How to create POPUP alv in the same view without any OnAction Event?

Hi,

I have a requirement to display Popup ALV in the Component Controller WDINIT method. Requirement is as follows:

1. Employee login to ESS, based on certain conditions first I have to fetch Employee Number using FM RP_GET_PERNR_FROM_USERID

    from Employee Login(UserName)

2. I have to fetch data from PA20001 for employee number(PERNR)

SELECT PERNR

        SUBTY

        ENDDA

        BEGDA FROM pa2001

INTO CORRESPONDING FIELDS OF TABLE lt_pa2001

WHERE pernr = lv_pernr AND subty = 'ITEL'.

3. I have to display POPUP alv for this selected data.

Here I am able to display ALV but not POPUP alv as it requires OnAction event to call GET POPUP message and for that we need to click on some button to trigger that action. However in my requirement this POPUP ALV should come without any OnAction Event.

Kindly help me in this.
