IDOC Status

Hi,

I am generating the IDOC using function module IDOC_INBOUND_SINGLE in my program I want to check the status of the generated IDOC in my program after the above function module so can you please tell me what logic I can apply in this location. Please help me and one more doubt is I am in selection screen and if I press back button I need to go to sap easy access screen. For this already I created pf status and I am using following logic but after pressing back button twice it is going to sap easy access. But I want after pressing back button only once.

Case sy-ucomm.

When ‘ BACK’.

Leave to screen 0.

Please help me.

Thanks a lot.
