To execute from ABAP code an external Unix program

HI,
I would like to know how to execute from ABAP code an external Unix program and check for a return code?

HI,
There are different ways to this:
(1) OPEN DATASET <file> FOR OUTPUT 'unix command'
CLOSE DATASET <file>
This command executes the unix command and writes the output into <file>
Look into OSS Note 9391.
(2) or try the following program but unfortunately the command CALL SYSTEM is
not supported by SAP. If you are on R/3 2.1 - 2.2x you can get some idea's from the program SAPMSOS0.
REPORT ZUNIXCOM .
DATA: U_COMMAND(200).
Table for system messages
DATA: BEGIN OF RT OCCURS 100 ,
LINE(100) ,
END OF RT .
START-OF-SELECTION .
MOVE 'unix command' to U_COMMAND .
REFRESH RT.
CALL 'SYSTEM' ID 'COMMAND' FIELD U_COMMAND
ID 'TAB' FIELD RT-SYS .
LOOP AT RT.
WRITE : / RT-LINE .
ENDLOOP.
Reward Points if found helpfull..
Cheers,
Chandra Sekhar.

Custom Spell Check from ABAP Code without MS Word

Hi All,
I am working on a requirement where we need to check for misspelt words in a string that is received from another system. I have come across a number of FM's which can be used to check for spellings but all of the require MS Word to be installed in our PC, but I am looking for a solution that does not involve MS Word. If any of you have come across any external tool that can be called from ABAP code or any suggestion on a logic that can be built please pass it on. Any pointers or help in this regard would be highly appreciated.
Thanks,

Hi,
Try the "CF_WWSpeller" customtag which actually uses the

Calling Java Services from ABAP code

Hi,
How to call Java services (not web service) from ABAP code?
I have a requirement where JAVA team has developed some services that can be called from URL or from a Java application.
Ex: when this URL is executed,
http://localhost:8080/artemis7_802/triton/mycompany.remoteFunctions.RequirementsList.a7x?requestid=3023&requestname=I6PRAO1&skill=SAP&skill=JAVA
It returns a XML file on browser.
And I have no idea about the 2nd way i.e. from Java application!
Now, how can ABAP call these java methods?
I heard that something can be done via maintaining RFC destinations in SM59 to call Java services? Can this be done with my requirement?
Please help.
Thanks and regards,
Amey

Call of BW queries from ABAP code

Has anybody information about how is it possible to call a BW query from ABAP code with parametrization (specifying characteristics) ? In our development project it's a crucial part, beacuse we have to provide interim function modules to carry out some conversion routine on BW provided data, before we put it on the screen embedded in a Visual composer Iview.

Have a look at this:

How to insert abap code in LSMW generated program?

hi,
i m working on LSMW for loading data in SAP
i would like to insert abap code into the generated program....
it's because i have 1 BKPF segment (header data), 2 BSEG segments, but i cannot define rules by customizing for the second BSEG segment(LSMW doesn't permitt).
i already tried to insert code directly into the program, but obviously it disapears at each time i generate the program.
i saw that apparently a code insertion has already be made into this program and the subject of this insertion is to define rules for the second BSEG (exactly what i want to do....) and this modification doesn't disapear at new prog generation.....
Any idea ?

Hi
Why dont you use the FORM provided by LSMW
To use this please do the following
1.Goto option <b>Maintain Field Mapping and Conversion Rules</b>
2.Goto menu <b>EXTRAS->LAYOUT->Form Routines</b>
Here you will now get many options like
Global Data
Begin of Transaction
Begin of Processing
Begin of Record
like wise the End of these also.
Please put a breakpoint and check where you want to insert your code.
Note:
This is only for the Conversion Program and does not affect the main program used to update the Standard Tables
Hi , I was reading your earlier post .. It seems that you have worked on EMIGALL. Consider a similar situation, it is like writing the code in the events till CALL01...

How to call a transaction from ABAP code

Hi everybody,
How do I run a transaction from my ABAP code?
For example, through my ABAP code, I want to call the ME24 transaction (Maintain Purchase Order).
Thanks for the help,
Roy

CALL TRANSACTION
Syntax
CALL TRANSACTION ta { [AND SKIP FIRST SCREEN]
                    | [USING bdc_tab [bdc_options]] }.
Extras:
1. ... AND SKIP FIRST SCREEN
2. ... USING bdc_tab [bdc_options]
Effect
The statement CALL TRANSACTION calls the transaction whose transaction code is contained in data object ta. The data object ta must be of character type and must contain the transaction code in uppercase letters. If the transaction specified in ta cannot be found, an untreatable exception is triggered. The additions suppress the display of the initial screen and allow you to execute the transaction using a batch input session.
At CALL TRANSACTION the calling program and its data is kept, and after exiting the called transaction, processing is resumed in the calling program after the call.
When the transaction is called, the ABAP program linked with the transaction code is loaded in a new internal session. The session of the calling program is kept. The called program runs in an SAP LUW of its own.
If the called transaction is a dialog transaction, after loading the ABAP program the event LOAD-OF-PROGRAM is triggered and the dynpro defined as initial dynpro of the transaction is called. The initial dynpro is the first dynpro of a dynpro sequence. The transaction is finished when the dynpro sequence is ended by encountering the next dynpro with dynpro number 0 or when the program is exited with the LEAVE PROGRAM statement.
If the called transaction is an OO transaction (as of release 6.10), when loading all programs except class pools the event LOAD-OF-PROGRAM is triggered and then the method linked with the transaction code is called. If the method is an instance method, implicitly an object of the corresponding class is generated and referenced by the runtime environment. The transaction is finished when the method is finished or when the program is exited using the LEAVE PROGRAM statement.
After the end of the transaction call, program execution of the calling program resumes after the CALL TRANSACTION statement.
Note
At the statement CALL TRANSACTION, the authorization of the current user to execute the called transaction is not checked automatically. If the calling program does not execute a check, the called program must check the authorization. To do this, the called program must call function module AUTHORITY_CHECK_TCODE.
Addition 1
... AND SKIP FIRST SCREEN
Effect
This addition suppresses the display of a screen of the initial dynpro of a called dialog transaction. The addition AND SKIP FIRST SCREEN suppresses the first screen under these prerequisites:
For the initial dynpro, in the Screen Painter the own dynpro number must not be specified as the next screen number.
All mandatory input fields of the initial dynpro must be filled completely and with the correct values by the SPA/GPA parameters
If these prerequisites are met, that screen of the dynpro is displayed that is specified in the Screen Painter as the next dynpro of the initial dynpro.
Example
If the static next dynpro of the initial dynpro of the called dialog transaction FLIGHT_TA is not the initial dynpro itself, its screen is suppressed, because its input fields are filled using the SPA/GPA parameters CAR and CON.
DATA: carrid TYPE spfli-carrid,
      connid TYPE spfli-connid.
SET PARAMETER ID: 'CAR' FIELD carrid,
                  'CON' FIELD connid.
CALL TRANSACTION 'FLIGHT_TA' AND SKIP FIRST SCREEN.
Addition 2
... USING bdc_tab [bdc_options]
Effect
Use this addition to pass an internal table bdc_tab of row type BDCDATA from the ABAP Dictionary to a dialog transaction. The additions bdc_options control the batch input processing. When a transaction with addition USING is called, the system field sy-binpt is set to value "X" in the called program - while this transaction is running, no other transaction can be called with this addition.
The internal table bdc_tab is the program-internal representation of a batch input session and must be filled accordingly. The structure BDCDATA has the components shown in the table below.
Component Description
PROGRAM Name of the program of the called transaction
DYNPRO Number of the dynpro to be processed
DYNBEGIN Flag for the beginning of a new dynpro (possible values are "X" and " ")
FNAM Name of a dynpro field to be filled or batch input control statement, for example, to position the cursor
FVAL Value to be passed to the dynpro field or to the control statement
Using the internal table bdc_tab, you can provide any number of screens of the called transaction with input and user actions.
System Fields
sy-subrc Description
0 The batch input processing of the called transaction was successful.
< 1000 Error in the called transaction. If within the transaction a message was sent, you can receive it using the addition MESSAGES.
1001 Error in batch input processing.
Note
Outside of ABAP Objects you can specify the additions AND SKIP FIRST SCREEN and USING together. However, this does not make sense, because the addition AND SKIP FIRST SCREEN is desigend only to fill the mandatory input fields using SPA/GPA parameters, while the batch input table specified with USING controls the entire transaction flow including the display of the screens.
Example
Call of the Class Builder (transaction SE24) and display of class CL_SPFLI_PERSISTENT. The internal table bdcdata_tab contains the input for the batch input processing of the first dynpro (1000) of the transaction. Using structure opt, the batch input processing is set to suppress the first screen and to display the next screen in the standard size.
DATA class_name(30) TYPE c VALUE 'CL_SPFLI_PERSISTENT'.
DATA: bdcdata_wa TYPE bdcdata,
      bdcdata_tab TYPE TABLE OF bdcdata.
DATA opt TYPE ctu_params.
CLEAR bdcdata_wa.
bdcdata_wa-program = 'SAPLSEOD'.
bdcdata_wa-dynpro   = '1000'.
bdcdata_wa-dynbegin = 'X'.
APPEND bdcdata_wa TO bdcdata_tab.
CLEAR bdcdata_wa.
bdcdata_wa-fnam = 'BDC_CURSOR'.
bdcdata_wa-fval = 'SEOCLASS-CLSNAME'.
APPEND bdcdata_wa TO bdcdata_tab.
CLEAR bdcdata_wa.
bdcdata_wa-fnam = 'SEOCLASS-CLSNAME'.
bdcdata_wa-fval = class_name.
APPEND bdcdata_wa TO bdcdata_tab.
CLEAR bdcdata_wa.
bdcdata_wa-fnam = 'BDC_OKCODE'.
bdcdata_wa-fval = '=CIDI'.
APPEND bdcdata_wa TO bdcdata_tab.
opt-dismode = 'E'.
opt-defsize = 'X'.
CALL TRANSACTION 'SE24' USING bdcdata_tab OPTIONS FROM opt.

Error in determining Paper Format for Printout triggering from ABAP Code

Hi Experts,
I am trying to trigger a printout from my ABAP code using "NEW-PAGE PRINT ON ...... NEW-PAGE PRINT OFF" statement.
I am passing the Print Parameters using the FM "GET_PRINT_PARAMETERS" as below:
    CALL FUNCTION 'GET_PRINT_PARAMETERS'
      EXPORTING
        destination    = ls_options-tddest
        copies         = 1

        list_text      = 'ERROR NOTIFICATION'
        immediately    = 'X'
        release        = 'X'
        new_list_id    = ' '
*        expiration     =
        line_size      = 79
        line_count     = 23
        layout         = 'X_65_80'

      IMPORTING
        out_parameters = lv_params.
But I am facing a problem. Though I am passing X_65_80 to the LAYOUT in the Function Module, it is trying to print in LETTER format. But the specified printer as the printer supports only A4 paper format and as a result, I am not getting any printout.
Kindly help me with your suggestions to resolve this.
Thanks in advance.
Regards,
Keerthi

Hi,
I just found that this problem is even stranger.
I am able to print the said message on my local printer but when I try to print the same message on a different printer located at a different location, the printout does not get triggered. I am not getting any error messages also in this case.
What could be the possible reason for this?
Kindly share your views/experience with me on this one.
Thank you.

What is the use of a proxy client to test web service from ABAP code?

In NW640, we need to create a proxy client to test our web service from a ABAP code.
Why is this so? What is the significance of a proxy client? Is this mandatory? Can we test the webservice from a ABAP code without proxy client?

Hi Gopal,
There are two types of proxies that can be generated from ABAP - the client proxy (to call an internet web service) and a server proxy (to communicate with XI). It sounds to me like you are looking for information about the client proxy, if so you can see the following link from SAP Help:
http://help.sap.com/saphelp_nw04s/helpdata/en/e5/a68d10f4eb894087fc9c1c3f9ae433/frameset.htm
Hope this helps.

Access a OCI Catalog from ABAP code

Hi Experts,
We may need to access an OCI Catalog from an ABAP code. We will need to punch out the Catalog in a browser window, and somehow get the results from the browser back to the ABAP code.
Any idea of how can this be accomplished?
Thanks and regards,
José Omar

Accessing the catalog is nothing but creating a hook url and directing to that URL.
For eg. you should have the parameters read from the SPRO settings in SRM and then creating an URL in the fly.
But as of now you can have hard coded URLs being fed in.
ie you click on a link and you fire the exit plug as in Web dynpro in suspend mode.
The main criteria is to have the catalog OCI 4.0 complaint. (read mandatory fields etc in OCI 4.0 documentation)
Then once you shop from some items in the catalog , the OCI compliant catalog will send you the data in the required file format.
At the receiving end , PO etc . you should have a ABAP method (at resume ) that interprets this sent name-value pair file from the catalog. then populate this data where you want.
you can have a look at the SRM methods that does the same in ABAP.
This would the 20,000 feet or more process overview on how it works. Hope this helps
thanks
