• What is the cause and solution for SAP error message /SCMTMS/COMMON112 - Cannot change maximum length of type &1; conflicts with existing codes ?

  The SAP error message /SCMTMS/COMMON112 indicates that there is an attempt to change the maximum length of a data type that conflicts with existing entries or codes in the system. This typically occurs in the context of customizing or modifying data types in the SAP Transportation Management System (TM) or other related modules.
  Cause:
  
  Data Type Modification: The error arises when you try to change the maximum length of a field in a table or structure that already has existing data that exceeds the new maximum length.
  Inconsistent Data: If there are existing entries in the database that do not comply with the new length restrictions, the system will prevent the change to maintain data integrity.
  Custom Development: If there are custom developments or enhancements that rely on the original length of the data type, changing it could lead to inconsistencies.
  
  Solution:
  
  
  Check Existing Data: Before changing the maximum length, check the existing data in the relevant table or structure to ensure that no entries exceed the new maximum length you want to set.
  
  You can use transaction codes like SE11 (Data Dictionary) or SE16 (Data Browser) to inspect the data.
  
  
  
  Adjust Data: If there are existing entries that exceed the new maximum length, you will need to either:
  
  Modify or truncate the existing data to fit within the new length.
  Delete the conflicting entries if they are no longer needed (ensure you have backups and that this is acceptable for your business process).
  
  
  
  Change the Length: Once you have ensured that there are no conflicts, you can proceed to change the maximum length of the data type in the Data Dictionary (SE11).
  
  Make sure to activate the changes after modifying the data type.
  
  
  
  Testing: After making the changes, perform thorough testing to ensure that the system behaves as expected and that there are no further issues related to data integrity.
  
  
  Consult Documentation: If you are unsure about the implications of changing the data type, consult SAP documentation or reach out to SAP support for guidance.
  
  
  Related Information:
  
  Data Dictionary (SE11): This is where you can view and modify data types, tables, and structures.
  Transport Requests: If you are making changes in a development environment, ensure that you transport the changes to the quality and production environments properly.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context or solutions.
  Backup: Always ensure you have a backup of your data before making structural changes to the database.
  
  By following these steps, you should be able to resolve the error and successfully change the maximum length of the data type in question.
