• Message type: E = Error

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

• Message number: 088

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

What causes this issue?

Rule &V3& contains transformation rule &V4&.
This transformation rule has an importing parameter &V1&. When calling
the transformation rule this importing parameter is filled with the
content of the worklist field &V2&.
These two fields have the same data type, but a different length.

CNV_PE_CHECK088 - Details

• The SAP error message CNV_PE_CHECK088 indicates that there is a mismatch in the lengths of the implementation parameter and the assigned field in a transformation rule (TRule). This typically occurs during data migration or transformation processes, particularly when using the SAP Data Migration Cockpit or similar tools.
  
  Cause:
  The error arises when:
  
  The length of the implementation parameter (denoted as &1) does not match the length of the corresponding field (denoted as &2) in the target structure or table.
  This can happen if the data types or lengths defined in the transformation rules do not align with the definitions in the target data model.
  
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the Transformation Rule:
  
  Open the transformation rule where the error is occurring.
  Identify the implementation parameter and the assigned field that are causing the mismatch.
  
  
  
  Verify Lengths:
  
  Compare the lengths of the implementation parameter and the assigned field.
  Ensure that both lengths are compatible. If the implementation
