• What is the cause and solution for SAP error message /STTPEC/MC_MD112 - You can assign national code &1 with type &2 only once. ?

  The SAP error message /STTPEC/MC_MD112 indicates that there is an issue with the assignment of a national code to a specific type in the system. This error typically arises in the context of master data management, particularly when dealing with material master records or similar entities where national codes are used.
  Cause:
  The error occurs when you attempt to assign a national code (represented by &1) to a type (represented by &2) that has already been assigned. In other words, the system is enforcing a rule that a national code can only be linked to a specific type once. This is often a data integrity constraint to prevent duplicate assignments that could lead to inconsistencies in reporting or processing.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Assignments:
  
  Use transaction codes like SE16 or SE11 to view the relevant database tables (e.g., /STTPEC/MC_MD or similar) to check if the national code is already assigned to the type in question.
  Identify any existing records that may be causing the conflict.
  
  
  
  Modify or Remove Existing Assignments:
  
  If you find that the national code is already assigned and you need to change it, you may need to remove the existing assignment before you can assign it again.
  Ensure that you have the necessary authorizations to make changes to the master data.
  
  
  
  Create a New Assignment:
  
  If the national code needs to be assigned to a different type, ensure that you are using a unique combination that has not been previously assigned.
  
  
  
  Consult Documentation:
  
  Review any relevant SAP documentation or configuration guides that pertain to national codes and their assignments to ensure compliance with business rules.
  
  
  
  Contact Support:
  
  If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with an SAP expert who can provide further assistance.

  Data Integrity: Understand the importance of data integrity in SAP and how it affects reporting and operational processes.
  Custom Development: If your organization has custom developments or enhancements, check if any custom logic is affecting the assignment of national codes.
