SAP message SV 597 fixed

Background

Try to build a custom view cluster as following, all the field dependence are correct.

Issues

But when I try to activate, a popup window appears, I choose Yes, then error occurred, try to debug the error message with /H, but no clues.

Solution

I made a mistake, two tables has same key field, this is not allowed in view cluster hierarchy, bug was fixed after I add more key field to sub node table.
