• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK187 - Transient Flds Incl. &1 not in RDS Entity &2 datatype; Regenerate in SEGW ?

  The SAP error message CFD_REGISTRY_CHECK187 indicates that there is a mismatch between the transient fields defined in your Data Model and the corresponding fields in the RDS (Rapid Deployment Solution) entity. This typically occurs in the context of OData services and the Service Builder (SEGW) when you are trying to generate or regenerate an OData service.
  Cause:
  
  Mismatch in Field Definitions: The transient fields included in your data model are not defined in the RDS entity. This can happen if the data model was modified after the initial generation of the OData service.
  Changes in the Data Model: If you have added or removed fields in the transient data model without updating the corresponding RDS entity, this error can occur.
  Inconsistent Metadata: The metadata of the OData service may not be in sync with the underlying data model due to changes made in the SEGW transaction.
  
  Solution:
  
  
  Regenerate the OData Service:
  
  Open the Service Builder (transaction SEGW).
  Select the relevant project.
  Right-click on the project and choose "Regenerate" to regenerate the service. This will update the service definition and align it with the current data model.
  
  
  
  Check Transient Fields:
  
  Review the transient fields defined in your data model and ensure they are correctly mapped to the RDS entity.
  If there are fields that are no longer needed, consider removing them from the transient data model.
  
  
  
  Update RDS Entity:
  
  If you have added new transient fields, ensure that these fields are also defined in the RDS entity. You may need to update the RDS entity definition accordingly.
  
  
  
  Check for Errors in the Data Model:
  
  Validate the data model for any inconsistencies or errors that may be causing the mismatch.
  
  
  
  Test the OData Service:
  
  After regeneration, test the OData service to ensure that it is functioning correctly and that the error has been resolved.
  
  
  
  Related Information:
  
  Transaction SEGW: This is the Service Builder transaction where you can create and manage OData services.
  Transient Fields: These are fields that are not stored in the database but are used for temporary data handling in the context of OData services.
  RDS (Rapid Deployment Solutions): These are pre-packaged solutions provided by SAP that include best practices and templates for rapid implementation.
