  Cause:
  This error arises when you attempt to define key fields for a field string that does not support key fields. Field strings are used to group fields together, but not all field strings can have key fields associated with them.

  Solution:

  Use Appropriate Data Structure: If you need to define key fields, consider using a different data structure that allows for key fields. For example, if you are working with a database table or a structure that requires key fields, ensure that you are using a standard table or a structure that supports key definitions.
  
  
  Modify the Data Model: If you have control over the data model, you may need to modify it to ensure that the field string can accommodate key fields, or alternatively, create a new field string that is designed to support key fields.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on the specific data structure you are working with. This can provide insights into the limitations and requirements for defining key fields.
  
  
  Seek Help from SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support or consulting with a colleague who has experience with ABAP Dictionary and data modeling in SAP.
