• What is the cause and solution for SAP error message SD_CDS_ENTITY081 - Association &: Conditions must not contain any LOB columns ?

  The SAP error message SD_CDS_ENTITY081 indicates that there is an issue with the conditions defined in a Core Data Services (CDS) view, specifically that the conditions must not contain any Large Object (LOB) columns. LOB columns typically refer to data types that can store large amounts of data, such as BLOB (Binary Large Object) or CLOB (Character Large Object).
  Cause:
  The error occurs when you attempt to use LOB columns in the WHERE clause or in the conditions of a CDS view. SAP does not support the use of LOB columns in certain contexts, particularly in the definition of CDS views, because they can lead to performance issues and complications in data retrieval.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the CDS View Definition: Check the definition of the CDS view where the error is occurring. Look for any conditions that involve LOB columns.
  
  
  Remove LOB Columns from Conditions: If you find any LOB columns being used in the conditions, you will need to remove them or replace them with non-LOB columns. 
  
  
  Refactor the Logic: If the logic of your application requires the use of LOB data, consider refactoring your approach. You might need to:
  
  Create a separate CDS view that does not include LOB columns for filtering.
  Use a different method to handle LOB data, such as fetching it in a separate query after the main data retrieval.
  
  
  
  Test the Changes: After making the necessary adjustments, test the CDS view to ensure that it works as expected without the LOB columns in the conditions.
  
  
  Related Information:
  
  CDS Views: Core Data Services (CDS) is a framework for defining semantically rich data models in SAP. It allows for the creation of views that can be consumed by various applications.
  LOB Data Types: LOBs are used to store large amounts of data, such as images, documents, or large text fields. In SAP, these are typically handled differently than standard data types.
  Performance Considerations: Using LOB columns in queries can lead to performance degradation, which is why SAP restricts their use in certain contexts.
  
  If you continue to face issues after following these steps, consider consulting SAP documentation or reaching out to SAP support for further assistance.
