• What is the cause and solution for SAP error message M8820 - All documents (&1) with same document number are selected ?

  The SAP error message M8820 indicates that there are multiple documents with the same document number in the system, which can lead to confusion or issues when trying to process or display these documents. This error typically occurs in the context of inventory management or material document processing.
  Cause:
  The primary cause of this error is that the system has detected multiple entries (documents) that share the same document number. This can happen due to various reasons, such as:
  
  Duplicate Document Creation: Multiple transactions may have been entered with the same document number, either due to user error or system issues.
  Data Migration Issues: If data was migrated from another system, it may have resulted in duplicate document numbers.
  Configuration Issues: Incorrect configuration in the document number assignment settings can lead to duplicates.
  
  Solution:
  To resolve the M8820 error, you can take the following steps:
  
  
  Identify Duplicate Documents:
  
  Use transaction codes like MB03 (Display Material Document) or MB51 (Material Document List) to search for and identify the documents with the same document number.
  Check the document types and the associated details to understand why duplicates exist.
  
  
  
  Analyze the Cause:
  
  Investigate how the duplicates were created. Look into transaction logs or user activities to determine if it was a manual error or a system issue.
  
  
  
  Delete or Correct Duplicates:
  
  If duplicates are found and confirmed to be erroneous, you may need to delete or reverse the unnecessary documents. This can be done using transaction codes like MBST (Cancel Material Document) or MIGO (Goods Movement) for reversing transactions.
  Ensure that you have the necessary authorizations and that you follow your organization's data management policies before deleting any documents.
  
  
  
  Prevent Future Duplicates:
  
  Review and adjust the configuration settings for document number assignment to prevent future occurrences of duplicates.
