      Hi Vignesh ,

      Firstly thanks for sharing such type of document which is very useful to us.

      I am facing a issue when we are assinging lv_string to gv_hit_count.It is giving error field symbol not yet asigned.

      ASSIGN lv_string TO <gv_hit_count>


      Can you please help me for this issue.


      Again , i am appreciating you to sharing such kind of document.

      Regards,

      I unable to understand this line:

      Create a instance attribute "GV_HITCOUNT" and fill in the on_new_focus of the resulting context node in the which Title has to be updated with the Counts.

      What is the type gv_hitcount attribute ?

      Can you explain in detail it would be helpful,

      Hi Vignesh,

      Thank you for sharing the document.

      I'm trying to accomplish a similar requirement for the assignment blocks on the homepage WCC_SRV_HOME and even though I'm able to set the values in view_area table, the new assignment block title is not displayed, instead the default title is fetched and displayed.

      Also, since  lr_view is always bound, the update_view method is never triggered ( is it the correct behaviour? )

      Thanks!
