The message typically states that the type of the existing substitution procedure cannot be changed from one type to another, which is indicated by the parameters &1, &2, and &3.

  Review the Substitution Procedure: Check the details of the existing substitution procedure to understand its current type and the implications of changing it. You can do this by navigating to the relevant transaction in SAP APO.
  Create a New Substitution Procedure: If you need a different type of substitution procedure, consider creating a new one instead of trying to change the existing one. This is often the recommended approach to avoid conflicts and maintain system integrity.

  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on substitution procedures and their types. This can provide insights into the limitations and best practices.
  Contact SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support for assistance. They can provide guidance based on the specific context of your system and configuration.
