Read Program code from another program

Hi,
I would like have ABAP code which reads another program and displays the coding of it.
Regards,
Vijayakumar

HI,
The SUBMIT statement accesses an executable program rep. The executable program is executed as described under Calling Executable Reports.
The program name rep can either be specified directly or as the content of a character-like data object name. The data object name must contain the name of the program to be accessed in block capitals. If the program specified in name is not found, an irretrievable exception is generated.
The selscreen_options additions can be used to determine the selection screen for the program accessed and to supply it with values.
The list_options additions allow you to influence the output medium and the page size in the basic list for the program accessed.
You can schedule the program for background processing by specifying job_options.
Addition
... AND RETURN
Effect
The AND RETURN addition determines the object accessed by the runtime environment after program access is completed:
Without the AND RETURN addition, the internal session of the program accessed replaces the internal session of the calling program in the same position in the call sequence. Once program access is completed, the system returns to before the position from which the calling program was started.
As of Release 6.10, the content of the system field sy-calld at SUBMIT is copied by the calling program without AND RETURN. Before 6.10, the system entered the value "X", which was incorrect when the program was accessed from the first program in a call sequence.
The addition AND RETURN starts the executable program in a new internal session. The session for the calling program is retained. Once program access is completed, program execution for the calling program continues after the SUBMIT statement.
Note
When the SUBMIT statement is executed, the system runs an authorization check for the authorization group specified in the program attributes.

Reading the output from another program.

I haven't used Java in a good long while so I need someone to point me in the right direction. I have a C program that I call from a command line (windoze boxen) and it spits out some neat data. I can call it from inside a Java program, but how do I then read the output from the calling Java program? I'd just alter the C program, but I lost the source.

This article explains how to correctly execute another program from your
Java program, and read its output:

How to call an alv report from another program and return back

 Hello ,
I am calling one abap program (Prgm B) from another program (Prgrm A).
Here, Prgm B is an ALV report. I have fetch some data from Prgem B that gets stored in an internal table.
Now, I am using below code in Prgrm A,
SUBMIT Prgrm B VIA SELECTION-SCREEN
 WITH SELECTION-TABLE rspar
 EXPORTING LIST TO MEMORY
 AND RETURN.
When Prgrm A executed, it lead me to selection screen of Prgrm B and when I click F8, it shows me the report output, In short, it doesnt return back to Prgrm A. It ends up showing me the alv report if Prgrm B even afetr using RETURN statement.
I want to get back to Prgrm A by fetching some data from Prgrm B.
Please let me know, if i am missing something.

Hi,
I ma trying to CALL TRANSACTION 'ME33K from another program, but it is not working. The transactions is opening, but it is not opening with the contract number (ls_ekpo-ebeln) i am passing.
ls_ekpo-ebeln does have a valued when CALL TRANSACTION 'ME33K is called.
In debug, I noticed the "value" is blank when step into CALL TRANSACTION 'ME33K .
 WHEN 'EBELN'. "Contract
 l_field = 'EVRTN'.
 IF ls_ekpo-ebeln <> ''.
 GET PARAMETER ID 'VRT' FIELD l_field. "EVRTN.
 SET PARAMETER ID 'VRT' FIELD ls_ekpo-ebeln.
 CALL TRANSACTION 'ME33K AND SKIP FIRST SCREEN.
 SET PARAMETER ID 'VRT' FIELD ls_ekpo-ebeln.
 ENDIF.
Any help or suggestions would be great.
Thanks,

Dear Naing,
I execute the same code
IF ls_ekpo IS INITIAL.
GET PARAMETER ID 'VRT' FIELD LS_EKPO.
SET PARAMETER ID 'VRT' FIELD ls_ekpo.
CALL TRANSACTION 'ME33K' AND SKIP FIRST SCREEN.
SET PARAMETER ID 'VRT' FIELD ls_ekpo.
ENDIF.
And it is working.
Try to do de simple sintax.
A program with one pararmeter to introduce the contract number.

Using numbers for roster information. Imported from another program. Now seem to have extra headers, one listing name, address, etc.

Using numbers for roster information. Imported from another program. Now seem to have extra headers, one listing name, address, etc. & another A, B, C. They don't mesh & can't get rid of either. All info there, but can't change width of columns.

I think my problem is that I have inadvertently created three tables (I only want one). I have included a screen shot of the light grey line under B and the words Table 1 behind it.

Recieve data from another program

hi, i'm trying to recieve some kind of data from another program i know where is the output of the program the problem is that i don't know how to get these datas. for example my program is writing the output in a temporary file but i'd like to recieve these datas without a temp file. the question is: Is possible to make a class that be listening to the meddle and when any program send any data to its it recieves??? if yes how can i do it?
i'm working with girds and is easy to descover where my output will arrive the only problem is how to recieve.

Or a pipe. In unix you can create a named pipe with mkfifo, which can hadilly do this kind of transfer.

How to import photos from another program on computer eg. Adobe Photoshop

Can photos be imported to IPhotos from another program on the same computer eg. Adobe Photoshop?

Photos aren't "in" Photoshop. They're in the Finder and has just been set to use Photoshop to open them.
You can import files into iPhoto by
The File -> Add to Libary command
Drag and Drop to either the iPhoto window or the iPhoto icon.

How to create a variant to a report from another program at run time

Hi experts,
when i am using FM : /OSP/REPORT_CREATE_VARIANT to create a report variant from a program then i am getting an error 'For object /OSP/ERPNR , number range interval 01 does not exist ', how should i avoid it or can any one help me out to create a report variant from another program at run time with the results of the program.so that i can execute the report from here with this variant

If i understand you,
- You can use a FM like [RS_CREATE_VARIANT|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=rs_create_variant+&adv=false&sortby=cm_rnd_rankvalue] to create a variant and then use it in the [SUBMIT|http://help.sap.com/erp2005_ehp_03/helpdata/EN/fa/096d67543b11d1898e0000e8322d00/frameset.htm] statement USING SELECTION-SET.
- But you may also use SUBMIT with WITH parameters which doesnt require variant creation and with much less programming efforts.
- You can mix the two solutions also.
So what is you actual requirement, also look at some documentation like [ Scheduling a Job: Full-Control Method|http://help.sap.com/erp2005_ehp_03/helpdata/EN/fa/096ce5543b11d1898e0000e8322d00/frameset.htm]

Checking whether field-symbol from another program is assigned?

Hi all
I'm attempting to access a FS from another program.
As the FS can be assigned, or unassigned within that program, how do I checked for that in my calling program?
e.g. calling program;
FIELD-SYMBOLS: <fs> TYPE STANDARD TABLE.
DATA: lv_var(40) type c.
lv_var = '(ZTGT_PROG)<read_fs>'.
ASSIGN (lv_var) TO <fs>. " statement might dump...

Hi
Go through this doc and use accordingly
Field Symbols
Field symbols are placeholders or symbolic names for other fields. They do not physically reserve space for a field, but point to its contents. A field symbol cam point to any data object. The data object to which a field symbol points is assigned to it after it has been declared in the program.
Whenever you address a field symbol in a program, you are addressing the field that is assigned to the field symbol. After successful assignment, there is no difference in ABAP whether you reference the field symbol or the field itself. You must assign a field to each field symbol before you can address the latter in programs.
Field symbols are similar to dereferenced pointers in C (that is, pointers to which the content operator * is applied). However, the only real equivalent of pointers in ABAP, that is, variables that contain a memory address (reference) and that can be used without the contents operator, are reference variables in ABAP Objects.
All operations programmed with field symbols are applied to the field assigned to it. For example, a MOVE statement between two field symbols moves the contents of the field assigned to the first field symbol to the field assigned to the second field symbol. The field symbols themselves point to the same fields after the MOVE statement as they did before.
You can create field symbols either without or with type specifications. If you do not specify a type, the field symbol inherits all of the technical attributes of the field assigned to it. If you do specify a type, the system checks the compatibility of the field symbol and the field you are assigning to it during the ASSIGN statement.
Field symbols provide greater flexibility when you address data objects:
If you want to process sections of fields, you can specify the offset and length of the field dynamically.
You can assign one field symbol to another, which allows you to address parts of fields.
Assignments to field symbols may extend beyond field boundaries. This allows you to address regular sequences of fields in memory efficiently.
You can also force a field symbol to take different technical attributes from those of the field assigned to it.
The flexibility of field symbols provides elegant solutions to certain problems. On the other hand, it does mean that errors can easily occur. Since fields are not assigned to field symbols until runtime, the effectiveness of syntax and security checks is very limited for operations involving field symbols. This can lead to runtime errors or incorrect data assignments.
While runtime errors indicate an obvious problem, incorrect data assignments are dangerous because they can be very difficult to detect. For this reason, you should only use field symbols if you cannot achieve the same result using other ABAP statements.
For example, you may want to process part of a string where the offset and length depend on the contents of the field. You could use field symbols in this case. However, since the MOVE statement also supports variable offset and length specifications, you should use it instead. The MOVE statement (with your own auxiliary variables if required) is much safer than using field symbols, since it cannot address memory beyond the boundary of a field. However, field symbols may improve performance in some cases.

Syntax Diagram
FIELD-SYMBOLS
Basic form
FIELD-SYMBOLS <fs>.
Extras:
1. ... TYPE type
2. ... TYPE REF TO cif
3. ... TYPE REF TO DATA
4. ... TYPE LINE OF type
5. ... LIKE s

7. ... TYPE tabkind
8. ... STRUCTURE s DEFAULT wa
The syntax check performed in an ABAP Objects context is stricter than in other ABAP areas. See Cannot Use Untyped Field Symbols ad Cannot Use Field Symbols as Components of Classes.
Effect
This statement declares a symbolic field called <fs>. At runtime, you can assign a concrete field to the field symbol using ASSIGN. All operations performed with the field symbol then directly affect the field assigned to it.
You can only use one of the additions.
Example
Output aircraft type from the table SFLIGHT using a field symbol:
FIELD-SYMBOLS <PT> TYPE ANY.
DATA SFLIGHT_WA TYPE SFLIGHT.
ASSIGN SFLIGHT_WA-PLANETYPE TO <PT>.
WRITE <PT>.
Addition 1

Addition 2
... TYPE REF TO cif
Addition 3
... TYPE REF TO DATA
Addition 4
... TYPE LINE OF type
Addition 5
... LIKE s
Addition 6
... LIKE LINE OF s
Addition 7
... TYPE tabkind
Effect
You can define the type of the field symbol using additions 2 to 7 (just as you can for FORM parameters (compare Defining the Type of Subroutine Parameters). When you use the ASSIGN statement, the system carries out the same type checks as for USING parameters of FORMs.
This addition is not allowed in an ABAP Objects context. See Cannot Use Obsolete Casting for FIELD SYMBOLS.
In some cases, the syntax rules that apply to Unicode programs are different than those for non-Unicode programs. See Defining Types Using STRUCTURE.
Effect
Assigns any (internal) field string or structure to the field symbol from the ABAP Dictionary (s). All fields of the structure can be addressed by name: <fs>-fieldname. The structured field symbol points initially to the work area wa specified after DEFAULT.
The work area wa must be at least as long as the structure s. If s contains fields of the type I or F, wa should have the structure s or at least begin in that way, since otherwise alignment problems may occur.
Example
Address components of the flight bookings table SBOOK using a field symbol:
DATA SBOOK_WA LIKE SBOOK.
FIELD-SYMBOLS <SB> STRUCTURE SBOOK
DEFAULT SBOOK_WA.
WRITE: <SB>-BOOKID, <SB>-FLDATE.

How to open-up a pdf file to a particular page via java? (file and page number from another program)

I have created an Access 2003 Form. Data is entered. The data can be viewed once entered in the same form format, with one addition. The addition is a link to another program where we store files. The files stored are pdf documents. Each document is a scanned file (500+ pages). The link can open-up the pdf file. I want the link to open-up the pdf file to a particular page. I will supply the page number from the database.
I am aware of Adobe Acrobat 7.0 PDF Open Parameters using a URL that specifies the file to be opened plus actions to be performed once the file is openend (i.e. http://example.org/doc.pdf#page=3). However, the 3rd party program transfers a file from a server to the client via java. The file does not go via a web browser. The java code transfer the file directly from the file server to the the client.
Any idea how to accomplish the task of viewing a particular page with the process flow described?
I am using Adobe Acrobat 7.0 Professional.

So you are reading this file in a standalone version of Acrobat? If so then use the PDF Open Parameters /a option via the command line.
Sabian
Example:
C:\Program Files\Adobe\Acrobat 7.0\Acrobat>Acrobat.exe /A "zoom=1000=OpenActions" "C:\Program Files\Adobe\Acrobat 7.0\Acrobat\SimpleSubmit.pdf"
Where:
Path to Acrobat: C:\Program Files\Adobe\Acrobat 7.0\Acrobat>Acrobat.exe
Note: The example starts in the Acrobat application directory
Switch: /A
Parameter Syntax: "zoom=1000=OpenActions"
Path to file: "C:\Program Files\Adobe\Acrobat 7.0\Acrobat\SimpleSubmit.pdf"
Note: The quotes are very important for the syntax to work appropriately.

How to edit a program dynamically called from another program

Hi all,
Can anyone help me in coding for a program which call's another
report dynamically from selection screen(for instance z_dynam_called)
and retreive the whole content of the dynamically called program(z_dynam_called)
into an internal table and replace the contents of the internal table with some new code and put it back in z_dynam_called and save it.
Thanks in advance.
Needful will be rewarded with points

Hi,
Follow this:
1) U can pass data from one program to another in a single login using SAP memory......
2) u can create a DBtable update dat table using ur first pgm and fetch from second program.....
3) U can pass the report output using EXPORT TO MEMORY addition and get it back using IMPORT FROM MEMORY..........
Eg:
Export the selected rows to the next program
EXPORT final TO MEMORY ID 'ABC'.
CALL TRANSACTION 'XXX'.
XXX is the tcode for the other program where u want to import the values.
In the second program
INITIALIZATION.
IMPORT the internal table from the first program
IMPORT final FROM MEMORY ID 'ABC'.
