• What is the cause and solution for SAP error message CNV_PE_IF017 - Table line parameter is missing or not unique (table parameter &1) ?

  The SAP error message CNV_PE_IF017 indicates that there is an issue with a table line parameter that is either missing or not unique. This error typically arises during data migration or conversion processes, particularly when using SAP's data migration tools or during the execution of programs that involve table parameters.
  Cause:
  
  Missing Parameter: The error can occur if a required parameter for a table line is not provided. This could be due to a configuration issue or an oversight in the data preparation phase.
  Non-Unique Parameter: If the parameter that is supposed to be unique has duplicate entries, the system will raise this error. This can happen if the data being migrated contains duplicates or if the logic used to generate unique identifiers is flawed.
  
  Solution:
  
  
  Check Data Preparation:
  
  Review the data being processed to ensure that all required parameters are included.
  Ensure that the data does not contain any missing values for the parameters that are mandatory.
  
  
  
  Ensure Uniqueness:
  
  Verify that the parameters intended to be unique do not have duplicate entries. You can use SQL queries or data analysis tools to identify duplicates in the dataset.
  If duplicates are found, you may need to modify the data to ensure that each entry is unique. This could involve adding additional identifiers or consolidating records.
  
  
  
  Review Configuration:
  
  Check the configuration settings of the migration tool or program being used. Ensure that all necessary mappings and settings are correctly defined.
  If you are using a custom program, review the code to ensure that it correctly handles the parameters and checks for uniqueness.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation related to the specific migration tool or process you are using. There may be specific guidelines or requirements that need to be followed.
  
  
  
  Testing:
  
  After making the necessary adjustments, run a test migration or conversion to see if the error persists. This will help confirm that the issue has been resolved.
