   l_item_tbl_typ (1).transaction_type := ego_item_pub.g_ttype_update;

   l_item_tbl_typ (1).inventory_item_id := 960614;

   l_item_tbl_typ (1).organization_id := 172;
