Consider this example:
I enable property inheritance with
(setq org-use-property-inheritance t)
--8<---------------cut here---------------start------------->8---
#+PROPERTY: header-args :tangle-mode (identity #o444)
#+PROPERTY: header-args+ :eval no-export
#+PROPERTY: header-args:R :session *R.EnergyBalance*
* Without properties
#+begin_src
13
#+end_src
Result from (org-babel-view-src-block-info):
,----
| Properties:
| :header-args :tangle-mode (identity #o444) :eval no-export
| :header-args:nil nil
| Switches:
| Header Arguments:
| :cache no
| :eval no-export
| :exports code
| :hlines no
| :noweb no
| :results replace
| :session none
| :tangle no
| :tangle-mode 292
`----
This is as expected.
* First Level
:PROPERTIES:
:header-args+: :tangle ./output/scripts/analysisCode.do.not.source.R
:header-args+: :output-dir ./output
:END:
#+begin_src R
13
#+end_src
Result from (org-babel-view-src-block-info):
,----
| Lang: R
| Properties:
| :header-args :tangle-mode (identity #o444) :eval no-export :tangle ./output/scripts/analysisCode.do.not.source.R :output-dir ./output
| :header-args:R :session *R.EnergyBalance*
| Header Arguments:
| :cache no
| :eval no-export
| :exports code
| :hlines no
| :noweb no
| :output-dir ./output
| :results replace
| :session *R.EnergyBalance*
| :tangle ./output/scripts/analysisCode.do.not.source.R
| :tangle-mode 292
`----
Also as expected, the header arguments are appended
** Second level
:PROPERTIES:
:header-args:R: :session *R.Results.Simp*
:header-args+: :tangle ./output/scripts/graphs.SimplificationOfWindProfileFits.R
:END:
Now the problem comes:
#+begin_src R
13
#+end_src
Result from (org-babel-view-src-block-info):
,----
| Lang: R
| Properties:
| :header-args :tangle-mode (identity #o444) :eval no-export :tangle ./output/scripts/graphs.SimplificationOfWindProfileFits.R
| :header-args:R :session *R.Results.Simp*
| Header Arguments:
| :cache no
| :eval no-export
| :exports code
| :hlines no
| :noweb no
| :results replace
| :session *R.Results.Simp*
| :tangle ./output/scripts/graphs.SimplificationOfWindProfileFits.R
| :tangle-mode 292
`----
The header arguments from Level One (:output-dir and :tangle) are not
there anymore and only the ones from the Second Level are used.
I would have expected the Level Two header arguments to be added to the
ones from Level One and the File wide?
--8<---------------cut here---------------end--------------->8---
Is this to be expected? I always thought, that the properties are
hierarchical, and that the ones from the lower levels / headers are used
as well?
Is this not the case, or id this a bug?
With property inheritance I would have expected the inheritance, but it
does not seem to make a difference?
Thanks,
Rainer

But it does not matter. See the docstring for `org-entry-get'. The setting
used in `org-babel-view-src-block-info' for INHERIT is `t'.
I believe there is a problem with `org-entry-get'. Here is an ECM:
--8<---------------cut here---------------start------------->8---
#+PROPERTY: aprop one
#+BEGIN_SRC emacs-lisp
(org-entry-get (point) "aprop" t)
#+END_SRC
#+RESULTS:
: one
* x
:PROPERTIES:
:aprop+: two
:END:
#+BEGIN_SRC emacs-lisp
(org-entry-get (point) "aprop" t)
#+END_SRC
#+RESULTS:
: one two
** y
:PROPERTIES:
:aprop+: three
:END:
#+BEGIN_SRC emacs-lisp
(org-entry-get (point) "aprop" t)
#+END_SRC
#+RESULTS:
: one three
I expected 'one two three'

Property inheritance doesn't work that way.
It only means that it will look higher in the hierarchy if current entry
doesn't have the property you want. This is explained in
`org-entry-get-with-inheritance' docstring:
"Get PROPERTY of entry or content at point, search higher levels if needed.
The search will stop at the first ancestor which has the property
defined."
Here, current entry has the property, so it ignores the one above.

OK - but this behavior is not influenced by the variable
org-use-property-inheritance. So what is the meaning of the variable
then?

The variable is checked when calling `org-entry-get' with a non-nil
INHERIT optional argument.
In this case `org-entry-get' calls `org-entry-get-with-inheritance'.

OK - let's move away from the programming in org and back to my question:
Looking at my example, it seems that the variable
org-use-property-inheritance has no impact on the header arguments,
i.e. no properties are inherited. So it seems that there is a bug, or a
severe misunderstanding on my side what property inheritance means.
From the help of the variable:
,----
| When nil, only the properties directly given in the current entry count.
| When t, every property is inherited. The value may also be a list of
| properties that should have inheritance, or a regular expression matching
| properties that should be inherited.
`----
Reading this, and the fact that I get the same properties irrespective
if I set org-use-property-inheritance to t or nil, I would assume that
there is something not correct or consistent.

I think you are confused with property accumulation. However property
inheritance predates this feature and totally ignores it.
Inheritance is an answer to the question "what should I do if the
property I'm looking for doesn't exist in the entry?". IOW, it only
kicks in, if at all, when property is /not found/ in current entry.
In your example, the property you're looking for is defined in every
entry, including the current one. Per above, Org doesn't even try to use
inheritance, and doesn't look at `org-use-property-inheritance'.
