  SAP Error Message: WER380 - Expression constant
  1. Cause:
  The error message WER380 (and related messages WER381 to WER389) typically occurs during the generation or activation of ABAP code or when the system is evaluating expressions in the context of SAP Workflow, BRF+ (Business Rule Framework plus), or other rule-based engines.
  
  The message indicates that there is an invalid or incorrect constant expression in the code or rule.
  This usually happens when an expression expects a constant value but receives an invalid or malformed expression.
  It can also occur if the syntax of the expression is incorrect or if the expression contains unsupported characters or operators.
  In some cases, this error arises during the translation or parsing of expressions in workflow rules or decision tables.
  
  
  2. Solution:
  To resolve the WER380 error, follow these steps:
  
  
  Check the expression syntax:
  
  Review the expression or constant value causing the error.
  Ensure that the constant is correctly formatted and valid for the context.
  For example, if a numeric constant is expected, make sure it is a valid number without extra characters.
  
  
  
  Validate the rule or workflow:
  
  If the error occurs in a workflow or BRF+ rule, open the rule or expression editor.
  Use the syntax check or validation tools provided by SAP to identify the exact problem.
  
  
  
  Correct the constant value:
  
  Replace any invalid constants with valid ones.
  Remove unsupported characters or operators.
  
  
  
  Check for system notes or patches:
  
  Sometimes, this error can be caused by bugs in specific SAP versions.
  Check SAP Notes for any known issues related to WER380 and apply recommended patches or corrections.
  
  
  
  Debugging:
  
  If the error is not obvious, use the ABAP debugger or workflow trace to identify where the expression evaluation fails.
  
  
  
  Consult documentation:
