Thanks all.
I know about SPAU/SPDD activity.I have read somewhere EHP7 is not supporting BSP application.Portal version goes to 7.1 to 7.4 so our custom workflow is working or we should do any changes on UWL level.We have around 10-12 interfaces related to PI.It should be work or not.I think somewho webdynpro syntex changes in EHP7 compare to EHP3.
