• What is the cause and solution for SAP error message ICA02070 - CDS view & contains no fields. ?

  The SAP error message ICA02070 indicates that a Core Data Services (CDS) view is defined but does not contain any fields. This can occur for several reasons, and understanding the cause is essential for resolving the issue.
  Cause:
  
  Empty Definition: The CDS view might be defined without any fields or with a SELECT statement that does not return any fields.
  Incorrect Annotations: The annotations in the CDS view might not be correctly defined, leading to no fields being recognized.
  Join Issues: If the CDS view is supposed to join multiple tables but the join conditions are incorrect or the tables do not have matching data, it may result in no fields being returned.
  Filter Conditions: If there are filter conditions applied that exclude all data, the view may end up with no fields.
  Syntax Errors: There could be syntax errors in the CDS view definition that prevent it from being processed correctly.
  
  Solution:
  
  
  Check the CDS View Definition: Review the definition of the CDS view to ensure that it includes fields in the SELECT statement. Make sure that the fields you want to include are correctly specified.
  Example:
  define view Z_MY_CDS_VIEW as select from my_table
  {
      key field1,
      field2,
      field3
  }
  
  
  Verify Annotations: Ensure that the annotations are correctly defined and that they do not inadvertently exclude fields.
  
  
  Review Join Conditions: If your CDS view involves joins, check the join conditions to ensure they are correct and that they will return data.

  Debugging: Use the ABAP Development Tools (ADT) in Eclipse to debug the CDS view and see how it is being processed.
