How to build a subroutine calling tree ?

[Former Member]

Hi,

I'd like to build a calling tree for a given program (or function module anyway).

Something that tells me wich forms or function modules are called in my program.

Something that gives me a hierarchy :

Program1

-

---

> FM 1

-

---

> Form 1

-

---

> Form 2

-

---

> FM 2

-

---

> Form 3

-

---

> Form 4

-

---

> Form 5

And so on...

Does such a tool exist ?

Thank you for your help.

yes, these are function modules which used to display tree

CALL FUNCTION 'RS_TREE_CONSTRUCT'
       TABLES
            nodetab            = t_node
       EXCEPTIONS
            tree_failure       = 1
            id_not_found       = 2
            wrong_relationship = 3
            OTHERS             = 4.

  IF sy-subrc <> 0.
    sy-msgty = 'S'.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    STOP.
  ENDIF.

  CALL FUNCTION 'RS_TREE_LIST_DISPLAY'
       EXPORTING
            callback_program      = 'YH1063_TREETEST'
            callback_user_command = 'USER_COMMAND'
            callback_top_of_page  = 'TOP_OF_PAGE'
            callback_gui_status   = 'TREE'.

where the sturcture of t_node will be like :

fs_node-name  = 'Programs.   << label name
  fs_node-nlength = 50.
  fs_node-color = 1.
  fs_node-tlevel = 1.              << Level depth
  APPEND fs_node TO t_node.

and to know about function modules, forms, tables, symbols etc, one must have the knowledge of SCAN statement

t_node is the table which will contain your actual data.

Hi,

Thank you for your answer.

These function modules seems to be used to build a tree.

But what I'm looking at is a tool to build automatically a calling tree.

I mean a tool to which I give the program name, and that answers me the call tree.

Do you know such a tool ?

Thanks anyway.

I'm not aware of exactly such a program in standard SAP. You could write one using the SCAN keyword, which tokenises ABAP code.

Alternatively, you could use the code inspector, which tells you which components of a program get hit as it is run.

How would you want to handle:

IF condition.
  PERFORM myform.
ENDIF.

I did not find any tool, so I started to build it...

[Former Member]

Being curious here: but what are you going to use it for?

[Former Member]

I work on a large an old project.

This will let us analyze and get a better view of some obscure reports...

And we'd like too to build a reverse tree. That is to say as where-used list, but with a hierarchy. It would help in finding the impacts of some devs.

[Former Member]

Mmm. I understand. But how will you go about recursive form calls? How will you deal with dynamic calls of forms and/or function modules?

It sounds like a good plan, but i doubt it will be helpful as a tool for analysis. As i see it (admittingly, i don't know what you are planning to program in it) you will only see the calls of functions, forms, modules and nothing more. It would only serve as an overview tool.

[Former Member]

That's why I was looking for an existing tool, because it's a bit tricky to write...

So at the moment an overview tool is better than nothing

But if you know more about the subject, I'd be glad to learn

[Former Member]

I don't know the release you work with, but on my system (ECC6) there is the code inspector.

I haven't tried it out with a serious program, but it does some analysis on a program.

[Former Member]

I know Code Inspector, but certainly not completely.

Have some doc about it ?

How would you use it to get a hierarchy of the routines of the program ?

[Former Member]

Haven't looked at it myself (in a serious way, only wrote a little trash program and ran CI on it). So on my to do list: check out Code Inspector.
