We can reuse existing search helps from the ABAP dictionary.However ,there are not available search helps for all data types in the system.One way of creating Input Help is to include OVS (Object Value Selection ) value help,is implemented by system side effort.After enetering OVS value help for context attribute ,while the run time,The OVS component is then automatically triggered when a user presses the F4 button for a selected input field ,simultaneously ,Dialog box also created automatically on the...

How to Create Messages in WebDynpro ABAP To trigger error ,warning and display messages in WebDynpro ABAP component ,is another important mandate for webdynpro consultants.In the previous lessons ,we have learnt reading attributes , structures and writing data to context elements  .The next step is learning triggering messages in components .This is very important lesson because , we must be learn the displaying message coding part to complete a dynpro component.For that i am sharing my knowledge here with you to develop message part. For this ,first of all , we have to integrate messages message log using the message manager.Next message manager is integrated into webdynpro code wizard. First of all, we have to get message manger . DATA:L_current_controller type ref to IF_WD_CONTROLLER, L_message_manager type ref to IF_WD_MESSAGE_MANAGER. L_CURRENT_CONTROLLER?=WD_THIS->WD_GET_API().

How to Write Data to Context Elements in ABAP WebDynpro In the previous lessons ,we have learnt reading attribute and structure values from context element .Now we will learn how to write data to context element in ABAP WebDynpro .Reading and Writing data to context elements is very important part for every webdynpro developer because if you know these two techniques ,you can simply build any webdynpro application .Here i am sharing two different methods that writing data to existing context elements and new context elements and how to generate new context element there after setting the values for generated element. Writing data to Existing Context elements Method ABAP_TUTOR9. DATA:I_node type ref to IF_WD_CONTEXT_NODE,            I_my_struc type ref to IF_MY_CONTROLLER=>element_node_1. I_node = wd_context->get_child_node(wd_this->wdctx_node_1). I_node->s et_static_attributes(static_attributes= I_my_struc ). Endmethod. ...

How to Read Structure from Context Element in ABAP Webdynpro In the previous ,we have learnt reading attribute value of context element ,in this lesson,we will learn how to read structure from context element .It is most important as a ABAP WebDynpro developer ,second step is to learn reading structure static attributes ,reading the structure of any element and reading specific element of node .So now let us start learning method structures to access values. In the first step,we will learn reading static attributes of structure. Method ABAP_TUTOR. DATA:I_node type ref to IF_WD_CONTEXT_NODE,      I_my_struc type ref to IF_MY_CONTROLLER=>element_node_1. I_node = wd_context->get_child_node(wd_this->wdctx_node_1). I_node->get_static_atributes(importing static_attributes= i_my_struc). Endmethod.

Reading  Attribute Value of a Context Element in ABAP WebDynpro  In this post,we will learn how to read attribute value of context element in WebDynpro ABAP.It is important that after learning reference variables in webdynpro ,the next important step to learn what is node and element and attribute which are basic elements in webdynpro .So now let us know the get access the element of 'wd' component . Every webdynpro component contains the root node and child nodes .Child nodes contains the Attributes and attributes are elements of node and every element contains set of values that are string values .So in webdynpro we have to access the final value of node.For this ,we have to create reference variables for nodes ,elements and storing values. The easiest way to read attribute value of 'lead selection of the element of a node. Method abaptutor. Data:I_node type refer to IF_WD_CONTEXT_NODE,          I_element type refer to IF_WD_CONTEXT_ELE...

Reference Variables  in ABAP WebDynpro Reference variables or attributes or object references or instances ,all are same SAP ABAP WebDynpro .These are used as object references for current controller and interfaces and also used to access the root   node  .So here there are two different instances are available which are 'wd_this' and 'wd_context' and we learn the use of these two reference variables. WD_THIS is a reference variable or 'instance' for the current controller :IF_VIEW_NAME. WD_CONTEXT is a reference variable or instance for   'root context node':IF_WD_CONTEXT_NODE. Normally ,in webdynpro component,whenever a view has been created , view interface will be created by system (IF_VIEW_NAME) and object reference for this interface is 'WD_THIS'. Some interfaces related to  Node->IF_WD_CONTEXT_NODE. Parent Element->IF_WD_CONTEXT_ELEMENT. We are using WD_CONTEXT reference variable or object refer...
