• What is the cause and solution for SAP error message SALV_X_API028 - Codelist is empty ?

  The SAP error message SALV_X_API028 indicates that a codelist is empty when using the SAP ALV (ABAP List Viewer) framework. This error typically occurs when you are trying to display a list or a dropdown that relies on a codelist, but the codelist has not been populated with any values.
  Cause:
  
  Empty Codelist: The most common cause is that the codelist you are trying to use has not been filled with any data. This can happen if the underlying data source is empty or if there is a logic error in the code that populates the codelist.
  Incorrect Configuration: The codelist might not be correctly configured in the program or the data retrieval logic might not be fetching the expected values.
  Data Filtering: If there are filters applied to the data retrieval process, it might result in an empty codelist if no records meet the criteria.
  
  Solution:
  
  Check Data Source: Verify that the data source for the codelist is populated. You can do this by checking the relevant database tables or data structures that are supposed to provide the values.
  Debugging: Use the ABAP debugger to step through the code where the codelist is being populated. Ensure that the logic is correct and that it is indeed fetching the expected values.
  Review Code Logic: Ensure that the code responsible for populating the codelist is executed correctly and that there are no conditions that might prevent it from running.
  Fallback Values: If applicable, consider implementing fallback values or default entries in the codelist to avoid the error when no data is available.
  Check Filters: If there are any filters applied to the data retrieval, review them to ensure they are not overly restrictive.
