This is common in various modules, including Material Management (MM) and Plant Maintenance (PM), where specific fields may require uppercase input for consistency and data integrity.
  Cause:
  The error is triggered when a user attempts to enter data into a field that only accepts uppercase letters, but the input contains lowercase letters or a mix of cases.

  Solution:
  To resolve the PMRP052 error, follow these steps:

  Use Uppercase Conversion: If you are copying and pasting data from another source, it may contain lowercase letters. Use a text editor or a spreadsheet application to convert the text to uppercase before pasting it into SAP.
  
  
  Keyboard Input: If you are typing directly into the field, ensure that the Caps Lock key is enabled or hold down the Shift key while typing to enter uppercase letters.
  
  
  Field Validation: If the field is part of a custom development or enhancement, check with your SAP development team to ensure that the validation rules are correctly implemented.
  
  
  User Training: If this error occurs frequently among users, consider providing training or documentation on the importance of using uppercase letters in specific fields.
