• What is the cause and solution for SAP error message WY095 - Specify a valid period ?

  SAP Error Message:
  
  WY095 - Specify a valid period
  
  Cause:
  The error message WY095 - Specify a valid period typically occurs in SAP when a user enters an invalid or incorrect period in a transaction that requires a valid fiscal or posting period. This can happen in modules like FI (Financial Accounting), CO (Controlling), or MM (Materials Management) when posting documents, running reports, or performing period-dependent activities.
  Common causes include:  
  
  The period entered does not exist in the fiscal year variant assigned to the company code.  
  The period is outside the open posting periods (e.g., trying to post in a closed period).  
  The period format is incorrect or not recognized by the system.  
  The fiscal year variant or posting period variant is not properly maintained or assigned.
  
  
  Solution:
  To resolve the WY095 error, follow these steps:
  
  
  Check the Period Entered:
  
  Verify that the period you entered is valid and exists in the fiscal year variant for the company code.
  
  
  Verify Fiscal Year Variant:  
  
  Go to transaction OB29 to check the fiscal year variant assigned to the company code.  
  Ensure the fiscal year variant covers the period you want to post or report on.
  
  
  
  Check Posting Period Variant:  
  
  Use transaction OB52 to check the posting period variant and the open posting periods for the company code.  
  Make sure the period you want to use is open for posting.
  
  
  
  Correct Period Format:  
  
  Ensure the period is entered in the correct format (usually a two-digit month or period number).  
  For example, period "01" for January, "12" for December.
  
  
  
  Adjust Period Settings if Needed:  
  
  If the period is not open, request the responsible finance or controlling team to open the period in OB52.  
  If the fiscal year variant is incorrect or incomplete, it may need to be adjusted by the system administrator or SAP consultant.
  
  
  
  Re-enter the Period:
  
  After verifying and correcting the above, re-enter the period and try the transaction again.
