2930127 - KUT Extension Field is missing from .REF file


An extension field created in the front-end UI using KUT tools (Adaptation mode) is missing in the reference file (.ref) to customer-specific fields.


  • SAP Business ByDesign.
  • SAP Cloud for Customer.
  • SAP Cloud Applications Studio.


Customers can enhance their SAP cloud solution by creating extension fields in the adaptation mode. In the studio, the partner can create references to these customer-specific fields. After that, a business logic can be implemented for the referenced fields in script files of a custom solution.


There are some restrictions when it comes to referencing customer-specific fields in your custom solution:

  1. You cannot reference a customer-specific field in a solution template.
  2. You cannot reference a calculated field.
  3. You can only reference a customer-specific field in the extension of a business object that has been released in the public solution model (PSM).
