• What is the cause and solution for SAP error message 5C634 - Value date &1 comes before lock date &2 of account '&3' ?

  The SAP error message 5C634 indicates that there is a conflict between the value date of a transaction and the lock date of the account. Specifically, the value date (the date on which the transaction is considered effective) is earlier than the lock date (the date after which no changes can be made to the account). This typically occurs in financial transactions where certain periods are locked to prevent changes, such as during month-end or year-end closing processes.
  
  Cause:
  
  Lock Date Set: The account has a lock date set, which prevents any transactions with a value date earlier than this lock date.
  Transaction Date: The transaction you are trying to post has a value date that is before the lock date of the account.
  Period Closing: The error often arises during financial period closing when certain accounts are locked to ensure data integrity.
  
  
  Solution:
  
  Check Lock Date: Review the lock date for the account in question.
