I am entering vekp-exidv2 value on the selection screen and if I press execute button then it is displaying some values and some values I am entering manually on the second screen. These two screen I have designed using screen painter. On the second screen if I press save button I am generating idoc inside of that idoc hu is generating. After that If I select back button it is going to selection screen again and I am changing vekp-exidv2 value and I am again doing the same process but it is giving error. If I come out from the total thing and if I start again with same thing it is working fine. I used refresh commands properly.But still it is giving the same error. I am using the function module idoc_inbound_single to generate the idoc in my program. Please help me where I did the mistake. Please help me I will give the points.
Thanks a lot.
