  Error Message
  WER143: XSLT program &1 is not valid
  
  &1 is a placeholder for the name of the XSLT program that is reported as invalid.
  
  
  Cause
  This error occurs when the SAP system tries to use an XSLT program (stylesheet) that is either:
  
  Not properly activated in the system.
  Contains syntax errors or is not well-formed XML.
  Missing or corrupted in the SAP repository.
  The XSLT program is incompatible with the current SAP system version or the transformation engine.
  The XSLT program is referenced incorrectly or the transport/import of the XSLT program was incomplete or faulty.
  
  
  Explanation
  SAP uses XSLT programs for XML transformations, for example in IDocs, PI/PO, or other XML processing scenarios. The XSLT program must be valid and active in the SAP system to be used successfully.
  If the XSLT program is invalid, the system cannot perform the transformation, resulting in this error.
