What causes this issue?

The system has determined that there is already at least one actual line

fiscal year &V1&.

System Response

Since the balance carryforward sets <ZH>all</> totals values in period 0
of the new year to zero and then transfers the totals values of the old
year in period 0 of the new year, it is very likely that, after balance
carryforward, the totals of period 0 in the new fiscal year do <ZH>not
</> match the posted line items.

How to fix this error?

Check document &V3& and either reverse it or achive it before performing
balance carryforward.

• What is the cause and solution for SAP error message GU634 - If necessary, reverse document &3 for period 000 in &1; see long text ?

  The SAP error message GU634 typically indicates an issue related to the reversal of a document in a specific period. This error can occur in various modules, particularly in Financial Accounting (FI) or Controlling (CO), when there is an attempt to reverse a document that is not allowed due to certain conditions.
  Cause:
  
  Period Closure: The period you are trying to reverse the document for is closed. In SAP, once a financial period is closed, no further postings can be made to that period.
  Document Type Restrictions: Certain document types may have restrictions on reversals, especially if they are related to specific accounting processes.
  Configuration Settings: The system configuration may prevent reversals in certain scenarios, such as if the document is linked to a specific transaction type or if there are open items that need to be cleared first.
  Authorization Issues: The user may not have the necessary authorizations to perform the reversal in the specified period.
  
  Solution:
  
  Check Period Status: Verify if the period (in this case, period 000) is indeed closed. You can do this by checking the period status in the financial settings. If it is closed, you may need to open it temporarily to allow the reversal.
  Reversal in Open Period: If the period is closed, consider reversing the document in an open period. You may need to consult with your finance team to determine the best course of action.
  Review Document Type: Check the document type of the document you are trying to reverse. Ensure that it allows for reversals and that there are no restrictions in place.
  Consult Configuration: If you have access, review the configuration settings in the SAP system to see if there are any specific rules that prevent the reversal.
  User Authorizations: Ensure that the user attempting the reversal has the necessary authorizations to perform this action.
