  The SAP error message RS_HCPR_MODEL108 indicates that there are missing join conditions for a join operation in a data model, specifically for the join identified by &1. This error typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when working with data models, queries, or transformations.
  Cause:
  The error is caused by one or more of the following reasons:
  
  Missing Join Conditions: The join between two or more tables does not have the necessary conditions defined, which are required to establish how the tables relate to each other.
  Incorrect Data Model Configuration: The data model may not be properly configured, leading to incomplete or incorrect join definitions.
  Changes in Data Sources: If the underlying data sources have changed (e.g., fields were renamed or removed), the join conditions may no longer be valid.
  Inconsistent Data Types: The fields used in the join conditions may have incompatible data types, which can prevent the join from being executed correctly.
  
  Solution:
  To resolve the RS_HCPR_MODEL108 error, you can follow these steps:
  
  
  Check Join Conditions:
