• What is the cause and solution for SAP error message /SAPAPO/MAT128 - Creation not possible (SNP supply profile &1 already exists) ?

  The SAP error message /SAPAPO/MAT128 Creation not possible (SNP supply profile &1 already exists) typically occurs in the SAP Advanced Planning and Optimization (APO) module, specifically within the Supply Network Planning (SNP) component. This error indicates that you are trying to create a supply profile that already exists in the system.
  Cause:
  The error is caused by the attempt to create a new SNP supply profile with a name that is already in use. Each supply profile must have a unique identifier, and if you try to create one with a name that matches an existing profile, the system will prevent the creation to avoid duplication.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Profiles:
  
  Go to the transaction code /SAPAPO/SNP1 (or the relevant transaction for managing SNP supply profiles).

  Use a Different Name:
  
  If you need to create a new supply profile, choose a different, unique name that does not conflict with existing profiles.
  
  
  
  Review Naming Conventions:
  
  Ensure that your naming conventions for supply profiles are clear and consistent to avoid future conflicts.
  
  
  
  Check for Transport Issues:
  
  If you are working in a development environment and transporting changes to production, ensure that the transport does not include profiles that may already exist in the target environment.
  
  
  
  Consult Documentation:
