Symptom
- Business object could not be published because of conflicts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>
Environment
SAP S/4HANA Cloud
Reproducing the Issue
- Create a custom business object (CBO) with the Custom Business Objects app
- Check the checkbox "Can be associated" and specify a key
- Create another CBO and connect the key ID from the first CBO with the type "Association"
- By publishing the new CBO the error will occur
Cause
- This is a known limitation currently
- This is a target of future improvements to the product
Resolution
- 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
