• What is the cause and solution for SAP error message W0105 - Mark one country schema as standard ?

  SAP Error Message:
  W0105 - Mark one country schema as standard
  
  
  Cause:
  This warning message appears when you have defined multiple country-specific schemas in the system, but none of them is marked as the standard country schema. In SAP, one country schema must be designated as the standard to ensure that the system knows which schema to use as the default for various processes, such as tax calculations, reporting, or legal compliance.
  
  Explanation:
  
  Country Schema: A country schema in SAP defines the rules and settings specific to a country, such as tax codes, reporting requirements, and legal regulations.
  When multiple country schemas exist, SAP requires one to be marked as the standard to avoid ambiguity.
  Without a standard country schema, certain processes may fail or behave unpredictably because the system does not know which schema to apply by default.
  
  
  
  Solution:
  
  
  Identify the country schemas defined in your system:
  
  Use transaction code OBYZ (for Financial Accounting) or the relevant IMG path
