RSOS_SEARCH025 - Details

• The SAP error message RSOS_SEARCH025 indicates a discrepancy in the join cardinality between two conditions in a query. This typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when dealing with queries that involve multiple data sources or InfoProviders.
  
  Cause:
  The error arises when the cardinality (the relationship between two sets of data) of the conditions specified in the query does not match. For example, if one condition is expected to return a one-to-many relationship and the other is set up as a many-to-one relationship, the system will throw this error. This can happen due to:
  
  Inconsistent Data Model: The underlying data model may have been altered, leading to mismatched cardinalities.
  Incorrect Query Design: The query may have been designed incorrectly, with conditions that do not logically align.
  Changes in InfoObjects: If InfoObjects or InfoProviders have been modified or updated, it can lead to inconsistencies in cardinality.
