• What is the cause and solution for SAP error message XSLT_TOOL028 - Blank line was inserted ?

  The SAP error message XSLT_TOOL028: Blank line was inserted typically occurs during the transformation process when using XSLT (Extensible Stylesheet Language Transformations) in SAP systems. This message indicates that a blank line has been inserted into the output, which can be due to various reasons related to the XSLT transformation logic or the input XML structure.
  Causes:
  
  
  Whitespace Handling: The XSLT transformation may be inserting blank lines due to how whitespace is handled in the input XML or the XSLT stylesheet. If there are unnecessary line breaks or spaces in the XML, the transformation might output blank lines.
  
  
  XSLT Logic: The logic defined in the XSLT stylesheet may inadvertently create blank lines. For example, if there are templates or instructions that do not produce any output but still generate line breaks.
  
  
  Output Formatting: The output method defined in the XSLT (e.g., text, XML, HTML) may affect how whitespace is treated, leading to blank lines in the output.
  
  
  Solutions:
  
  
  Review the XSLT Stylesheet: Check the XSLT code for any templates or instructions that might be causing blank lines. Look for <xsl:text> or <xsl:value-of> elements that might be outputting empty strings or unnecessary line breaks.
  
  
  Whitespace Control: Use the strip-space element in the XSLT to control whitespace handling. This can help eliminate unnecessary whitespace in the output:
  <xsl:strip-space elements="*"/>
  
  
  Trim Whitespace: If the input XML contains leading or trailing whitespace, consider using the normalize-space() function to trim whitespace in the XSLT transformation.
  
  
  Output Method: Ensure that the output method is appropriate for your needs. If you are generating XML, ensure that the formatting does not introduce blank lines.
  
  
  Debugging: Use debugging tools or logs to trace the transformation process and identify where the blank lines are being introduced. This can help pinpoint the exact location in the XSLT or input XML that needs to be addressed.
  
  
  Related Information:
  
  XSLT Documentation: Familiarize yourself with XSLT syntax and functions to better understand how to manipulate and format output.
  SAP Notes: Check SAP Notes or the SAP Community for any specific notes related to this error message, as there may be updates or patches that address known issues.
  Testing: Test the XSLT transformation with different input XML samples to see if the issue persists across various datasets.
  
  By addressing the above points, you should be able to resolve the issue related to the XSLT_TOOL028 error message in your SAP environment.
