• Message number: 084

• Message text: TRule exp. param &1 and assigned WL field &2 have different 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 into the worklist field &V2&.
These two fields have the same data type, but a different length.

• What is the cause and solution for SAP error message CNV_PE_CHECK084 - TRule exp. param &1 and assigned WL field &2 have different length ?

  The SAP error message CNV_PE_CHECK084 indicates that there is a mismatch in the lengths of the expected parameters in a transformation rule (TRule) and the assigned field in the Worklist (WL). This typically occurs during data migration or transformation processes, particularly when using SAP's Data Migration tools or Conversion tools.
  Cause:
  The error arises when:
  
  The transformation rule (TRule) expects a parameter of a certain length, but the corresponding field in the Worklist (WL) has a different length.
  This can happen due to incorrect configuration of the transformation rules or mismatched data types between the source and target systems.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Transformation Rules:
  
  Review the transformation rules (TRules) defined in your data migration project.
  Ensure that the expected parameter lengths match the lengths of the fields in the Worklist.
  
  
  
  Adjust Field Lengths:
  
  If the TRule is correct, you may need to adjust the field lengths in the Worklist to match the expected lengths defined in the TRule.
  This may involve modifying the data structure in the source or target system.
  
  
  
  Data Type Consistency:
  
  Ensure that the data types of the parameters and fields are consistent. For example, if one is defined as a character type and the other as a numeric type, this could lead to length mismatches.
  
  
  
  Testing:
  
  After making adjustments, run a test migration to ensure that the error does not reoccur.
  Validate the data to ensure that it meets the expected formats and lengths.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or guides related to the specific data migration tool you are using for additional insights and best practices.
  
  
  
  Seek Support:
  
  If the issue persists, consider reaching out to SAP support or consulting with a technical expert who specializes in SAP data migration.
