What causes this issue?

No source structure is mapped to the target structure. The system cannot
generate the runtime object that is required to transfer data, as the

You can map a source structure to the target structure in the
<ZK>Structure Mapping</> area.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
