• What is the cause and solution for SAP error message SALV_X_API088 - This operation is allowed for group header rows only ?

  The SAP error message SALV_X_API088 indicates that an operation you are trying to perform is restricted to group header rows in the context of the SAP ALV (ABAP List Viewer) framework. This typically occurs when you are attempting to manipulate or access data that is not a group header row, such as detail rows or other non-header rows.
  Cause:
  The error is triggered when:
  
  You are trying to perform an operation (like aggregation, summarization, or certain manipulations) that is only valid for group header rows.
  The code is incorrectly identifying the row type, or you are trying to apply a function that is not applicable to the current row context.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Row Type: Ensure that the operation you are trying to perform is indeed being applied to a group header row. You can do this by checking the row type before performing the operation.
  
  
  Modify Your Logic: If your logic is attempting to perform operations on detail rows, you may need to adjust your code to ensure that only group header rows are processed for that specific operation.
  
  
  Use Appropriate Methods: If you are using methods from the SALV API, make sure you are using the correct methods that are intended for group header rows. Review the documentation for the SALV classes and methods to ensure proper usage.
  
  
  Debugging: If you are unsure why the error is occurring, use debugging tools to step through your code and inspect the row types being processed. This can help you identify where the logic is failing.
  
  
  Consult Documentation: Review the SAP documentation for the ALV framework and the specific methods you are using to understand the expected input and behavior.
