You receive an error FieldExtensibility.GerRefFields failed while editing section group of Custom Embedded Component in the UI designer.


  • SAP Cloud for Customer
  • SAP Business ByDesign
  • SAP Cloud Application Studio

Reproducing the Issue

  1. Login to Cloud Application Studio.
  2. Open the relevant solution.
  3. Open the custom Embedded Component via UI designer.
  4. Edit the EC and select the section group.
  5. Try to change the anchor settings
  6. Error appears in the pop-up " FieldExtensibility.GerRefFields failed"


The error is an expected behavior, as custom embedded is added to the Custom Business Object is not on a standard BO. Adding of Extensibility anchors is allowed to be created only on standard UIs and not on custom UIs.


You can add fields on the UI through modeling in  and not through Extensibility Explorer in UI designer
