• What is the cause and solution for SAP error message SALV_IDA400 - Group &1 contains more than &2 group items ?

  The SAP error message SALV_IDA400 indicates that a specific group in your ALV (ABAP List Viewer) display contains more items than the allowed limit. This typically occurs when you are trying to display a large dataset in a grouped format, and the number of items in a group exceeds the predefined threshold.
  Cause:
  The error is triggered when:
  
  You are using the ALV Grid or ALV List display with grouping enabled.
  The number of items in a single group exceeds the maximum limit set by the system (denoted by &2 in the error message).
  This limit is often set to prevent performance issues or to maintain usability in the display.
  
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Reduce Group Size:
  
  Modify your selection criteria to limit the number of records being grouped. This can be done by filtering the data before it is passed to the ALV display.
  
  
  
  Change Grouping Logic:
  
  If possible, change the way you are grouping the data. For example, instead of grouping by a field that results in many items, consider grouping by a higher-level field that results in fewer items.
  
  
  
  Adjust ALV Settings:
  
  Check if there are any settings in your ALV configuration that allow you to increase the maximum number of items per group. This may require changes in the ALV configuration or the underlying data model.
  
  
  
  Paginate Data:
  
  If the dataset is too large, consider implementing pagination or displaying the data in smaller chunks rather than all at once.
  
  
  
  Review Documentation:
  
  Consult the SAP documentation or help resources for any specific configurations related to the ALV display that might help in adjusting the limits.
