Hi kishore ,
There are couple of things you need to check for this.
1) date of capitalisation on asset ,
2) Can you please untick detail log check box and just run as test run without any error log.When you run AFAb with error log this only gives yoy asset unless its in error .
So please run in text more WITHOUT ANY Error log .
I am sure you will find your asset there and the you can run in update mode in background .
