• What is the cause and solution for SAP error message SDDIC_ADT_DDLA040 - Names may not contain only the '_' character ?

  The SAP error message SDDIC_ADT_DDLA040 indicates that a name (likely for a data element, domain, or similar object) is invalid because it consists solely of the underscore character (_). In SAP, naming conventions are important, and certain restrictions apply to ensure that names are meaningful and adhere to the system's standards.
  Cause:
  The error occurs when you attempt to create or modify an object in the ABAP Dictionary (ADT) with a name that does not meet the naming conventions. Specifically, names cannot consist solely of the underscore character, as this does not provide any meaningful identification for the object.
  Solution:
  To resolve this error, you should rename the object in question to ensure that it contains valid characters and is not just an underscore. Here are some steps you can take:
  
  
  Choose a Meaningful Name: Select a name that reflects the purpose of the object. For example, instead of using _, you might use my_object_name or data_element_1.
  
  
  Follow Naming Conventions: Ensure that the name adheres to SAP's naming conventions:
  
  Names should start with a letter (A-Z, a-z).
  They can contain letters, numbers (0-9), and underscores (_).
  Avoid using special characters or starting with a number.
  
  
  
  Check for Existing Objects: If you are renaming an existing object, make sure that the new name does not conflict with existing objects in the system.
  
  
  Test the Changes: After renaming, test the object to ensure that it functions as expected and that the error no longer appears.
  
  
  Related Information:
