  The SAP error message SALV_X_API070 indicates that there are duplicate codes in a codelist that is being processed. This typically occurs when you are working with the SAP ALV (ABAP List Viewer) framework, particularly when using the SALV (Simple ALV) classes to display data.
  Cause:
  The error is caused by the presence of duplicate entries in the codelist that you are trying to use. This can happen if:
  
  The data source for the codelist contains duplicate values.
  The logic used to populate the codelist does not properly filter out duplicates.
  There is an issue in the configuration or data definition that allows for duplicate entries.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Data Source: Review the data source that is being used to populate the codelist. Ensure that it does not contain duplicate entries. You can do this by querying the database table or internal table that is being used.
  
  
  Remove Duplicates: If duplicates are found, you can either:
  
  Modify the data source to eliminate duplicates.

  SORT itab BY fieldname.
  DELETE ADJACENT DUPLICATES FROM itab COMPARING fieldname.
  
  
  Check Codelist Configuration: If you are using a predefined codelist, check the configuration settings to ensure that it is set up correctly and does not allow duplicates.
  
  
  Debugging: If the issue persists, consider debugging the code to trace where the codelist is being populated and identify the source of the duplicates.
