  SAP Error Message:
  
  WTYMP015 – Entry not allowed. Use only letters A-Z and numbers 0-9
  
  Cause:
  This error occurs when an input field in SAP expects an alphanumeric entry restricted to uppercase letters (A-Z) and digits (0-9) only, but the user has entered invalid characters. Invalid characters can include:
  
  Lowercase letters (a-z)
  Special characters (e.g., @, #, $, %, &, *, etc.)
  Spaces or other non-alphanumeric symbols
  
  The system validation for this field enforces strict input rules to maintain data integrity and consistency.
  
  Solution:
  
  Check the input: Ensure that the data you are entering contains only uppercase letters (A-Z) and digits (0-9).
  Remove invalid characters: Delete any lowercase letters, spaces, or special characters.
  Convert lowercase to uppercase: If you have lowercase letters, convert them to uppercase before entering.
  Follow field-specific instructions: Some fields may have additional restrictions or length limits; verify these in the field documentation or help.
  Use SAP standard input methods: Avoid copy-pasting from external sources that might introduce hidden or special characters.
  
  
  Related Information:
  
  This message is commonly encountered in fields such as material numbers, batch numbers, customer/vendor codes, or other master data fields where strict alphanumeric input is required.
  The validation is typically implemented via domain or data element checks in the ABAP Dictionary.
  If you are a developer or system administrator, you can check the domain or data element associated with the field to see the allowed character set.
  If the error occurs unexpectedly or for valid input, check for custom validations or user exits that might be enforcing additional restrictions.
  Refer to SAP Notes or documentation for the specific module or transaction if the problem persists.
  
  
  Summary:
