Hi Sreeram,
You can create multiple assets simply by entering Number of similar assets "10" in AS01 T code. So 10 assets will be easily created.
In the PO line item, use the account assignment "A" for assets and in account assignment tab, choose distribution by percentage option and give the 10 asset number with 10% each.
Now make GR and it will be posted to 10 assets automatically.
Hope it solves.
Regards,
GSR
