2549081 - Business Object Could Not Be Published Because of Conflicts


  • Business object could not be published because of conflicts
  • The key indicator cannot be set for the type of field <FIELD ID> of node <NODE ID>



Reproducing the Issue

  1. Create a custom business object (CBO) with the Custom Business Objects app
  2. Check the checkbox "Can be associated" and specify a key
  3. Create another CBO and connect the key ID from the first CBO with the type "Association"
  4. By publishing the new CBO the error will occur


  • This is a known limitation currently
  • This is a target of future improvements to the product


  • Currently it is not possible to define key fields of type "association" in general
  • This will be possible beginning with the 1908 cloud release
  • To workaround this you will need to ensure the fields are the same data type between both CBOs or duplicate the key fields and standard fields to associate
