  The SAP error message LTR2_BASIS_CHECK523 with the description "Target cardinality value checked" typically occurs in the context of SAP's data modeling or data transformation processes, particularly when working with SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  This error generally indicates that there is a mismatch or inconsistency in the cardinality settings of a data model or transformation. Cardinality refers to the relationship between two entities in a data model, such as one-to-one, one-to-many, or many-to-many relationships. The error suggests that the target cardinality defined in the model does not align with the actual data or the expected configuration.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Cardinality Settings:
  
  Review the cardinality settings in your data model or transformation. Ensure that they are correctly defined according to the relationships between the source and target data.
  
  
  
  Validate Data:
  
  Check the data being processed to ensure that it adheres to the expected cardinality. For example, if you have defined a one-to-many relationship, ensure that the source data does not contain duplicate keys that would violate this relationship.
  
  
  
  Adjust Data Model:
  
  If necessary, adjust the data model to reflect the correct cardinality. This may involve changing the relationships or modifying the data structure.
  
  
  
  Re-run the Process:
  
  After making the necessary adjustments, re-run the data load or transformation process to see if the error persists.
