SRM close buttom when login from favorites

HI All,

We have problem in SRM shopping cart where close button is not displayed when we copy the URL into favorites and use it.

In debugging If we make the below variable as "X" then Close Button appears

CHECK_IF_CLOSE_AVAILABLE (CL_FPM_FLOORPLAN_ASSIST)

* Check WD application settings

lo_application_api = io_component_api->get_application( ).

rv_close_supported = lo_application_api->get_is_close_window_supported( ).

IF rv_close_supported = abap_false.

1. RETURN.
2. ENDIF.

If any one knows the issues kindly suggest me where I need to make the changes, as I am new to SRM.
