Dynamic TABLE parameter in Sub routine call

Hi,
Is it possible to have a dynamic TABLE parameter in a sub-routine call? The structure of the internal table will be different during different calls to the sub-routine.
I have a subroutine which has the FM "HR_INFOTYPE_OPERATION" to update the infotype data for an Applicant. Now i want to call this subroutine for every Infotype update. So every time the structure of the internal table to be passed will vary depending on Infotype ( eg P0002 for Infotype 0002, p0006 for infotype 0006).
Any pointers will be appreciated.
Thanks in advance.

Hi Navin,
yes, why not.
just use a generic type parameter, i.e.
FORM process USING IT_00x type table IV_type typc.
It depend what yout FORM shall do. If you pass the types name, you can dynamically assign to a field-symbol of the respective type.

Clemens

How do i make this a sub routine

I have a little script to drill down folders and add comments to every folder and ever file inside the parent folder. It works perfectly well when run but itself. This was based heavily on the script found by NovaScotian here http://discussions.apple.com/thread.jspa?messageID=2182916&#2182916
I basically want to make this script into a sub routine, and i have tried various methods and havent been able to make it work.
global the_comments
global each_item
global pete
global ddp
global ddp2
set ddp to {}
set ddp2 to {}
set theLetter to "s"
set newDroppedFiles to choose folder with multiple selections allowed
to drilldown(afolder)
tell application "Finder"
set file_list to files of a_folder
set folder_list to folders of a_folder
end tell
repeat with i in file_list
processDrilledDownFile(i)
tell application "Finder"
set comment of pete to text of the_comments
end tell
end repeat
repeat with i in folder_list
copy i to end of ddp2
drill_down(i)
end repeat
end drill_down
on processDrilledDownFile(a_file)
copy a_file to end of ddp
end processDrilledDownFile
set the_comments to (do shell script "/usr/bin/defaults read com.Rich.move " & theLetter & "Text")
repeat with each_item in newDroppedFiles
set pete to each_item
tell application "Finder"
set comment of each_item to text of the_comments
end tell
drill_down(pete)
end repeat
repeat with each_item in ddp
tell application "Finder"
set comment of each_item to text of the_comments
end tell
end repeat
repeat with each_item in ddp2
tell application "Finder"
set comment of each_item to text of the_comments
end tell
end repeat

Your script already includes several subroutines, so the trick is separating those out first.
Essentially your script consists of three elements - global declarations, your own subroutines and a run handler. Since there's no explicit 'on run', everything that's not inside a subroutine becomes the run handler.
Therefore what you should do is strip out all the code that's not a global declaration or an existing handler and just wrap that in a new 'on subroutinename()... end subroutinename' block.
For sanity's sake I'd also add a specific run handler to bind it all together.
This means you'll end up with something like:
<pre class=command>global the_comments
global each_item
global pete
global ddp
global ddp2
on run
my myNiftySubroutine()
end run
to drilldown(afolder)
tell application "Finder"
set file_list to files of a_folder
set folder_list to folders of a_folder
end tell
repeat with i in file_list
processDrilledDownFile(i)
tell application "Finder"
set comment of pete to text of the_comments
end tell
end repeat
repeat with i in folder_list
copy i to end of ddp2
drill_down(i)
end repeat
end drill_down
on processDrilledDownFile(a_file)
copy a_file to end of ddp
end processDrilledDownFile
on myNiftySubroutine()
set ddp to {}
set ddp2 to {}
set theLetter to "s"
set newDroppedFiles to choose folder with multiple selections allowed
set the_comments to (do shell script "/usr/bin/defaults read com.Rich.move " & theLetter & "Text")
repeat with each_item in newDroppedFiles
set pete to each_item
tell application "Finder"
set comment of each_item to text of the_comments
end tell
drill_down(pete)
end repeat
repeat with each_item in ddp
tell application "Finder"
set comment of each_item to text of the_comments
end tell
end repeat
repeat with each_item in ddp2
tell application "Finder"
set comment of each_item to text of the_comments
end tell
end repeat
end myNiftySubroutine</pre>
There's just one other observation - most of the globals are not actually needed since you can just pass them as parameters to the subroutines.
I'm also not sure what the purpose of the script is - the upshot seems to be that you're setting the comment of items in the Finder, however, since you:
<pre class=command> set comment of pete to text of the_comments</pre>
and pete is a global pointing to the folder you're processing, surely this sets the comment of the folder x times, where x is the number of files in the folder - in other words if there are 100 files in the folder, you set the comment of the folder 100 times and don't touch the files themselves. Is that what you intend?

Reg, sub routine

how can u call a sub-routine from other programmes?

Hi,
Start of Content Area
Naming Subroutines Locate the document in its SAP Library structure
With the PERFORM statement, you can call subroutines which are coded in the same ABAP program (internal calls), or subroutines which are coded in other ABAP programs (external calls).
You can also specify the name of the subroutine dynamically at runtime, and call subroutines from a list.
Internal Subroutine Calls
To call a subroutine defined in the same program, you need only specify its name in the PERFORM statement:
PERFORM subr [USING    p1 p2... ]
             [CHANGING p1 p2... ].
The internal subroutine can access all of the global data of the calling program.
Example
REPORT demo_mod_tech_perform_int.
DATA: num1 TYPE i,
      num2 TYPE i,
      sum TYPE i.
num1 = 2. num2 = 4.
PERFORM addit.
num1 = 7. num2 = 11.
PERFORM addit.
FORM addit.
sum = num1 + num2.
PERFORM out.
ENDFORM.
FORM out.
WRITE: / 'Sum of', num1, 'and', num2, 'is', sum.
ENDFORM.
This produces the following output:
Sum of          2 and          4 is          6
Sum of          7 and         11 is         18
In this example the subroutines addit and out are defined at the end of the program. addit is called by the program and out is called by addit. The subroutines have access to the global fields num1, num2 und sum.
External Subroutine Calls
The principal function of subroutines is for modularizing and structuring local programs. However, subroutines can also be called externally from other ABAP programs. In an extreme case, you might have an ABAP program that contained nothing but subroutines. These programs cannot run on their own, but are used by other ABAP programs as pools of external subroutines.
However, if you want to make a function available throughout the system, you should use function modules instead of external subroutines. You create function modules in the ABAP Workbench using the Function Builder. They are stored in a central library, and have a defined release procedure.
You can encapsulate functions and data in the attributes and methods of classes in ABAP Objects. For any requirements that exceed pure functions, you can use global classes instead of external subroutines.
When you call a subroutine externally, you must know the name of the program in which it is defined:
PERFORM subr(prog) [USING    p1 p2... ]
                   [CHANGING p1 p2... ] [IF FOUND].
You specify the program name prog statically. You can use the IF FOUND option to prevent a runtime error from occurring if the program progdoes not contain a subroutine subr. In this case, the system simply ignores the PERFORM statement.
When you call an external subroutine, the system loads the whole of the program containing the subroutine into the internal session of the calling program (if it has not already been loaded). In order to save memory space, you should keep the number of subroutines called in different programs to a minimum.
Example
Suppose a program contains the following subroutine:
REPORT formpool.
FORM header.
WRITE: / 'Program started by', sy-uname,
         / 'on host', sy-host,
           'date:', sy-datum, 'time:', sy-uzeit.
ULINE.
ENDFORM.
The subroutine can then be called from another program as follows:
REPORT demo_mod_tech_perform_ext.
PERFORM header(demo_mod_tech_formpool_1) IF FOUND.
In this example, no data is passed between the calling program and the subroutine.
Specifying Subroutines Dynamically
You can specify the name of a subroutine and, in the case of external calls, the name of the program in which it occurs, dynamically as follows:
PERFORM (fsubr)[IN PROGRAM (fprog)][USING    p1 p2... ]
                                   [CHANGING p1 p2... ]
                                   [IF FOUND].
The names of the subroutine and the external program are the contents of the fields fsubr und fprogrespectively. By using the option IF FOUND, you can prevent a runtime error from being triggered if no subroutine with the name fsubr is found. If you omit the parentheses, this variant of the PERFORMstatement behaves like the static variant.
Example
Assume a program contains the following subroutines:
PROGRAM formpool.
FORM sub1.
WRITE: / 'Subroutine 1'.
ENDFORM.
FORM sub2.
WRITE: / 'Subroutine 2'.
ENDFORM.
Dynamic Subroutine Specification:
PROGRAM form_test.
DATA: progname(8) TYPE c VALUE 'FORMPOOL',
      subrname(8) TYPE c.
subrname = 'SUB1'.
PERFORM (subrname) IN PROGRAM (progname) IF FOUND.
SUBRNAME = 'SUB2'.
PERFORM (subrname) IN PROGRAM (progname) IF FOUND.
This produces the following output:
Subroutine 1
Subroutine 2
The character field progname contains the name of the program, in which the subroutines are contained. The names of the subroutines are assigned to the character field subrname.
Calling Subroutines from a List
You can call a subroutine from a list as follows:
PERFORM idx OF subr1 subr2 ... subrn.
The system calls the subroutine specified in the subroutine list in position idx. You can only use this variant of the PERFORMstatement for internal subroutine calls, and only for subroutines without a parameter interface. The field idx can be a variable or a literal.
Example
REPORT demo_mod_tech_perform_list.
DO 2 TIMES.
PERFORM sy-index OF sub1 sub2.
ENDDO.
FORM sub1.
WRITE / 'Subroutine 1'.
ENDFORM.
FORM sub2.
WRITE / 'Subroutine 2'.
ENDFORM.
This produces the following output:
Subroutine 1
Subroutine 2

Include or sub-routine in user-exit

Hi all,
i want to put a sub-routine in my customer user-exit (CMOD).but i can not put the subroutine.
can i put a subroutine or include statement in a user exit?
correct answers will be rewarded.
Thanks

You can make subroutine calls inside a User exit, only if the exit is part of a function pool. All the subroutines can be placed in an include in the function pool & can be called with a Perform Statement from the User Exit.

Hi leela,
you can use one global variable for this as flag.
ex:
data flag type c.
perform sub1.
if flag = 'X'.
perform sub2.
endif.
form sub1.
if (condition yes).
flag = 'X'.
endif.
endform.
form sub2.
endform.
this will work well

How to pass parametrs into application

I have a applet which i would like to run as a application. Question is how to pass parametrs which applet need. WHen i use this.getParameter("nameofparam") i got stupid NullPointerException.
Thanks for any advice
Tomas

The getParameter method tries to look at the HTML document in which the applet is embedded, so it will always return null if there's no HTML document to inspect (note that the method itself isn't throwing a NullPointerException - that's thrown when you try to do something with the null parameter).
So you'll have to use a completely different way of setting the parameters. The simplest is to provide a default value for if getParameter returns null:
String parameter = getParameter("nameofparam");
if (parameter == null)
parameter = "Default value";Alternatively you could pass parameters at the command line and reference them with the array passed to the main method, or if your application has a GUI they could be taken from a menu, etc.

Smart forms not displaying result from sub routine

I am working on a smart form and need to display the description of the fabric code. Under Form Routines, I create a sub routine
FORM fcc_values USING gv_fabrictext.
which is supposed to store the description in gv_fabrictext. GV_FABRICTEXT has been declared in global data as char64. Then I call prior to displaying my table as
perform fcc_values using gv_fabrictext.
And then insert the field &gv_fabrictext& in cell but this does not display any result
I know for sure that this sub routine works as I have tested it separately as a test program. Any ideas?

1. put break point at ssf_function madulename and check field value.
or
2 fm_name export parameter ur not mentioned
or
3 global variable not defined properly
go through above. still if u didnt get
need program where the problem to find.

Passing values to sub VI and writing data to controls

As part of a control interface for a VFD i am interfacing with using Modbus TCP I wanted to try and compartmentalise some of my code into a subVi
However in doing so I am having a lot of trouble understanding how I can read the current drive settings for the Ramp up and Down values and update those values into the main faceplate of my control.
The sub Vi is tested and works exactly how I want. Selecting Read (latch on pressed) reads the registers from the drive and outputs it to the controls and the indicators. The indicators were incorporated because I did not know how to pass the data out of the sub vi without them. Updating works to write the current value in the controls to the VFD registers.
However when I incorporate this VI into my larger project the values are always displayed as zeros if I have the switch set to latch. However i do see a momentary flash of the correct values soon after pressing the read button or if i change it from latched operation to switched, however i would prefer it to opperate in a latched mode so as to reduce communication overheads to the drive.
Solved!
Go to Solution.

Modbus sub vi.pdf ‏943 KB

Hi,
A number of suggestions:
1. Use references and property nodes to set FP indicators from a subVI (you can learn more here and here)
2. Don't put output indicators inside Cases. When the case is not Read, the VI outputs default values to the outputs and gives you the zero values.
Good luck,
Danielle
