Reasons of different behavior in “UI and Reports” list
The problem is that different systems UIs and Reports in the display logic is not the same. On GRE210 even XT9 / 715, which will only show OData out, I debug the front and back, Usage data is returned in the background, explain this to do in business context PRODUCT of the extension field can be added to the view I_PRODUCTWD, because it is AvailablityCode Y
And all I CDS and related usageTypeCode are - so were all filter out. To take another system QJ3 / 500, where all can show the field usage, not just the U. This QJ3 / 500 is a sandbox system, today hung up, I can not go look at the code, I would like to ask in the end, what is the working behavior as designed in
In system A, you can only get 5 entries in UI and Reports list:
In system B, there are much more entries:
how to debug this difference:搞懂了哈， 从代码推断只有这里 UI,Report 里为 X 的 CDS view 才会出现在 Fiori UI 的 tab 里。在 XT9/715( S4 on premise )所有和 product 相关的 CDS view 都是 false，所以看不到。而另外一个 S4 on cloud 系统里，和 product 相关的 CDS view 都是 true。 所以结论是两个系统的 behavior 都是正确的，只是因为 reigstry 里设置 不一样，所以最后在 UI list 里显示的东西也不一样。
