How To Fix ESH_CDS_VAL006 - Fields of view &1 is too deep for analysis

SAP Error Message - Details

• Message type: E = Error

• Message class: ESH_CDS_VAL -

• Message number: 006

• Message text: Fields of view &1 is too deep for analysis

What causes this issue?

Analysis of fields in the search view <(>&<)>1 is aborted as the fields
are too deep in the hierarchy. Each field in the search view is analyzed
for the source from where the fields are derived from(top-down). The
source can be another CDS view or table field. The top-down analysis is
carried out only for a fixed length of the hierarchy, for performance
reasons. Once the threshold is reached, the analysis is no longer
carried out.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Analyze the fields manually.

• What is the cause and solution for SAP error message ESH_CDS_VAL006 - Fields of view &1 is too deep for analysis ?

  The SAP error message ESH_CDS_VAL006 indicates that the fields of a Core Data Services (CDS) view are too deep for analysis. This typically occurs when the structure of the CDS view is complex, involving multiple nested associations or deep hierarchies, which can exceed the limits set by the SAP system for processing.
  Cause:
  
  Deep Hierarchies: The CDS view may have associations or joins that create a deep hierarchy, making it difficult for the system to analyze the data efficiently.
  Complex Structures: The view may include multiple layers of nested fields or complex calculations that exceed the allowed depth for analysis.
  Performance Limitations: The system has performance limitations to ensure that queries can be executed in a reasonable time frame, and deep structures can lead to performance degradation.
  
  Solution:
  
  
  Simplify the CDS View:
  
  Review the structure of the CDS view and try to simplify it by reducing the number of associations or joins.
  Flatten the hierarchy where possible, or break down the view into smaller, more manageable views.
  
  
  
  Use Views with Less Depth:
  
  If the current view is too complex, consider creating additional views that aggregate or summarize data at a higher level, which can then be used in the analysis.
  
  
  
  Check for Unused Fields:
  
  Remove any fields that are not necessary for the analysis to reduce the complexity of the view.
  
  
  
  Optimize Associations:
  
  Ensure that associations are necessary and that they are optimized for performance. Avoid unnecessary deep associations.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation for guidelines on the maximum depth of CDS views and best practices for designing efficient CDS views.
  
  
  
  Testing and Validation:
  
  After making changes, test the CDS view to ensure that it still meets the business requirements and that the error no longer occurs.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates regarding this error message.
  Performance Tuning: Consider performance tuning techniques for CDS views, such as using appropriate annotations and optimizing the underlying database tables.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have implemented.
  
  By addressing the complexity of the CDS view and following the above solutions, you should be able to resolve the ESH_CDS_VAL006 error and improve the performance of your data analysis.
