MDG Enrichment Spot Issue - Webdynpro not opening.

We are working on MDG 8.0, and need to implement enrichment functionality for Material with custom screen containing additional data coming from web service, on clicking OK, it should get populated on entity level. We created a new feeder class, adapter class custom webdynpro component and configured it on 'Define enrichment spot' in MDGIMG.

Feeder class / adapter class and web dynpro components inherit specific required interfaces and code is written in all redefined methods as per SAP standard document as per below link.

https://www.sap.com/documents/2015/07/8cad25ba-557c-0010-82c7-eda71af511fa.html

'Execute' method of adapter class contains select query to populate data in at UI level. *but there is no UI call (through code) written in it.

Webdynpro component configured above is created and implements interface 'MDG_ENRICHMENT_INTF' and code is written in show_enrichment_ui method to open popup window. View is created to show small table having material and description details.

we have enabled Enrichment at Material CR -> Step level(*in step properties), so that on pressing CHECK button, it should work.

In debugger we have checked that execute_enrichment method is getting executed without any issues also . Control is reaching feeder and adapter class.

Everything stated in above document is implemented , but Web dynpro component is not getting triggered. I tried putting breakpoint in show_enrichment_ui method of webdynpro, but that is also not getting triggered.

Is there anything I am missing. As per the document we have done everything. But not sure why webdynpro is not getting popped up.

We checked below two document already.

Please let is know if this can be done or not .
