• What is the cause and solution for SAP error message RSWADMDERR2126 - XML comments cannot contain -- ?

  The SAP error message RSWADMDERR2126 indicates that there is an issue with XML comments in the context of SAP's ABAP Web Dynpro or other XML-related processing. Specifically, the error states that XML comments cannot contain the sequence --, which is not allowed in XML syntax.
  Cause:
  In XML, comments are defined using the syntax <!-- comment -->. However, the sequence -- cannot appear within the comment itself, as it would be interpreted as the end of the comment. If your XML contains a comment that looks like this:
  <!-- This is a comment with -- inside -->

  Solution:
  To resolve this error, you need to check the XML content that is being processed and ensure that no comments contain the -- sequence. Here are the steps to fix the issue:
  
  
  Locate the XML Source: Identify the XML file or string that is causing the error. This could be part of a configuration, data input, or generated output.
  
  
  Edit the Comments: Review the comments in the XML and modify any that contain the -- sequence. For example, change:
  <!-- This is a comment with -- inside -->
  to:
  <!-- This is a comment with a different phrasing -->
  
  
  Validate the XML: After making changes, validate the XML to ensure that it is well-formed and does not contain any other syntax errors.
  
  
  Test the Changes: Re-run the process that was generating the error to confirm that the issue has been resolved.
  
  
  Related Information:
  
  XML Syntax Rules: Familiarize yourself with XML syntax rules, especially regarding comments. Comments should not contain -- and should be properly closed.
  SAP Documentation: Refer to SAP documentation for any specific guidelines related to XML processing in your version of SAP.
  Debugging Tools: Use XML validation tools or editors that can help identify syntax errors in your XML files.
  
  By following these steps, you should be able to resolve the error and ensure that your XML comments comply with the required syntax.
