• What is the cause and solution for SAP error message W8135 - Input value & is not allowed ?

  SAP Error Message:
  
  W8135 - Input value & is not allowed
  
  Cause:
  The warning message W8135 occurs when a user enters a value in a field that is not permitted according to the validation rules defined in the SAP system. This typically happens in custom or standard transactions where input fields have restrictions on allowed values, such as fixed value lists, domain value checks, or validation exits.
  The placeholder & in the message is replaced by the actual input value that was rejected.
  
  Explanation:
  
  The system checks the input value against allowed values or validation logic.
  If the input value does not meet the criteria, the system issues this warning.
  It is a warning (W) message, so the user may be able to continue after acknowledging it, but the input is flagged as invalid.
  
  
  Common Scenarios:
  
  Entering a value not included in a fixed value list or domain.
  Input value violates a custom validation implemented via user exits, BADIs, or enhancement spots.
  Data entry in fields with predefined allowed values (e.g., material types, plant codes).
  Input value does not conform to format or range checks.
  
  
  Solution:
  
  
  Check Allowed Values:
  
  Verify the allowed values for the field in question.
  Use transaction SE11 to check the domain or data element associated with the field.
  Check if the field has fixed values or value tables restricting input.
  
  
  
  Correct Input:
  
  Enter a value that is allowed by the system.
  If unsure, use F4 help (value help) to select a valid value.
  
  
  
  Review Custom Validations:
  
  If the message arises due to custom code, review user exits, BADIs, or validation rules.
  Debug or check the logic that triggers the warning to understand why the value is rejected.
  
  
  
  Adjust Configuration (if applicable):
  
  If the business requirement has changed and the value should be allowed, update the configuration or domain fixed values accordingly.
  Transport changes to production after testing.
  
  
  
  Consult Documentation or SAP Notes:

  Additional Information:
  
  Message Class: Usually part of a specific message class related to the module or custom development.
  Transaction: The message can appear in various transactions depending on where the validation is implemented.
  Debugging: Use transaction SE91 to find the message text and class, then debug the program or enhancement where the message is triggered.
