Specifically, the error states that the first character in the Data Provider Class name cannot be a number. This is a common restriction in many programming languages and systems, including SAP.
  Cause:
  The error is triggered when the name of the Data Provider Class you are trying to use or create starts with a numeric character (0-9). In SAP, class names must adhere to specific naming conventions, which typically require that names start with a letter (A-Z, a-z) rather than a number.
  Solution:

  Identify the Class Name: Check the name of the Data Provider Class that is causing the error. The error message will usually provide the name in place of &1.
  
  
  Rename the Class: Change the first character of the class name from a number to a letter. For example, if the class name is 1MyClass, you could rename it to A1MyClass or any other valid name that starts with a letter.
  
  
  Update References: If the class name is referenced elsewhere in your code or configuration, make sure to update those references to reflect the new name.
  
  
  Test the Changes: After renaming the class and updating references, test the functionality to ensure that everything works as expected without any further errors.
  
  
  Related Information:
