• What is the cause and solution for SAP error message 5M263 - New entry sent with the same number as an existing entry ?

  The SAP error message 5M263, which states "New entry sent with the same number as an existing entry," typically occurs when there is an attempt to create a new record (such as a document, invoice, or master data) that has the same unique identifier (number) as an existing record in the system. This can happen in various modules, including finance, logistics, and others, depending on the context of the operation being performed.
  Cause:
  
  
  Duplicate Number Assignment: The system is trying to create a new entry with a number that is already assigned to an existing entry. This can happen if:
  
  The number range for the document type is not properly configured.
  Manual entry of a number that already exists in the database.
  A system error or misconfiguration that causes the same number to be generated for different entries.
  
  
  
  Number Range Overlap: If the number ranges for different document types overlap, it can lead to conflicts when creating new entries.
  
  
  Data Migration Issues: If data has been migrated from another system, there may be conflicts with existing numbers in the SAP system.
  
  
  Solution:
  
  
  Check Existing Entries: Verify if the number you are trying to use already exists in the system. You can do this by searching for the entry in the relevant transaction or table.
  
  
  Use a Different Number: If you are manually entering a number, try using a different number that does not conflict with existing entries.
  
  
  Review Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects) and check the configuration for the relevant number range object.
  Ensure that the number ranges are correctly defined and do not overlap.
  
  
  
  Adjust Number Range: If necessary, adjust the number range settings to allow for new entries. This may involve extending the range or creating a new number range.
  
  
  Consult with SAP Basis or Functional Team: If the issue persists, it may be necessary to involve your SAP Basis or functional team to investigate further, especially if it relates to system configuration or data integrity.
  
  
  Check for Custom Code: If there are any custom developments or enhancements in your SAP system, review them to ensure they are not causing the issue.
  
  
  Related Information:
  
  
  Transaction Codes: Depending on the context, you may need to use different transaction codes to investigate the issue, such as:
  
  SE11: Data Dictionary to check table definitions.

  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance.
