Smart SAP Assistant

• What is the cause and solution for SAP error message /PM0/3FW_MESSAGES091 - Customer variant &1 must start with 'Y', 'Z', or '/' ?

  The SAP error message /PM0/3FW_MESSAGES091 indicates that a customer variant (likely a variant of a report or transaction) must start with specific characters: 'Y', 'Z', or '/'. This is a common restriction in SAP systems where custom objects (like variants, programs, or transactions) are required to follow certain naming conventions to differentiate them from standard SAP objects.
  Cause:
  
  Naming Convention: In SAP, standard objects typically do not start with 'Y', 'Z', or '/'. The system enforces this rule to prevent naming conflicts between custom and standard objects.
  Incorrect Variant Name: The variant name you are trying to use does not comply with the required naming convention.
  
  Solution:
  
  Rename the Variant: Change the name of the customer variant to start with 'Y', 'Z', or '/'. For example, if your current variant name is CUSTOM_VARIANT, you could rename it to Y_CUSTOM_VARIANT or Z_CUSTOM_VARIANT.
  Check Existing Variants: If you are trying to use an existing variant, ensure that it adheres to the naming convention. If it does not, you will need to create a new variant with the correct name.
  Consult Documentation: If you are unsure about the naming conventions or how to create a variant, refer to the SAP documentation or consult with your SAP administrator.
  
  Related Information:
  
  SAP Customization: Custom objects in SAP are typically prefixed with 'Y' or 'Z' to distinguish them from standard SAP objects. This is a best practice in SAP development.
  Transaction Variants: Variants are often used in transaction codes to save specific selections or settings. Ensure that any variants you create or modify follow the naming conventions.
  Error Handling: If you encounter this error frequently, consider implementing a naming convention policy within your organization to avoid similar issues in the future.
  
  If you continue to experience issues after following these steps, it may be helpful to consult with your SAP support team or refer to SAP Notes for more specific guidance related to your system version.
