  The SAP error message RSDDB722 indicates that there is an issue with the use of a high cardinality InfoObject in your data model. High cardinality refers to fields that have a large number of unique values, which can lead to performance issues or complications in certain contexts within SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  
  High Cardinality InfoObject: The error typically arises when you attempt to use an InfoObject that has a high cardinality in a context where it is not supported. This can happen in various scenarios, such as when creating queries, aggregations, or when using certain types of data modeling.
  Data Model Limitations: Some data models or query designs may not support high cardinality InfoObjects due to performance considerations or limitations in the underlying database structure.
  Incompatible Query Design: If you are trying to use a high cardinality InfoObject in a way that is not compatible with the query or report you are building, this error may occur.

  Review InfoObject Usage: Check the InfoObject that is causing the error. If it is indeed a high cardinality InfoObject, consider whether it is necessary for your query or report. If possible, replace it with a lower cardinality InfoObject.
  Aggregation: If you need to use the high cardinality InfoObject, consider aggregating the data at a higher level to reduce the cardinality. This can help improve performance and may resolve the error.
  Query Design: Revisit the design of your query. Ensure that you are not using high cardinality InfoObjects in contexts that do not support them, such as in certain filters or groupings.
  Data Modeling: If you are working with a data model, consider redesigning it to avoid high cardinality InfoObjects in critical areas. This may involve creating new InfoObjects or modifying existing ones.
