• What is the cause and solution for SAP error message PVS0C351 - Limit the cardinality ?

  The SAP error message PVS0C351, which states "Limit the cardinality," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when there is an issue related to the cardinality of data models, particularly in the context of InfoObjects, queries, or data modeling.
  Cause:
  
  Cardinality Issues: This error usually arises when the cardinality of a relationship between two objects (like InfoObjects or tables) exceeds the allowed limits. Cardinality refers to the uniqueness of data in a relationship. For example, a one-to-many relationship is valid, but a many-to-many relationship might not be allowed in certain contexts.
  Data Model Design: The data model may not be designed correctly, leading to excessive relationships or incorrect configurations that violate cardinality rules.
  Query Design: If you are trying to create a query that involves too many dimensions or facts that cannot be logically related, this error may occur.
  
  Solution:
  
  Review Data Model: Check the data model for the InfoObjects or tables involved. Ensure that the relationships defined between them are appropriate and do not exceed cardinality limits.
  Adjust Relationships: If you find that there are many-to-many relationships, consider redesigning the model to use a bridge table or to normalize the data to reduce complexity.
  Simplify Queries: If the error occurs while executing a query, try simplifying the query by reducing the number of dimensions or measures involved. Ensure that the query logic adheres to the cardinality rules.
  Check Aggregates: If you are using aggregates, ensure that they are correctly defined and that they do not introduce cardinality issues.
  Consult Documentation: Refer to SAP documentation or community forums for specific guidelines on cardinality limits and best practices in data modeling.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance on cardinality issues.
  SAP Community: Engage with the SAP Community forums where other users may have encountered similar issues and can provide insights or solutions.
  Training and Resources: Consider training or resources on data modeling in SAP BW or HANA to better understand how to design models that adhere to cardinality rules.
  
  If the problem persists after trying these solutions, it may be beneficial to consult with an SAP expert or support for a more in-depth analysis of your specific scenario.
