• What is the cause and solution for SAP error message TU864 - The new cumulated amount cannot be lower than the proposal ?

  The SAP error message TU864, which states "The new cumulated amount cannot be lower than the proposal," typically occurs in the context of financial transactions, particularly when dealing with budget management, purchase orders, or similar financial documents. This error indicates that the system is preventing a transaction because the new cumulative amount being entered is less than the proposed amount, which is not allowed according to the business rules set in the system.

  Review the Proposal Amount: Check the proposal amount that is currently set in the system. Ensure that the new cumulative amount you are trying to enter is greater than or equal to this proposal amount.
  Adjust the New Amount: If the new cumulative amount is indeed lower than the proposal, adjust it to meet or exceed the proposal amount.
  Check for Budget Availability: If applicable, verify that there is sufficient budget available to accommodate the new cumulative amount.
  Consult with Finance Team: If you are unsure about the amounts or the implications of changing them, consult with your finance or accounting team to ensure compliance with internal policies.
