AR099 - Details

• The SAP error message AR099, which states "Field & contains invalid characters," typically occurs when a field in a transaction or data entry contains characters that are not allowed according to the system's validation rules. This can happen in various contexts, such as when entering data in a form, uploading data, or processing transactions.
  Causes:
  
  Invalid Characters: The field may contain special characters, spaces, or symbols that are not permitted. For example, if a field is supposed to contain only alphanumeric characters, any special characters (like @, #, $, etc.) would trigger this error.
  Field Length Exceeded: Sometimes, the error can also occur if the input exceeds the maximum length defined for that field.
  Incorrect Data Format: The data entered may not conform to the expected format (e.g., date formats, numeric formats).
  Custom Validation Rules: If there are custom validations implemented in the system, they may be rejecting the input based on specific criteria.
  
  Solutions:
