Hi prasanna
1) In the  dc1 (popup dc)
Component controller
Create a pop up calling method
//@@begin javadoc:Callpopup()
/** Declared method. */
//@@end
public void Callpopup(  )
//@@begin Callpopup()
//popup steps
//@@end
2) component interface controller
Add the usage of component controller of model dc component
create a method in interface controller for calling the method Callpopup in component controller
//@@begin javadoc:Interfa_ctl_mthd()
/** Declared method. */
//@@end
public void Interfa_ctl_mthd( )
//@@begin Interfa_ctl_mthd()
wdThis.wdGet<modeldc>Controller().Callpopup();
//@@end
3) Open the DC Metadata>Public Part>New public part
Give a name and Select the API and in the Select Entity type, select the web dynpro component and in the select entity which is at the bottom of select entity select the dc1/component (Ie component inside the web dynpro component)
4) Build and deploy the  dc1
DC2
1) Expand the DC metedata > used DC >right click and select add used dc and select the  dc1 and select the build type in dependency tab
2) Expand the web dynpro component structure and Select the Used web dynpro component and right click and select used webdynpro component and browse the component and give a name ie popupcomp
3)In the view of project dc define the usage of the component popupcomp
In any action of button , call the popupcomp comp like this
//@@begin javadoc:onActionGo(ServerEvent)
/** Declared validating event handler. */
//@@end
public void onActionGo(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
//@@begin onActionGo(ServerEvent)
wdThis.wdGetpopupcompInterface().Interfa_ctl_mthd();
//@@end
for popup code look at this thread
