How to correct the asset cost difference

Hi Team ,

Asset cost difference not corrected

Context : There is an invoice which is matched with a po and the po account was Expense and the account on the Asset also Expense ...

however there is an difference on the asset cost  for an asset. Usually, FA corrects the difference coming from AP automatically. 

did the amount automatically get corrected ?

How to correct the asset’s amount ? 

Can you please explain the process to follow ?

And do you have any idea about the reason why this amount wasn’t automatically corrected  ?

Please let us know .

Thanks
