How To Fix RS2HANA_VIEW182 - &1: Hierarchy &2 not valid for SAP HANA. Multiple parents in NotAssigned.

RS2HANA_VIEW182 - Overview

• Message type: E = Error

• Message class: RS2HANA_VIEW - HANA Views for BW Objects

• Message number: 182

• Message text: &1: Hierarchy &2 not valid for SAP HANA. Multiple parents in NotAssigned.

If the hierarchy contains non-basic characteristic nodes, the names of
these nodes are included in the master data values and the hierarchy has
the property 'do not suppress unassigned nodes', the unsupported case of
multiple parents will occur at runtime (if the hierarchy is displayed
and includes the unassigned nodes).
In order to prevent this from occurring, this type of hierarchy is not
allowed.

RS2HANA_VIEW182 - Details

• The SAP error message RS2HANA_VIEW182 indicates that there is an issue with a hierarchy in SAP BW (Business Warehouse) that is being used in conjunction with SAP HANA. Specifically, the error message states that the hierarchy is not valid for SAP HANA due to the presence of multiple parents in the "NotAssigned" node.
  
  Cause:
  
  
  Hierarchy Structure: In SAP BW, hierarchies can have multiple parent nodes. However, in SAP HANA, the hierarchy structure must adhere to certain rules, including that each node can only have one parent. The error occurs when a node in the hierarchy has multiple parents, which is not allowed in HANA.
  
  
  Data Model Issues: The hierarchy might have been defined or modified in a way that violates the constraints required by HANA. This could happen during data modeling or when migrating from BW to HANA.
  
  
  Inconsistent Data: There may be inconsistencies in the data that lead to multiple parent assignments for
