• What is the cause and solution for SAP error message FDT_CP_MSG010 - Multiple keys are not supported ?

  The SAP error message FDT_CP_MSG010: Multiple keys are not supported typically occurs in the context of using the SAP Fiori Design Studio or when working with certain data models in SAP applications. This error indicates that the system is encountering a situation where multiple keys are being used in a context that only supports a single key.
  Cause:
  
  Data Model Configuration: The error often arises when a data model is configured to use multiple keys, but the underlying framework or application logic only supports a single key.
  Incompatible Data Sources: If you are trying to bind a data source that has multiple keys to a UI element that expects a single key, this error can occur.
  Incorrect Mapping: There may be an issue with how the keys are mapped in the application, leading to confusion in the data retrieval process.
  
  Solution:
  
  Review Data Model: Check the data model configuration to ensure that it is set up to use a single key. If multiple keys are defined, consider consolidating them into a single key if possible.
  Adjust UI Bindings: If you are working with UI elements, ensure that they are bound to a single key. Review the binding expressions and adjust them to reference only one key.
  Modify Data Source: If the data source inherently requires multiple keys, consider modifying the data source or creating a view that presents a single key for the application to use.
  Consult Documentation: Refer to the SAP documentation for the specific application or framework you are using to understand the key requirements and limitations.
  Debugging: Use debugging tools to trace the data flow and identify where the multiple keys are being introduced. This can help pinpoint the exact location of the issue.
