Manual payment is allowing to enter the payment for the previous date

Dear community,

For a manual type of payment the application is allowing me to enter the payment for a previous date. It should not allow pre-dated transaction as long it is not enabled at the Payable options for the respective operating unit.

Steps:

1. Create Invoice

2. Create the payment manually from the payment workbench.

3. Trying to change makes the pre dated transactions.

Please advise!

thank you in advance,

Alex
