  Solution:
  
  Review Structure Definition: Check the definition of the structure mentioned in the error message. Identify the key fields and assess whether all of them are necessary. If possible, reduce the number of key fields to comply with SAP's limitations.
  Modify Data Model: If the structure is part of a data model, consider redesigning the model to use fewer key fields. This may involve consolidating fields or changing the way data is organized.
  Consult Documentation: Refer to SAP documentation or notes related to the specific structure and its limitations. This can provide insights into the maximum number of key fields allowed.
  Engage SAP Support: If the issue persists or if you are unsure about how to proceed, consider reaching out to SAP support for assistance. They can provide guidance based on the specific context of your implementation.
