Static/Context based Value Help

Instead of standard value help we can add custom value help; this can be form context of Adobe form. In this case there is need of coding. For this valuehelp you need to have a context node with two fields one for value and another for corresponding text. As we are proceeding with WebDynpro ABAP, weneed to fill this node WDINIT method of WebDynpro view or controller.

Step1: Create a context node with Value and Text. Text is optional here.

Step2: Select corresponding Values and texts into one internal table or populate internal table with possible values and bind that internal table to contextnode.

Sample Coding:

* Create internal table

types: begin of x_country ,land1 type t005-land1,

end of x_country.data: t_country type STANDARD TABLE OF x_country.

* Select Dataselect land1

from t005into table t_country.

DATA lo_nd_adobedata TYPE REF TO if_wd_context_node.DATA lo_nd_countrynode TYPE REF TO if_wd_context_node.DATA lo_el_countrynode TYPE REF TO if_wd_context_element.DATA ls_countrynode TYPE wd_this->element_countrynode.
