• What is the cause and solution for SAP error message O0306 - Entry of generic values not permitted for &1 &2 ?

  The SAP error message O0306 ("Entry of generic values not permitted for &1 &2") typically occurs when you are trying to enter a generic value (like a wildcard) in a field that does not allow it. This can happen in various contexts, such as when working with selection screens, reports, or transactions where specific values are expected.
  
  Cause:
  
  Generic Values: The error is triggered when a user attempts to input a generic value (e.g., using a wildcard like * or ?) in a field that requires a specific value.
  Field Restrictions: Certain fields in SAP are designed to accept only specific values, and using a generic value violates these restrictions.
  Data Type Mismatch: The field may be expecting a certain data type or format that does not accommodate generic values.
  
  
  Solution:
  
  Use Specific Values: Instead of entering a generic value, provide a specific value that meets the criteria of the field.
