• What is the cause and solution for SAP error message RSRTS_CDS028 - Could not resolve field &2 (ODP &1) ?

  The SAP error message RSRTS_CDS028 indicates that there is an issue with resolving a field in a Core Data Services (CDS) view when using the Operational Data Provisioning (ODP) framework. The error message typically appears in the context of reporting or data extraction processes, particularly when working with SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  The error can occur due to several reasons, including:
  
  
  Field Not Found: The specified field (&2) cannot be found in the CDS view or the underlying data model. This could be due to a typo in the field name or the field being removed or renamed in the data model.
  
  
  Inconsistent Data Model: Changes in the underlying data model (like changes in the database tables or views) that are not reflected in the CDS view can lead to this error.
  
  
  Transport Issues: If the CDS view was transported from one system to another (e.g., from development to production), there might be inconsistencies or missing objects in the target system.
  
  
  Authorization Issues: The user executing the query may not have the necessary authorizations to access the field or the CDS view.
  
  
  Incorrect ODP Configuration: The ODP settings may not be correctly configured, leading to issues in data extraction.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Field Name: Verify that the field name specified in the error message is correct and exists in the CDS view. You can do this by checking the definition of the CDS view in the ABAP Development Tools or SAP HANA Studio.
  
  
  Review Data Model Changes: If there have been recent changes to the underlying data model, ensure that the CDS view is updated accordingly. You may need to regenerate the CDS view or adjust its definition.
  
  
  Transport Consistency: If the issue arose after a transport, check that all dependent objects (like tables, views, and other CDS views) have been transported correctly and are available in the target system.
  
  
  Check Authorizations: Ensure that the user executing the query has the necessary authorizations to access the CDS view and the specific fields.
  
  
  ODP Configuration: Review the ODP configuration settings to ensure they are set up correctly. This includes checking the ODP source system and ensuring that the data source is active.
  
  
  Debugging: If the issue persists, consider debugging the query execution to identify where the resolution fails. This may involve looking at the SQL trace or using transaction codes like ST22 or SLG1 to check for runtime errors.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for any known issues related to the specific version of SAP you are using.
