• What is the cause and solution for SAP error message M&126 - Variant names beginning with % reserved for system ?

  The SAP error message M&126, which states "Variant names beginning with % reserved for system," typically occurs when a user attempts to create or use a variant name that starts with the "%" character. In SAP, certain characters are reserved for system use, and using them in user-defined names can lead to conflicts or unexpected behavior.
  Cause:
  The primary cause of this error is the attempt to create a variant (for example, for reports or selection screens) with a name that begins with the "%" character. SAP reserves names starting with "%" for internal system use, and therefore, they cannot be used by end-users.
  Solution:
  To resolve this error, you should:
  
  
  Rename the Variant: Choose a different name for your variant that does not start with the "%" character. Ensure that the new name adheres to the naming conventions and does not conflict with reserved names.
  
  
  Check Existing Variants: If you are trying to access an existing variant, verify that it does not start with the "%" character. If it does, you will need to rename it.
  
  
  Follow Naming Conventions: When creating new variants, follow the standard naming conventions in SAP, which typically allow alphanumeric characters and certain special characters, but avoid using reserved characters.
  
  
  Related Information:
  
  SAP Documentation: Refer to the SAP Help Portal or the specific documentation for the module you are working with for more details on naming conventions and reserved characters.
  Transaction Codes: If you are working with variants in reports, you might be using transaction codes like SE38 (ABAP Editor) or SA38 (Execute Report). Ensure you are familiar with the variant management features in these transactions.
  User Authorizations: Ensure that you have the necessary authorizations to create or modify variants, as sometimes restrictions can lead to confusion regarding naming issues.
  
  By following these guidelines, you should be able to avoid the M&126 error and successfully create and manage your variants in SAP.
