• What is the cause and solution for SAP error message SALV_X_API128 - No aggregation for column &1 defined ?

  The SAP error message SALV_X_API128 indicates that there is no aggregation defined for a specific column in an ALV (ABAP List Viewer) report. This typically occurs when you are trying to use aggregation features in an ALV grid, but the specified column does not have any aggregation settings defined.
  Cause:
  
  Missing Aggregation Definition: The column you are trying to aggregate does not have an aggregation method defined in the ALV configuration.
  Incorrect Column Type: The column may not be of a type that supports aggregation (e.g., non-numeric types).
  ALV Configuration Issues: There may be issues in the way the ALV is configured in your ABAP program.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Define Aggregation for the Column:
  
  Ensure that the column in question has an aggregation method defined. You can do this by using the setAggregation method in your ALV configuration.
  Example:
  DATA(lo_alv) = NEW cl_salv_table( ... ).
  DATA(lo_columns) = lo_alv->get_columns( ).
  lo_columns->get_column( 'COLUMN_NAME' )->set_aggregation( cl_salv_columns_table=>aggregation_sum ).
  
  
  
  
  Check Column Data Type:
  
  Verify that the data type of the column is appropriate for aggregation. For example, numeric types (like integers or decimals) can be aggregated, while character types cannot.
  
  
  
  Review ALV Configuration:
  
  Check the overall configuration of your ALV report to ensure that all necessary settings are correctly applied. This includes checking the field catalog and ensuring that the column is included and properly configured.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the ALV report to trace where the aggregation is being set and identify any discrepancies.
