• What is the cause and solution for SAP error message SD_CDS_ENTITY049 - Reference field info requires reffield and reftable to be set ?

  The SAP error message SD_CDS_ENTITY049 indicates that there is an issue with the configuration of a Core Data Services (CDS) view, specifically related to reference fields. This error typically arises when the system expects certain fields to be defined but they are not properly set up in the CDS view.
  Cause:
  The error occurs when:
  
  A reference field is defined in the CDS view, but the required fields reffield (reference field) and reftable (reference table) are not specified or are incorrectly configured.
  The CDS view is trying to establish a relationship with another table or entity, but the necessary metadata is missing.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the CDS View Definition:
  
  Open the CDS view in the ABAP Development Tools (ADT) or the relevant transaction (e.g., SE11).
  Ensure that the reference fields are correctly defined with both reffield and reftable attributes.
  
  
  
  Define Reference Fields:
  
  If you are using reference fields, make sure to specify the correct reference table and field. This can be done in the CDS view definition using the appropriate annotations.
  Example:
  @AbapCatalog.sqlViewName: 'Z_MY_CDS_VIEW'
  @AbapCatalog.compiler.compareFilter: true
  @AccessControl.authorizationCheck: #CHECK
  define view Z_MY_CDS_VIEW as select from my_table
  {
    key field1,
    field2,
    @ObjectModel.referenced: { 
      entity: 'ReferencedEntity', 
      field: 'ReferencedField' 
    }
    field3
  }
  
  
  
  
  Check for Annotations:
  
  Ensure that any necessary annotations for the reference fields are correctly applied. This includes checking for any missing or incorrect annotations that might affect the reference relationship.
  
  
  
  Activate the CDS View:
  
  After making the necessary changes, activate the CDS view to ensure that the changes take effect.
  
  
  
  Test the CDS View:
  
  Execute the CDS view to verify that the error has been resolved and that the data is being retrieved correctly.
