Content (required)

Once we create a lease and activated in lease accounting module with payment amounting to 10,000 USD belonging to Business unit 101, which got accounted in the first month.

Now in the 2nd month, in the same payment created in lease, we want to update both the payment amount information to 15000 USD and the accounting information with different business unit as 102. we tried this with Amend lease and it is not allowing us to update the payment amount details.

Could you please let us know how can we do that.
