2510553 - Backend Error Message Occurs When Trying to Reverse Payment Allocation


You want to reverse a Payment Allocation and click the Reverse button. Instead of reversing the Payment Allocation the system raises a backend error message.

Reproducing the Issue

  1. Go to Payment Management work center.
  2. Go to Payment Allocation subview.
  3. Show all Payment Allocations in status posted.
  4. Select Payment Allocation ID XXX ( XXX represents the Payment Allocation ID).
  5. Click Reverse button.
  6. An error mesage is raised


When you posted the respective Payment Allocation you used G/L Account XYZ with G/L Account Type ABC. (XYZ represents the G/L Account number ABC represents the G/L Account Type description).

In the meantime you changed the G/L Account Type from ABC to DEF. Since you used the same G/L Account with a different G/L Account Type for the posted Payment Allocation it is not possible to reverse the Allocation.

An error occurs as a result of a different G/L Account Type for G/L Account XYZ in Payment Allocation and Business Configuration.



To be able to reverse the Payment Allocation you have to maintain the same G/L Account Type for the G/L Account you used when you posted the Payment Allocation.

  1. Go to Business Configuration work center.
  2. Go to Overview subview.
  3. Show All Configuration Elements and find Activity Charts of Accounts, Financial Reporting Structures, Account Determination.
  4. Select Edit Chart of Accounts.
  5. Choose the respective G/L Account and maintain G/L Account Type.
  6. Save your changes.

You should be able to reverse the Payment Allocation now without a backend error message.
