  The SAP error message RSPLFOX263 indicates that there is an issue with a non-key field in a DataStore Object (DSO) that is not supported in the context of a certain operation, typically related to the use of the DSO in a data flow or transformation.
  Cause:
  This error usually occurs when:
  
  Non-Key Field Usage: A non-key field is being used in a way that is not supported by the DSO. For example, it might be included in a transformation or a query where only key fields are expected.
  Data Model Configuration: The DSO might be incorrectly configured, or the data model might not align with the expected structure for the operation being performed.
  Incompatibility with InfoObjects: The InfoObjects associated with the DSO may not be properly defined or may have been changed, leading to inconsistencies.
  
  Solution:
  To resolve the RSPLFOX263 error, you can take the following steps:
  
  
  Check the DSO Structure:
