• 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.
  Check Field Requirements: Review the documentation or help text associated with the field to understand what values are acceptable.
  Consult with SAP Documentation: If you are unsure about the values that can be entered, refer to SAP's official documentation or help resources for guidance on the specific transaction or report you are using.
  Validation Rules: Ensure that any validation rules or settings in the configuration do not inadvertently restrict the values you are trying to enter.

  Transaction Codes: The error can occur in various transaction codes depending on the context (e.g., MM, SD, FI).
  SAP Notes: Check SAP Notes for any known issues or updates related to the specific transaction or module you are working with.
