For using select options we use a webdynpro component called WDR_SELECT_OPTIONS which has all the select options properties predefined inside it.

In the View create a View Conatiner UI element to hold the select options component.

Now for search help change the code for I_VALUE_HELP_TYPE ,CO_PREFIX_NONE to CO_PREFIX_OVS. Normally when we create node attribute we can provide search help in the properties. But for Select options we don’t have any predefined node so we can use OVS help here.

Now create a handler attribute for Select options and also create a handler method for the OVS

Now to transfer select options value from one view to other, create a view attribute which refer to IF_WD_SELECT_OPTIONS. This variable will hold the select options value .We are going to export this in our outbound plug and use it in the next view to read the select option.

Here LV_VAR is a second variable for a field which we will create in the view later for a field VBTYP.

Now create a outbound plug and and export the two variable which we are going to use in next view.

Now assign the helper reference to the handler variable.
