  Solution:
  To resolve this error, you should:
  
  
  Check the Material Number: Ensure that the material number you are trying to create or modify is entirely in uppercase letters. For example, if you have "material123", change it to "MATERIAL123".
  
  
  Modify Input: If you are entering the material number manually, simply re-enter it in uppercase. If the material number is being generated programmatically, ensure that the code generating the material number converts it to uppercase.
  
  
  Validation: If you are using a file upload or an interface to create materials, ensure that the data being uploaded does not contain lowercase characters. You may need to preprocess the data to convert all material numbers to uppercase before uploading.
  
  
  Check Configuration: If you are consistently facing this issue, check the configuration settings in your SAP system to confirm the allowed character set for material numbers. This can usually be found in the material master settings.
  
  
  Related Information:

  SAP Documentation: Refer to the SAP Help Portal or your organization's SAP documentation for more details on material master data and naming conventions.
  
  
  User Exits and BAdIs: If you are developing custom solutions or enhancements, consider implementing user exits or BAdIs (Business Add-Ins) to enforce the uppercase requirement programmatically.
