Line item settlement is not possible for asset error

Hello All,

We have created an asset class in which we have selected investment measure as status of AUC, further we have updated inv. measure asset class investment profile in which we have selected line item settlement and list of origins.

Client requirement is to automatically create asset while creating WBS, asset created automatically under AUC.

We were able to settle the cost from WBS to AUC, I'm able to view the settled balance in AUC.

Now if I try settle the balance from AUC to final asset its providing following error.

"Line item settlement is not possible for asset"

Can you please guide me to transfer the balance to final asset.

Regards

Magesh
