  The SAP error message E2170, "Changes in the area of the expanded fields are not permitted," typically occurs when there is an attempt to modify fields that are part of an expanded structure in a data record. This can happen in various contexts, such as during data entry, updates, or when working with certain transactions or reports.
  Cause:
  
  Expanded Fields: The error is often related to the use of structures that have been expanded to include additional fields. In SAP, certain data structures are defined in a way that restricts changes to specific areas to maintain data integrity.
  Data Integrity Rules: The system enforces rules to prevent changes in areas that could lead to inconsistencies or corruption of data.
  Field Status: The field may be set to "display only" or "not editable" in the context you are working in.
  
  Solution:
  
  Check Field Status: Verify the field status in the transaction or program you are using. If the field is not meant to be edited, you will need to find an alternative way to achieve your goal.
  Review Custom Code: If you are working with custom programs or enhancements, check the code to ensure that it is not trying to modify fields that are restricted.
  Use Correct Transaction: Ensure you are using the correct transaction for the operation you are trying to perform. Some transactions may have restrictions on what can be edited.
