• What is the cause and solution for SAP error message RSODP_ABAP_CDS337 - CDC annotation does not allow filter on table field &1-&2 ?

  The SAP error message RSODP_ABAP_CDS337 indicates that there is an issue with a Core Data Services (CDS) view where a filter is being applied to a table field that is not allowed according to the annotations defined in the CDS view. This typically occurs when the CDS view is designed in such a way that certain fields are not intended to be filtered, often due to the nature of the data or the way the view is structured.
  Cause:
  
  Annotation Restrictions: The CDS view may have annotations that restrict filtering on certain fields. For example, fields that are derived or calculated may not allow filtering.
  Field Type: The field being filtered may not be suitable for filtering operations, such as fields that are part of a complex data structure or fields that are not indexed.
  Join Conditions: If the field is part of a join condition, filtering on it may not be allowed due to the way the underlying data is structured.
  
  Solution:
  
  Review the CDS View: Check the annotations in the CDS view definition. Look for any @Analytics.dataCategory or similar annotations that might restrict filtering on the specified fields.
  Modify the Query: If possible, adjust the query or the filter condition to use a different field that is allowed for filtering.
  Change the CDS View: If you have control over the CDS view, consider modifying it to allow filtering on the required fields. This may involve changing the annotations or the structure of the view.
  Consult Documentation: Refer to the SAP documentation for CDS views and annotations to understand the limitations and best practices for filtering.
