SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_PE_CHECK - Check Framework messages for posting engine

• Message number: 082

• Message text: TRule exp. param &1 and assigned WL field &2 have different type + length

What causes this issue?

Within rule &V3& the result of transformation rule &V4& (passed via the
exporting parameter &V1& of the transformation rule) shall be moved to
the worklist field &V2&. This means that the content of the exporting
parameter &V1& is moved in the worklist field &V2&.
These two fields have a different data type and length.

• What is the cause and solution for SAP error message CNV_PE_CHECK082 - TRule exp. param &1 and assigned WL field &2 have different type + length ?

  The SAP error message CNV_PE_CHECK082 indicates a type and length mismatch between a transformation rule's expected parameter and the assigned field in the Worklist (WL). This error typically arises during data migration or transformation processes, particularly when using SAP's Data Migration tools or Conversion tools.
  Cause:
  
  
  Type Mismatch: The expected data type of the transformation rule parameter does not match the data type of the assigned Worklist field. For example, if the transformation rule expects a numeric value but the Worklist field is defined as a character string, this error will occur.
  
  
  Length Mismatch: Even if the data types match, the length of the data types may differ. For instance, if the transformation rule expects a string of length 10, but the Worklist field is defined as length 20, this can also trigger the error.
  
  
  Solution:
  
  
  Check Data Types: Review the data types of both the transformation rule parameter and the Worklist field. Ensure that they are compatible. You may need to adjust the data type of one of them to ensure they match.
  
  
  Adjust Lengths: If the data types are correct but the lengths differ, modify the length of the Worklist field or the transformation rule parameter to ensure they are the same.
  
  
  Modify Transformation Rules: If necessary, you can modify the transformation rules to accommodate the data types and lengths of the Worklist fields.
  
  
  Data Mapping: Ensure that the data mapping is correctly defined in the migration or transformation process. This includes checking any configuration settings that may affect how data types and lengths are interpreted.
  
  
  Testing: After making adjustments, run a test migration or transformation to ensure that the error is resolved.
