How To Fix RS2HANA_VIEW030 - Check external SAP HANA view for BW object consistency

RS2HANA_VIEW030 - Overview

• Message type: E = Error

• Message class: RS2HANA_VIEW - HANA Views for BW Objects

• Message number: 030

• Message text: Check external SAP HANA view for BW object consistency

&DESCRIPTION&
This check is restricted to the external SAP HANA views of the SAP HANA
content package specified in transaction SPRO.
The external SAP HANA view and corresponding authorization objects are
checked for the BW object.
If the external SAP HANA View should exist according to the metadata
information of the object, the existence of the external SAP HANA view
and the consistency of the latter with the current metadata are checked.
Example: A user has modified the external SAP HANA view by adding a
measure to the view. This would make the BW object and the corresponding
external SAP HANA view inconsistent.
If the external SAP HANA view should not exist, the existence of the
external SAP HANA view is checked.
BW authorizations for the BW object are also checked to see if all
necessary SAP HANA privileges are in place. This check does not evaluate
if the values of the BW authorizations have been modified however. The
table with the authorization information for the SAP HANA privileges
therefore needs to be updated.

How to fix this error?

The repair function will delete or re-deploy the external SAP HANA view
and the corresponding SAP HANA privileges according to the current
settings of the BW objects.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

  Missing Fields: The BW object may reference fields that no longer exist in the HANA view.
  Data Type Mismatches: If the data types of fields in the HANA view do not match those expected by the BW object, it can cause errors.
  Incorrect Mapping: The mapping between the BW object and
