Reproducing the Issue

  1. Create a Custom Business Object YY1_CBO1. You have checkmarked Can Be Associated in the custom business object you want to associate.
  2. Create a custom CDS view YY1_CDS_VH as explained in Creating Custom CDS Views. Is is recommended to select the Value Help scenario. You have used the associated custom business object view YY1_CBO1 as Primary Data Source.
  3. Make an association to a SAP released view in custom CDS view YY1_CDS_VH.
  4. Navigate to the custom business object YY1_CBO2 in which you want to use the value help view and click on the Fields tab.
  5. Create a new field FIELD1 or select an already existing field.
  6. Select the type Association to Business Object and enter the following information: Business Object YY1_CBO1 and Value Help View YY1_CDS_VH.
  7. Publish your custom business object YY1_CBO2.

Accessing the generated UI based on custom business object YY1_CBO2, it is not supported to populate FIELD1 with the entries from the associated data source in YY1_CDS_VH


The purpose of the "Association to Business Object" field type feature for Custom Business Objects is selecting a dataset from the associated business object, be it a custom or standard one, but not from any otherwise associated data sources.

Adding data to a Custom Business Object via an association in a custom CDS view (type value help) is not supported.
