How to initialize standard component SRQM_INCIDENT_H which is navigated from custom ZCOMPONENT

Hi expert .

     I have a scenario to create ZCOMPONENT UI that contain 1 MainWindow with 1 outbound plug. Then I take  SRQM_INCIDENT_H (standard UI component ) as a usage component of my custom ZCOMPONENT and create a navigation link from ZCOMPONENT/MainWindow to SRQM_INCIDENT_H/MainWindow with enhancement inbound plug. The problem is when the screen of standard component ( service request )  displayed. All fields  shown the text "XXXXXXXXXnot bound".

   It is  difference from direct click on menu in home screen. All fields in service request screen  shown as input field.

ZCOMPONENT---------------------------------->SRQM_INCIDENT_H  (this  show field not bound)

Link on home screen--------------------------->SRQM_INCIDENT_H (everything work fine)

I have been noticed that IP_CREATE (standard inbound plug of SRQM_INCIDENT_H) was fired. When someone direct click link on menu in home screen.  And I try to do the same by make a call  IP_CREATE method  inside my enhance inbound plug. But it doesn't help.

if someone know the solution , Please let me know.

Thanks in advance.

PS. Sorry  my english is not well.
