• What is the cause and solution for SAP error message /MOC/OBJECT237 - Reference object &1, ID &2, system &3, occurs more than once ?

  The SAP error message /MOC/OBJECT237 indicates that a reference object is being duplicated in the system. This typically occurs in the context of Master Data Management or Object Management in SAP, where the system expects unique identifiers for certain objects, but finds multiple entries that match the criteria.
  Cause:
  The error is triggered when:
  
  There are multiple entries in the database for the same reference object with the same ID in the specified system.
  The system is trying to process or retrieve a reference object, but it encounters more than one instance of that object, which violates the uniqueness constraint.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify Duplicates:
  
  Use transaction codes like SE16 or SE11 to query the relevant database table where the reference objects are stored. Look for entries that match the object ID and system.
  You can also use SQL queries to find duplicates based on the criteria provided in the error message.
  
  
  
  Data Cleanup:
  
  Once you identify the duplicates, you need to determine which entries are valid and which can be deleted or merged.
  If duplicates are not needed, you can delete the unnecessary entries. Ensure you have backups or have confirmed that the data is not required before deletion.
  
  
  
  Check Configuration:
  
  Review the configuration settings related to the object management or master data management to ensure that the system is set up to prevent duplicates in the future.
  Implement validation rules or checks to ensure that new entries are unique.
