Editing the PO Variance Account on the Purchase Order

Summary

Can we manually edit the variance account while creating the purchase order

Content

I would like to if there is a way to manually edit the variance account on the PO after the account is defaulted from the rules written in the  Transaction Account Builder.

The account gets defaulted but it does not allow us the edit it.  Just want to check if there is an option to allow the manual edit.

 

Thanks in Advance,
