  The SAP error message RSOS_SEARCH149 indicates that there is a cardinality adjustment for a condition in a query or report. This typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when the system detects that the cardinality (the relationship between two sets of data) of a condition has changed.

  Data Model Changes: The cardinality of a condition may change due to modifications in the underlying data model, such as changes in InfoObjects, InfoProviders, or transformations.
  Query Design Changes: If a query is modified (e.g., adding or removing filters, changing joins), it can lead to a change in cardinality.

  Review Query Design: Check the design of the query or report where the error occurs. Ensure that the conditions and filters are set correctly and that they align with the data model.
  Check Data Model: Review any recent changes made to the data model, including InfoObjects, InfoProviders, and transformations. Ensure that they are correctly defined and that relationships are properly established.

  Adjust Cardinality Manually: If necessary, you can manually adjust the cardinality settings in the query designer or data model to reflect the correct relationships.
  Consult Documentation: Refer to SAP documentation or notes related to cardinality adjustments for specific guidance on handling this error.
