• What is the cause and solution for SAP error message CNV_PE_CHECK087 - TRule imp. param &1 and assigned WL field &2 have different type ?

  The SAP error message CNV_PE_CHECK087 indicates a type mismatch between the implementation parameter and the assigned WL (Worklist) field in a transformation rule. This error typically arises during data migration or transformation processes, particularly when using SAP's Data Migration tools or Conversion tools.
  Cause:
  The error occurs when:
  
  The data type of the implementation parameter (e.g., a variable or field used in a transformation rule) does not match the data type of the corresponding Worklist field.
  For example, if the implementation parameter is defined as a string (CHAR) but the Worklist field is defined as a numeric type (INT), this mismatch will trigger the error.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Types:
  
  Review the data types of both the implementation parameter and the Worklist field. Ensure that they are compatible.
  You can do this by navigating to the relevant transformation rule in the SAP system and checking the definitions.
  
  
  
  Modify Data Types:
  
  If you find a mismatch, you may need to change the data type of either the implementation parameter or the Worklist field to ensure they match.
  This may involve modifying the transformation rule or adjusting the data model.
  
  
  
  Update Transformation Rules:
  
  If the transformation logic is incorrect due to the type mismatch, update the transformation rules accordingly to ensure that the data types align.
  
  
  
  Test Changes:
  
  After making the necessary adjustments, test the transformation process again to ensure that the error is resolved.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidelines on data types and transformation rules.
