Session should logoff on click of save button in webgui window

Hi All

I am directly changing section 80 details using WEBGUI ervices( PA30 tcode with infotype 585 in change mode) WITH BELOW URL

'http://XXXXXXXXXXXXXXX/sap/bc/gui/sap/its/webgui?~transaction=*pa30%20RP50G-PERNR=' lv_aempid

';RP50G-choic=0006;RP50G-SUBTY=4;RP50G-begda=01.01.1800;RP50G-endda=31.12.9999;DYNP_OKCODE=CHG'

So user able to change their details using above URL, but when user clicks on save button, it is showing PA30 main screen..I want o know how to avoid this screen...

My requirement is when user clicks on Save button, it should save and logoff from session.*
