  The SAP error message /PM0/AB_IBC_CNFG_I_C179 Maximum cardinality (&1) is not allowed for entity &2 typically occurs in the context of SAP Integrated Business Planning (IBP) or SAP Analytics Cloud (SAC) when there is a configuration issue related to the cardinality of entities in a model or planning area.
  Cause:
  
  Cardinality Violation: The error indicates that the maximum cardinality defined for a particular entity (e.g., a characteristic or key figure) is being exceeded. Cardinality refers to the number of instances of one entity that can be associated with instances of another entity.
  Model Configuration: This can happen if the model configuration allows for more instances of an entity than what is defined in the cardinality settings.
  Data Input Issues: If the data being loaded or processed exceeds the defined limits, this error can also occur.
  
  Solution:
  
  Review Cardinality Settings: Check the cardinality settings for the entities involved. Ensure that the maximum cardinality defined for the entity matches the expected data relationships.
  
  Go to the model configuration in IBP or SAC and review the cardinality settings for the relevant entities.
  
  
  Adjust Model Configuration: If necessary, adjust the model configuration to allow for a higher maximum cardinality if the business requirements demand it.
  Data Validation: Validate the data being loaded or processed to ensure it does not exceed the defined cardinality limits. This may involve cleaning or transforming the data before loading it into the model.
  Consult Documentation: Refer to the SAP documentation for specific guidelines on cardinality settings and best practices for configuring entities in your model.
