Reproducing the Issue

  1. Go to the Payment Management work center, and select the Payment Allocations view.
  2. Show all In Preparation allocations, and select the one in question.
  3. Edit the Payment Allocation, and you could see that the open amount is zero.
  4. Choose the Post button.
  5. You can see error message: 'Net Amount missing'


The error reported is that you tried to post the payment allocation in both the Customer/Supplier tab and Allocation to G/L account tab. You have filled incorrect details, in either Customer/Supplier tab or Allocation to G/L account tab.

For Example:

Over the payment allocation screen you have maintained the correct details in the Customer/Supplier tab.
You went to the 3rd tab - Allocation to G/L Account. You have entered only the G/L Account and missed to enter the credit/debit amount. When you click on post at that time system throws the error message.


Make sure that the details are filled correctly while allocating payment. If you are trying to allocate the amount in - Supplier/Customer tab and Allocation to G/L account tab then, the details should be filled correctly.
