I just found interesting function in New ABAP Editor. It’s not actually any hidden, but I think not many use it.
UPDATE: from comments it seems it is available in SAP from “EHP6 731” (screenshots are from it)
You can found it in context menu (right click) on code:
It has different outputs on different places. For example here is what it shows when used on FM call:
It also works on method calls, variables (showing their type) and other code…
What might be very helpful is that you can copy text from tooltip and use it (eg. declare variables of needed type for FM/method call).
Instance method: GET_DDIC_FIELD
Returns type description for Dictionary type
Value(P_LANGU) TYPE SYLANGU Optional SY-LANGU
Value(P_FLDDESCR) TYPE DFIES Optional
Imagine having this tooltip in switchable side panel (similar like “repository browser” in SE80) and interactive on cursor position.
No more double-clicking on methods, functions, variables etc.. to see their type, description…
Wouldn’t that be amazing? 🙂
