• What is the cause and solution for SAP error message FK123 - A date was already entered for this year ?

  The SAP error message FK123 ("A date was already entered for this year") typically occurs in the context of financial transactions, particularly when dealing with document postings in the Financial Accounting (FI) module. This error indicates that a date has already been used for a financial document in the current fiscal year, and the system is preventing the entry of another document with the same date.
  Cause:
  
  Duplicate Date Entry: The most common cause is that a financial document (like an invoice or payment) has already been posted for the same date in the current fiscal year.
  Document Type Restrictions: Certain document types may have restrictions that prevent multiple postings on the same date.
  Posting Period Control: The system may be configured to restrict postings to a single date within a specific period.
  
  Solution:
  
  
  Check Existing Documents: Review the existing financial documents posted for the current fiscal year to see if a document has already been entered for the date in question. You can do this by using transaction codes like FB03 (Display Document) or FBL1N (Vendor Line Item Display).
  
  
  Change the Posting Date: If you find that a document already exists for that date, consider changing the posting date of your new document to a different date that does not conflict with existing entries.
  
  
  Review Document Type Settings: If you believe that multiple postings on the same date should be allowed, check the configuration of the document types in the SAP system. This can be done through transaction code OBY6 (Document Types) to see if there are any restrictions.
  
  
  Consult with Your SAP Administrator: If you are unsure about the configuration or need to change settings, consult with your SAP FI administrator or a consultant who can help you adjust the settings appropriately.
  
  
  Check Posting Periods: Ensure that the posting period is open for the date you are trying to use. You can check this in transaction code OB52 (Open and Close Posting Periods).
  
  
  Related Information:
