  The SAP error message SPRX101 indicates that a certain character (in this case, 'X') is not permitted as the first character in a specific context, typically related to enhancements or modifications in the SAP system. This error often arises when you are trying to create or modify an object (like a program, function module, or enhancement) and the naming conventions are not being followed.
  Cause:

  Solution:
  
  Rename the Object: Change the name of the object you are trying to create or modify so that it does not start with 'X'. Use a valid naming convention that adheres to SAP's guidelines.
  Check Naming Conventions: Familiarize yourself with the naming conventions for the specific type of object you are working with. For example, standard naming conventions often allow letters (A-Z), numbers (0-9), and underscores (_), but certain characters may be restricted.
  Use SAP Transaction Codes: If you are working within a specific transaction (like SE80 for Object Navigator), ensure that you are following the naming rules as per the documentation or guidelines provided for that transaction.
  
  Related Information:
