I try to query various intermediate nodes in a graphical HANA calculation view.

On some nodes it works just fine, like:

select field1, field2 from "_SYS_BIC"."ZBW/SOME_FOLDER/MY_HANA_VIEW/dp/Union_1" ...

On other nodes like

select field1, field2 from "_SYS_BIC"."ZBW/SOME_FOLDER/MY_HANA_VIEW/dp/MY_NODE" ...

it fails with message

Invalid table name: could not find table/view "_SYS_BIC"."ZBW/SOME_FOLDER/MY_HANA_VIEW/dp/MY_NODE"

Why does it work on some nodes and doesn't on others? HANA DB version is 2.00.076.
