• What is the cause and solution for SAP error message CNV_PE_CHECK336 - Company code &1: Source period &2 (ledger &3) is not supported ?

  The SAP error message CNV_PE_CHECK336 indicates that there is an issue with the source period for a specific company code and ledger during a data migration or conversion process. This error typically arises in the context of the SAP Conversion or Migration projects, particularly when using tools like the SAP S/4HANA Migration Cockpit or other data migration tools.
  Cause:
  The error message can be caused by several factors:
  
  Unsupported Period: The source period specified in the migration process is not supported for the given company code and ledger. This could be due to the period being closed or not being defined in the system.
  Configuration Issues: The ledger configuration may not allow postings for the specified period, or the period may not be open for the company code in question.
  Data Consistency: There may be inconsistencies in the data being migrated, such as missing entries or incorrect mappings.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Period Status:
  
  Go to the transaction code OB52 (Open and Close Posting Periods) and verify if the source period for the specified company code and ledger is open. If it is closed, you may need to open it temporarily for the migration process.
  
  
  
  Review Ledger Configuration:
  
  Ensure that the ledger configuration allows postings for the specified period. You can check this in the configuration settings for the ledger.
  
  
  
  Adjust Migration Data:
  
  If the source period is indeed not supported, consider adjusting the migration data to use a valid period that is open and supported for the company code and ledger.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation related to the migration process you are using. There may be specific guidelines or prerequisites that need to be followed.
