• What is the cause and solution for SAP error message ESH_OM_PC002 - Model &2 must not start with Y or Z ?

  The SAP error message ESH_OM_PC002 indicates that a model name (in this case, represented by &2) must not start with the letters "Y" or "Z". This restriction is typically in place because models starting with these letters are often reserved for customer-specific developments or custom objects in SAP systems.
  Cause:
  
  Naming Convention: In many SAP systems, standard objects (like models, programs, etc.) are prefixed with letters A to X, while Y and Z are reserved for custom developments. This is a common practice to avoid conflicts between standard SAP objects and custom objects.
  Model Creation: When attempting to create or modify a model, if the name you provided starts with Y or Z, the system will throw this error to enforce the naming convention.
  
  Solution:
  
  Rename the Model: Change the name of the model you are trying to create or modify so that it does not start with Y or Z. Use a name that starts with A to X.
  Check Existing Models: If you are modifying an existing model, ensure that its name adheres to the naming conventions.
  Consult Documentation: If you are unsure about the naming conventions or the implications of changing a model name, consult your SAP documentation or your SAP administrator.
